Flora Iranica was compiled by Austrian botanist K.H. Rechinger from 1963 until his death in 1998, then completed by committee in 2005. It contains 181 fascicles (~chapters), each devoted to a plant family. Individual chapters are available from NHBS.

Structurally, the work is an annotated bibliography. Entries are in Latin. Annotations are in Latin, English, or German – depending on entry. Most fascicles contain plant images and/or illustrations.

The fascicle I’m presenting here is for Moraceae. The primary author is the renown Polish botanist K. Browicz. There are 15 pages of text plus 8 figures. Here is the first page:

Here’s K. Browicz’ description of the family Moraceae, translated from Latin by Google:

Trees and shrubs, monoecious or dioecious, with milky latex. Leaves alternate, sometimes opposite, deciduous or evergreen, simple, entire or sometimes serrated or lobed; veins pinnate or palmate. Stipules 2, lateral or above the bud forming a cap, often deciduous. Flowers minute, very reduced, actinomorphic, unisexual, capitate or pseudospicate or arranged on the inner face of the concave receptacle. Perianth segments 4, free or connate, reduced or lacking. Male flowers with 4 stamens (or reduced to 1-2), opposite perianth segments; distinct filaments. Female flowers on the superior or inferior ovary, usually unilocular; styles usually 2, filiform. Fruit small, achaenium or drupe. Infructescence syncarpe or syconium. Seeds usually endowed with endosperm.

Next we’ll have a look at each Genus present in greater Iran.

The first Genus is Morus. K. Browicz begins with a few references, then gives the following general description:

Deciduous trees and shrubs. Gems scales 3-6. Leaves alternate, simple, serrate or toothed, undivided or lobed, with 3-5 nerves arising from the base. Stipules membranous, lateral, small, soon deciduous. Flowers 4-merous, monoecious or dioecious, both sexes in pedunculate axillary panicles. Perianth 4-parted. Stamens 4. Ovary ovoid or subglobose, bilocular, with one abortive sac. 2-part style. Ovule solitary, pendulous. Compressed fruits and drupes enclosed in an expanded succulent perianth, aggregated in an ovoid or cylindrical succulent syncarp. Seeds with fleshy endosperm.

Next we’ll look at 3 Morus species in the study area.

Genus Ficus.

Trees and shrubs mostly monoecious, lactic, sometimes branched. Leaves semi-evergreen or deciduous, alternate, rarely opposite, simple, entire or serrate, often variously lobed. Stipules connate, including the terminal bud, falling, forming a circular scar. Flowers enclosed in a fleshy, ovoid or globose or pyriform receptacle, provided with a small ostium. Male flowers with a 2-6-partite perianth, with 1-2, rarely 3-6 stamens. Female flowers with a similar perianth or a reduced perianth or none. Ovary straight or oblique, with a solitary short or filiform style, eccentric or lateral. Achenes enclosed in the growing receptacle, forming a fig with it. Endosperm often sparing.

F. carica, F. johannis and F. palmata form a very difficult complex of deciduous figs. Specific limits are far from clear, intra-specific variation in each of the three species is homologous, and their extreme forms further complicate the situation. Many varieties and forms, and even individual species, have been recognised in the past.

The so-called cultivated fig is sometimes thought to have originated from hybridization of several species, with the Arabian peninsula being suggested as the place of origin. On the basis of the rich SW Asiatic collections (though not as yet from Arabia) it can be suggested that, if the cultivated fig is of hybrid origin, then its parents could be F. carica subsp. rupestris and F. johannis; the ranges of these two species overlap in Iran. On the other hand, F. carica subsp. carica seems to represent this very hybrid, cultivated and selected for millenis; it also, as a result anthropo- or zoo-choric dispersal, readily establishes itself. This latter characteristic makes it very difficult to define its true native distribution and has led to differing views about its status in, for instance, the Mediterranean area, the Caucasus, and N Iran.

If this suggested hypothesis is correct then the substantial variation in the leaf lobing of F.carica subsp. carica is more understandable, since it is inherited from F. johannis. The occurrence of forms with un-lobed leaves could be a result of the influence of F. carica subsp. rupestris. It is possible that this taxon deserves to be given specific rank; its range is SW Anatolia, N Syria, N Iraq and SW Iran. However, intermediate forms between subsp. rupestris and subsp. carica are found in the north of the range of subsp. rupestris in Anatolia and Iran.

F. carica

Deciduous shrub or tree to 10 m tall (or taller). Juvenile branches green, eventually brown, glabrous or ± pubescent; older branches grey, smooth, thick, rigid, few-branched. Leaves 5-20(-35) cm long, sometimes longer, undulate-crenate to dentate, ± lobed or undivided, often cordate, scabrid, often ± pubescent to tomentose beneath, exceptionally subglabrous. Petiole 2-8(-12) cm long, glabrous to tomentose. Individual figs, 2-3 cm (in cultivated forms up to 8 cm) long, pyriform and stipitate or subglobose, sessile or pedicellate, greenish or yellow-green to violet, shortly hairy or (especially in cultivated forms) glabrous. Achenes yellow, subspherical, c. 1.5 mm long.

F. carica subsp. carica

A vigorous shrub or tree. Leaves large, up to 10 cm, sometimes up to 35 cm long, suborbicular, ± lobed, sometimes sublobed; sinuses between the lobes reaching a third or half of the blade, sometimes broad lobes, sometimes much deeper sinuses, sometimes narrow lobes, spathulate, entire margin, only slightly pubescent at the apex. Ficus often pyriform, stippled, sessile or subsessile.

F. carica subsp. rupestris

Mostly shrubby. Leaves broadly ovate to ovate-oblong, clearly longer in width, 5-10(-15) x 4-8(-12) cm, apex often obtusely acute or obtuse, base deeply cordate, both sides scabrous, often softly pubescent beneath. Figs often hairy, varying in shape and size, pyriform, sometimes clearly stipitate or globose, sessile. Pedicel up to 2 cm long. Stipe sometimes thin-most subfiliform, equal to or longer than the pedicel.

Ficus johannis

Shrub 1-3 (sometimes 4) m tall, sometimes a small tree, densely branched. Branchlets rather slender, juvenile pubescent or subglabrous. Leaves usually small, with 3-5 short, incised-serrate lobes folded, sometimes long, narrow lobes sometimes almost reduced to the main veins, base cordate to truncate, veins often very prominent beneath. Petioles pubescent or glabrous. Figs pyriform, sometimes stipe-shaped, or globose, usually distinctly pedicellate.

F. johannis shows an even greater range of variation than F. carica. Sometimes the whole range of leaf lobing can be seen on the same individual; the same also seems to be true for peduncle length and the stipe of the syconium. Some extreme forms have very narrowly lobed leaves and so incised that the leaf blade is almost restricted to the network of the main veins. These latter forms appear to be most frequent on coppice shoots, browsed, pruned or very young individuals. There is no reason to give them separate varietal status.

@RosyPosy

Because of the great variation of F. johannis it is not surprising that several individual species have been described in the past: F. geraniifolia MIQ., F. persica BOISS., F. malvastrifolia WARB., F. vitifolia WARB. and F. afghanistanica WARB. Only the last named deserves to be maintained, though only at subspecific level. Compared with subsp. johannis it has larger leaves and figs. It appears that, as is also so with F. carica subsp. carica, F. johannis subsp. afghanistanica is a cultivated form possibly originally selected in the Kerman area of Iran.

At the northern limit of its range of F. johannis subsp. afghanistanica hybridizes with F. carica subsp. carica. Thus in southern Turkmenia and in Iranian Khorassan there are individuals with more or less intermediate characteristics.

Ficus johannis subsp. johannis

Leaves usually only 1-3 (sometimes 6) cm long, very variable, shortly and broadly lobed to deeply lobed; sinuses between lobes sometimes almost reaching the base of the blade, sometimes very narrow lobes, completely incised-serrate at the margins; such leaves are usually but not always developed on vegetative branches; leaves are usually pubescent beneath, sometimes on both sides. Petioles 0.5-2(-3) cm long. Figs small, 1-1.5(-2) cm long, usually stipitate. Length of stipules variable, very short, c. 5 mm up to 1.5-2 cm long. Pedicels 0.5-2.5(-3) cm long, as figs ± pubescent.

Two variations (of many) of F. johannis subsp. johannis. Notice the syconia stem lengths compared to their diameters.

Ficus johannis subsp. afghanistanica

Leaves large, usually 7-9(-13) cm long, deeply lobed, scabrous or sub-glabrous, cordate; narrow lobes, especially the median margin, entirely obtusely toothed, provided with secondary deeply incised toothed lobes reaching half the blade. Petiole up to 5 cm long. Figs 2-3(-3.5) cm long, usually pyriform, stippled, glabrous or sometimes densely hairy. Pedicels up to 2 cm long.

Example of F. johannis subsp. afghanistanica. Notice the leaf lobes are wider than some F.j. johannis individuals.

Ficus palmata

Ficus palmata subsp. palmata

… occurring in E Africa (Ethiopia, Somalia, Sudan) and in the southern part of the Arabian Peninsula, has the leaves more elongate, distinctly acute or acuminate and only weakly pubescent or glabrous. The figs are similarly pubescent.

Ficus palmata subsp. virgata

General distribution: SE Persia, eastern Afghanistan, Pakistan, India, Nepal.

Cultivated (landrace) in Pakistan and India. In Pakistan F. palmata subsp. virgata is probably locally selected for fruits. Forms of this species with large leaves more or less cordate at the base are sometimes wrongly considered to be F. carica.

Shrub or small tree, 4-10 cm tall, bark ± smooth. Juvenile branches tomentose or pubescent, often glabrous, purplish-brown. Leaves broadly ovate or suborbicular, mostly 5-10(-12) cm long, apex shortly acute to obtuse, base cuneate or truncate or subcordate, exceptionally cordate, margin ± coarsely dentate or dentate-serrate, mostly not lobed, above or sometimes both sides scabrous, exceptionally subglabrous, softly tomentose beneath. Petiole 1.5-5(-7) cm long, softly tomentose. Figs axillary, solitary, subglobose or pyriform and then stipitate, 1.5-2.5 cm long, pedicellate, mostly tomentose, yellow to purple when ripe. Stipe 2-10(-12) mm long. Pedicel 4-15(-20) mm long, densely pubescent.
