STUDIES ON THE INDIAN SPECIES OF THE GENUS SALIX L., SECTIONS CAESIAE, CHEILOPHILAE AND HELIXWnft SPECIAL REFERENCE TO IDENTIFICATION AND DISTRIBUTION By Sukla Chanda, A. Pramanik and G.G. Maiti (Abstract: …. only in the north western Himalayan region of India these sections Caesiae, Cheilophilae have single representative member viz. S. myricaefolia Andersson and S. wilhelmsiana M. Bieb. respectively and the section Helix is represented by 2 species as S. pycnostachya Andersson and S. sericocarpa Andersson. In the present account the distributional pattern, taxonomic characters and identification of these 4 species of Salix are discussed with two keys one for sections and the other for species.)

Salicaceae (including Flacourtiaceae) Fortnight: SALICACEAE basics (1) : 11 posts by 6 authors.
In India two genera Populus L. and Salix L. are reported under Salicaceae sensu stricto. A key to the genera is presented below:
1a. Vegetative buds with many outer scales; terminal buds frequently present; catkins mostly pendulous;
floral bracts dentate or lobed; flower with disc but without any glands ………………………… 1. Populus
1b.Vegetative buds with one outer scale; terminal bud absent; catkins generally erect; occasionally
spreading or pendulous; floral bracts generally entire; flowers without any disc, but with glands.. 2. Salix
Some addition which I found from Flowers of Himalaya by Polunin which might be useful. (… may add or alter if anything is not correct)
SALIX : The flowers are insect pollinated. The leaves are narrow and short stalked.
POPULUS: Flowers are wind pollinated numerous and pendulous. Leaves with broad blade and slender leaf stalk.
The list of sp. mentioned
Trees or shrubs
Cultivated sp. Large arboreal trees
S.alba White willow
S.excelsa Crack willow
S. babylonica. Weeping willow
Dwarf alpine shrublets, usually less than a meter.
Leaves tiny less than a cm
Leaves usually more than a cm
In Maharashtra there are only two species mentioned under Salicaceae.
Thanks … You just miss one little thing from this book that Salix acmophylla is also mentioned as a cultivated species here. Flowers of the Himalaya (by Polunin and Stainton) is a good book, but it deals only central and western Himalaya (in the introductory part you could find the map and areas they covered). So we can get only 13 species (9 wild and 4 cultivated) of Salix and 5 species of Populus.
Talbot (1911) in his book Forest Flora of the Bombay Presidency and Sind had also added Salix babylonica and mentioned the other two species as you said. According to him this species is cultivated in “Poona, Bombay and elsewhere throughout the presidency”.
Salicaceae (including Flacourtiaceae) Fortnight: SALICACEAE basics (2) : 4 posts by 3 authors.
Deciduous trees, or shrubs; branches terete.Leaves mostly alternate; blades variously shaped, often long and narrow; petioles frequently short; stipules small, free, deciduous. Catkin solitary, axillary to terminal, appearing before, with or after leaves; male flowers: sessile, bracteate; glandular; gland 1 or 2, fleshy and juicy; stamens 2-many; filaments free, or connate; female flowers: sessile, bracteate; glandular; ovary sessile or stipitate. Infructescence slender; capsules ovoid-conical, 2-valved; seeds oblong to ellipsoid, small, comose.
The genus Salix L. have 400 species, chiefly distributed in northern temperate regions ( Mabberley, 2008 ), a few are also found in the Southern Hemisphere excludingAustralia and New Guinea. According to Fang ( 1987) there are ca. 526 species of Salix L. in the World, most of which are distributed in the Northern Hemisphere, with only a few are distributedto Southern Hemisphere. In India most of the species are found in the Himalaya from Jammu & Kashmir to Arunachal Pradesh. A few viz. S. tetrasperma and S. ichnostachya are available in the tropical and subtropical zones as well. S. tetrasperma is the most widely spread species of Salix in India, found almost all the parts.
Collection and identification of Salix are pretty laborious job as it found in very hostile hill slopes and look very similar in the field. As no such elaborate flower is present in this member, identification can be confirmed after dissecting the flower in many cases.
The majority of the species of Salix are grown along or near the river banks, lakes, etc. even grow on boulder-strewn ground near stream. The common habitat of Salix nearer to water bodies reflects the fact that they need constant moisture supply for immediate seed germination. Many willows are grown as ornamentals and for screens, shelter, holding banks and some of the species for the tuff flexible branches from which baskets are made.

I have updated eFI (efloraofindia) page on Salix
Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.
Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.
If someone can provide complete list of Indian species with source references it will be wonderful.
Thanks, Sukla ji, for the wonderful fortnight on Salicaceae.
Any comments/ corrections are welcome

I request you to pl. go through & point out mistakes, if any. I hope this will aid in identifications in future. If anybody can send images of other species of this genus (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
