Sir, I would like to use this thread to record what I have observed about *Solanum nigrum* complex around our region. I have uploaded 3 members which have been identified as *villosum*, *nigrum* and *americanum*. But, my *nigrum* species received a question mark in a personal mail and I have addressed it during last fortnight <https://groups.google.com/forum/#!msg/indiantreepix/2vYi8lfFTEI/ckzHwIN9sUgJ>. The points of doubt were - 1) *S. nigrum* is uncommon species, 2) flowers after spring 3) *nigrum* is almost similar to *villosum* (?).
- all 3 I have recorded so far are still flowering and fruiting. Flowering season depends on climatic and soil condition of a place. What month(s) suits in HP for a given species may not be same in WB, and we will have to take care of elevation too - description of the 3 species in FoC is similar to the pdf at http://www.bioversityinternational.org/uploads/tx_news/Black_nightshades__Solanum_nigrum_L._and_related_species_337.pdf - nowhere I could find any document saying *villosum* fruits can be black or purple Assuming my *nigrum* species has been correctly identified I would like to record my observation of this plant - 1. *S. nigrum* has almost entire leaf, different looking than the *villosum* I have, one or two bears similarity to *villosum* to some extent 2. the leaf size of well built (which has been not disturbed to grow) *nigrum* is rather bigger than the sizes mentioned in FoC or in pdf. Leaf at base can have lamina of more than 10 cm long. 3. *nigrum* fruits here have both strongly reflexed sepals and not so recflexed ones. Usually they are reflexed 4. on one occasion I have seen a few flowers on a plant have light purplish petals but other flowers on the same individual were white I think my *nigrum* rather shows feature of *Solanum scabrum* Mill. or have a tendency toward it! I didn't find any *S. villosum* with entire leaf.
