Phyllanthus key for eFlora of India … : 8 posts by 6 authors.


Here is a simple key to identify species of Phyllanthus using simple exomorphic characters. To start with i have included only species which are collected from my study area (Tiruvannamalai in Tamil Nadu). I think it includes most of the species discussed earlier in this group. But, there are about 50 species of Phyllanthus in India. So, we need more pictures and information on other species too, to make it complete. I am working on description and other aspects of these taxa, in line with our (ambitious) ‘eflora of India’ program.



Key to species of Phyllanthus L.

11b Leaves oblong-lanceolate; capsules warty; seeds tuberculate……………..Phyllanthus virgatus





Thank you … for this simple and easy to understand effort.

I was checking the Kew herbarium for Glochidion and Caesaria plant, to my surprise I got several herbarium specimens for Glochidion ellipticum with type specimen name mentioned as Phyllanthus diversifolius in one and in another as Phyllanthus malabaricus, why is this so ? would request you to enlighten us on this please. Thank you.


 its a difficult question to give a straight forward answer, so…let me try!

Its all part of taxonomy and nomenclature! It shows the different level of our understanding about taxa at different periods of time. It also illustrates the complexity of the group with diverse habit/morphology within this group.
The names mentioned by you were published during 1860s when the understanding about the genus was completely different. Due to some common feature, for e.g. ‘phyllanthoid branching’ several different species were treated under the genus Phyllanthus even they are morphologically very different. However recent molecular phylogenetic studies helped us to understand the possible relationship between different taxa and thus their improved taxonomic treatment. The taxon namely Phyllanthus malabaricus (for e.g.) was considered a species under Phyllanthus by Mueller who described the plant during 1865. But the latest revisioners (Webster, Govaerts etc.) realized that this plant has more affinity with and having similar morphological characters (also pollen morphology) to Glochidion and further realized that it is nothing but one of the several forms/variations of an existing species G. ellipticum described by Beddome, in this case. Hence the name Phyllanthus malabaricus has become a taxonomic synonym (based on different Type) to Glochidion ellipticum.
Fact: 1. Genera like Phyllanthus, Glochidion, Flueggea, Berynia, Sauropus etc come under same tribe – Phyllantheae (these are closely related).
Fact: 2. Several species, treated earlier under different genera (as much as 55 genera) are currently treated under the genus Phyllanthus http://www.ars-grin.gov/cgi-bin/npgs/html/genus.pl?9303), an another development of taxonomic research!]
To put it in a simple way, in the present case, Mueller misidentified his collection and published as a new species under wrong genus! However, we should remember that one-and-a-half centuries ago, there was not much information technology, communication etc. and a botanist at one corner of world had less chance to know the happenings of taxonomic research development at the other corner. We are now in a far better environment, wherein we can access the information real time, across the globe!!!
Hope i have not confused you so much!

Thank you so much … for the explanation and further links. You have made a very complicated subject simple to understand ! Atleast now I know why the mix- up, the confusion is due to Mueller ! I will read up more on the two facts mentioned by you.

One of the journal articles has given the distinction of floral disc- present in Phyllanthus but totally absent in Glochidion this should help us in identifying them. Will have to read in detail and perhaps will have more questions ! Thank you once again.


Thanks for great contribution … Here is link to my recent research contributions on Phyllanthus.

Large pdf files may take sometime to open. Hundreds of new links will be visible very soon through above mentioned link, as Google is bit slow in indexing the contributions.

I have updated eFI (efloraofindia) page on Phyllanthus in line with Flora of India Vol. 23 (2012).

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.

Any comments are welcome.
