Dear Jacob: Thank you for the ID.... and the write up you have included is verbatim from WIKI, this particular essay is at: http://en.wikipedia.org/wiki/Haworthia
It would have sufficed to have given this link... or if one must include the entire essay VERBATIM... it behooves the writer to give the URL link... Even if WIKI is an open source resource, a citation must be given, otherwise it implies YOU wrote the whole essay , and since it not the case.... there are conclusions to be drawn, you add them up ... I leave it to you to do so... I hope you will take an active part in this group, and always give reference/citations....like one does when writing any scientific paper... thanks Usha di ================= On Tue, Apr 24, 2012 at 9:49 PM, Dr Jacob Thomas <[email protected]>wrote: > It is* Haworthia limifolia* of* Liliaceae*.
