I will be very frank and that is I have much difficulty using herbarium specimens because I am wired to look for both color and fine structural details and these are either distorted or missing entirely from dried specimens, especially very old specimens...and I have seen where 'The Experts' have been mislead by old dried,distorted specimens...
There is just no way to know for sure what a dried plant looked like as a Living plant...someone can take all the specialized training available on how to interpret dried specimens but it is always guesswork to some degree... I fully realize that dried specimens was all that was possible under some circumstances and these old specimens can still provide material for comparative DNA analysis , but , I think if a person wants to know what Living plants look like , then you must have either Living plants or good high resolution photos to use as a reference...hopefully holographic imaging will be available in the not too distant future... regards, Ron On Wednesday, March 14, 2012 11:59:01 PM UTC-4, Vijayasankar wrote: > > I've shared Convolvulaceae week: RVS4: Ipomoea > alba<https://docs.google.com/document/d/1gA9PK8sV7_lASflpKVXgdB8qE64_YDFmqa5GO5cv_-g/edit> > - > tracked<https://docs.google.com/document/d/1gA9PK8sV7_lASflpKVXgdB8qE64_YDFmqa5GO5cv_-g/edit> > Click to open: > > - Convolvulaceae week: RVS4: Ipomoea > alba<https://docs.google.com/document/d/1gA9PK8sV7_lASflpKVXgdB8qE64_YDFmqa5GO5cv_-g/edit> > - > tracked<https://docs.google.com/document/d/1gA9PK8sV7_lASflpKVXgdB8qE64_YDFmqa5GO5cv_-g/edit> > > > Dear all, > > Ipomoea alba, from Andhra Pradesh... > > > Google Docs makes it easy to create, store and share online documents, > spreadsheets and presentations. > [image: Logo for Google Docs] <https://docs.google.com> - > tracked<https://docs.google.com> >
