[Taxacom] molecular species description

[Tim Dickinson]

not exactly *description* but rather identification of novelty from 
molecular data:

Botanical Journal of the Linnean Society, 2005, 148, 445–457

from the introduction:
"Here we demonstrate the utility of DNA fingerprinting in placing novel 
plant taxa. When we predicted a new species of Vaccinium L. on the 
strength of a fragment of DNA , isolated from a single seedling grown 
from seed of an unripe berry collected in 1997 near the summit of Fan Xi 
Pan (3142 msm) the highest peak in the northern Vietnam (Vander Kloet 
and Patterson, 2000 [Bot. J. Linn. Soc. 134: 575–586]), reaction from 
the scientific community was muted to say the least with most 
taxonomists claiming Missourian ancestry!

Nonetheless, when our seedling sprang into bloom on 12 IV 03, ( Figure 
1) six years after germinating, it was obviously different from other 
sympatric Vaccinia ( Table 1) by at least four characters, e.g., V. 
hiepii Vander Kloet differs from V. chunii Merrill in twig indumentum as 
well as leaf dimensions, leaf colour, and nervation, which is more than 
sufficient for specific status, thereby corroborating our DNA evidence, 
and more importantly the utility of DNA fingerprinting to measure 
biodiversity. Even fragments of DNA, whether mitochondrial or 
chloroplast or nuclear, when properly amplified, are usually sufficient 
to designate a new species."
