Fleimia Schomburgkiana isa valid name, it is not the case with 
Dioscorea Schomburgktana, in spite of the later description of 
Kunth, because under Diroscorea Schomburgkiana there is no 
reference to Helmia Schomburgkiana (Vienna rules, art. 37). 
Therefore I ought to to be responsible for the new binomial Dzos- 
corea Schomburgkiana. 
But there is a rule which is above all others: ‘obscurity and 
confusion must be avoided.” If that is admitted for a name (Vienna 
rules, art. 51, 4°), it must be recognized also in the quotation of the 
author. Hence we propose to maintain the author name, Kunth, 
for Dioscorea Schomburgkiana because: ist, there is no doubt 
that in the two instances Kunth had exactly the same species in view ; 
2d, if a Dioscorea Schomburgkiana (Kunth) Hochr. would come 
into use, it would lead to the false idea that this plant is different 
from Dioscorea Schomburgkiana Kunth nomen. If one adopts 
our point of view, the plant quoted above must be considered as 
the type of the species.

There is no doubt that the oldest name is pedunculatus and, 
adopting the new binomial, it is an advantage to possess a definite 
specimen as a type, z. e., the one of Cruikshank, quoted by Hooker. 
Miers based his species only on a drawing made by himself.
