with the 3-parted perianth. L. wallichii Wedd. in the Annales is P. peduncularis 
Wall, and nothing more, why then Weddell should have subsequently separated it 
even as a variety from P. peduncularis which is it, with the addition of other 
supposed synonyms, may remain a mystery. 
But L. wightii can not be used for the species with the unequally 3-parted 
perianth: E. ovatum Wight is not doubtfully a synonym of L. toightii, but its 
sole basis, and as already stated, Wight both figured and described the other type 
of flowers. 
If Procris peduncularis be considered to have been published by Royle, L. 
peduncularis will stand for the species which extends to the Philippines : for the 
other, following the synonymy, a. new combination will be necessary, based on 
Procris bbtusa Royle. If not, the oldest name for the former will be obtained 
by a transfer of Wight’s specific name: 'for the latter, again following synonymy, 
by a transfer of that of Dalzell. It is the pistillate perianth of the latter alone, 
which is described by Weddell, as well as in Genera Plantarum, Die E at iir lichen 
Pflanzenfamilien, Flora of British India, and Flora Indiae Batavae. 
The only fbreign specimen available for comparison here is Henry 9738 A, from 
the Province of Yunnan, China: in flower and inflorescence it is an excellent 
match for the Philippine plants cited, but it is a' much more robust plant with 
larger leaves. Further segregation may possibly be necessary, but- it must be 
reserved for some one who has access to ail the types. On the two-species con- 
ception, the range of L. peduncularis is at least India and China ; the genus 
extends from the west coast of Africa to the Society Islands. 
6. PELLIONIA Gaudich. 
Polychroa Lour. FI. Cochineh. (1790) 559, has been doubtfully reduced by 
• Wright 25 to Pellionia, and the description, while not conclusive, presents no 
obstacles, as far as it goes. If the two prove the same, Polychroa is the older 
by 36 years: the case is not covered by the list of nomina conservanda.
