The following communications were read :— 
A New MEconopsis FROM YUNNAN. By Lieut.-Col. 
D. Prain, F.R.S. (Plate IT.) 
In a review of the known species of Meconopsis the writer 
has suggested (“ Ann. Bot.,” xx. p. 340) that our knowledge of 
the genus is probably still incomplete. The surmise thus 
offered has been very soon confirmed. To the kind courtesy 
of Professor bayley Balfour, F.R.S., the writer is indebted for 
an opportunity of examining the specimens belonging to this 
genus obtained by Mr. G. Forrest in South-Western China. 
Among these specimers there is material, collected in August 
1905, and accompanied by full field-notes, of a species hitherto 
undescribed. At the instance of Professor Balfour, Mr. R. M. 
Adam has prepared from this material the accompanying 
excellent illustration. Mr. Forrest speaks of the species as 
a magnificent but very local plant; he seems to have met 
with but one patch of it, two or three acres in extent, on a 
dry, barren, rock-strewn limestone ridge in the mountainous 
country which constitutes the Mekong-Salween divide, at 
12,000 to 13,000 feet above sea-level, somewhere between 
lat. 27° and 28° N. 
Though the material communicated is seanty, and does not 
include ripe fruits or seeds, the specimens and the accom- 
panying notes suflice to show that the species differs from 
all the hitherto known species of Meconopsis, and to indicate 
with accuracy its position and affinities. The closely set 
simple prickles which beset the leaves, stems, sepals, and 
ovaries place it at once in the group Aculeate of the section 
Eumeconopsis. The other members of this group are 
M. aculeata, Royle, the well-known prickly “Blue Poppy” 
of Kashmir; J. sinuata, Prain, the representative of 
M. aculeata in the Eastern Himalaya; I. rudis, Prain, the
