and Sylva, iii. 191) and by Hemsley (Bot. Mag., t. 8027) that this species is 
distinct from M. integrifolia. In the correspondence which has taken place 
regarding this plant. Dr. Fischer de Waldheim has invited the writer to 
name and describe the species. It is dealt with below as M. pseudo - 
integrifolia (PL XXV). 
In 1905 Messrs. James Veitch and Sons kindly allowed the writer to 
examine the fine collection of Meconopsis made for them in south-western 
China by Mr. E. H. Wilson. This collection contained ample material of 
M. chelidonifolia , Bur. and Franch., and of M. Oliveriana , Franch. and 
Prain, two species that as regards their fruits are very distinct, but that in 
all other respects are puzzlingly alike. It is now certain that the flowers of 
M. Oliveriana are yellow, as they are in M. chelidonifolia , not purplish, as 
the writer in 1895 was inclined to believe. Another interesting fact brought 
out by this collection is that M. Wallichii , the blue Sikkim Poppy, extends 
to, or at all events reappears in, Szechuen. The collection also contains 
fuller material of M. Henrici , Bur. and Franch., a species described in 1891, 
which has this year (1906) flowered with Messrs. Veitch at Coombe Wood. 
A question has arisen with regard to this species which cannot for the 
moment be definitely settled, but which illustrates the difficulties that are 
encountered in dealing with species of this genus. In 1876 Maximowicz 
described for the first time the form known in gardens as M. racemosa . 
The writer has already (Journ. As. Soc. Beng., lxiv. 2, 314) shown that we 
have reason to believe that M. racemosa is only a form of M. horridula with 
agglutinated instead of discrete scapes. An opportunity since 1895 of 
examining both forms as they grow, side by side, in southern Tibet has 
tended to confirm the writer in this opinion. Though it probably will be 
convenient in horticulture to continue the use of the name M. racemosa , 
there is hardly room for doubt that M. racemosa and M. horridida are 
conspecific. In 1886 Franchet described as a Cathcartia the Meconopsis 
lancifolia (group Primulinae ) of this paper, a species which, like M. racemosa 
among the Aculeatae , has flowers in raceme-like cymes without bracts sub - 
tending the individual flowers. Now that fruiting specimens of M. Henrici 
are available it is found that its capsules are quite like those of M. lancifolia , 
and there is room for suspicion that M. lancifolia from Yunnan may bear 
to M. Henrici from Szechuen somewhat of the relationship that M. racemosa 
bears to M. horridula . 
The receipt of further material of the plant, which in 1895 the writer 
dealt with as M. sinuata , var. Prattii , shows that it is not referable to 
M. sinuata. In M. sinuata there are 4 petals and the capsule is very like 
that of M. Henrici , whereas the form in question has 5-8 petals, and has 
a fruit more like that of M. acideata and M. horridula , but smaller than in 
either of these species. It now appears that M. sinuata , var. Prattii, from 
Szechuen is identical with a plant from Yunnan which the writer treated as
