220 MR. A. W. HILL ON THE 
Malva acaulis B. granatensis, and the other the Malva Purdiaei, Planch., which 
is now renamed Malvastrum purpureum, A. W. Hill. The specimen collected 
by Linden in New Granada, no. 1425 in Herb. Kew., does not belong to 
Malvastrum Purdiaei, A. Gray, but has been referred to a new species, 
M. Merida, А. W. Hill. 
M. purpureum is readily distinguished from M. Weberbaueri, which has 
similar fruits, by the usually glabrous character of its lamina and calyces 
and the deep purple colour of the flowers. The leaves are deeply lobed 
and the lobes bear numerous blunt finger-like lobulæ. The involucral bracts 
fall off early in this species, as appears to happen in M. oriastrum. М. pur- 
pureum shows no very marked affinity for any other species.

This species is very distinct in appearance owing to the velvety or dusty 
felt of minute stellate hairs which covers the leaves and gives the plants a 
yellowish ashen-grey colour. In addition to the finer tomentum, coarse 
strigose hairs are to be found on the petioles, and on the veins at the back 
of the lamina, as well as on the peduneles and calyces. The leaf-margin is 
slightly upturned. The flowers are described by Weberbauer as sulphur- 
yellow in colour.
