long. Stamens 4 ; (in all 4) cells of anthers 2, oblong, muticous, parallel, 
one slightly lower, with a row of papille fringing the slit (as usual in 
Lu-Lepidagathis) ; pollen small, tetrahedral, smooth with very slender

The pollen is remote from anything seen in Lepidagathis ; I have examined it in 
5 or 6 flowers and believe it to be abnormal, sterile. [ have found one or two grains 
not unlike the pollen of the preceding species. 
12. L. perglabra, (. B. Clarke. Very glabrous, margins of the 
floral leaves with a few white long hairs. Branch 20 in. long, divided, 
very straight. Leaves 3} by } in., 3-nerved, with transverse cystoliths 
on the upper surface. Heads numerous, scattered, axillary in the upper

This is totally different from the otber part of Schweinfurth, 4076, in Herb. Kew.

two plants arrived at Kew. The present plant bas very young heads, but is very
