THE SPECIES OF HEDYCHIUM. 367 
flowers of that species. It is no doubt allied to it, but easily dis- 
tinguished by the acute leaves, which are strongly pinnate-nerved, 
almost snow-white, and closely tomentose beneath. It appears also 
very nearly allied to R. longifolium. 
Leaves 5-6 inches long, by about 2 inches wide, of a bright green 
above, and only puberulous in the young state before expansion. Sti- 
pules oblong, concave, abruptly apiculated, puberulous. It appears to 
be a scarce species in the localities yet visited. The flowers and fruit 
are not yet known with certainty, but will probably approach to R. 
Hodgsoni. 
Mr. Booth obtained only a solitary living plant, and no seeds or 
flowers. "Two or three plants of this species appear, however, to have 
come up with the seeds of R. longifolium. 
I have dedicated this species to the celebrated Asiatic botanist, 
Blume.

All the parts of the plant, leaves, bracts, calyx, and corolla, even the 
filament, are marked with copious minute, globular, brown, and semi- 
pellucid glandular dots, visible only under the microscope; more par- 
ticularly the parts of the flower. This punctuation exists in a greater 
or less degree in most if not all the species. I have before me a large
