Remarks on the Kaieteur Savannah. 239 
pretty dwarf shrub, a foot or eighteen inches high, with 
leathery oblanceolate glossy leaves, and small, clustered 
white flowers. It appears to vary much, and I gathered 
several of the forms. It proved to be a new and very 
interesting species of Simaruba, and Professor OLIVER 
has figured it in the /cones Plantarum, and named it 
S. monophylla. About the same part of the savannah, 
I found a new and showy flowered leguminous shrub of 
which, I regret, I failed to obtain seeds, the season being 
too early. It is referred approximately at Kew to the genus 
Dicymbe, which, so far, is only known by one species 
from Venezuela. It has pinnate 4-jugate leaves, terminal 
clusters of large, white, densely ciliate flowers, with long 
excerted stamens. 
More widely diffused over the savannah is a new species 
of Dimorphandra, which I still more appreciate as a 
subject for cultivation. It has a low spreading head 
of the habit of the well-known Poinciana regia, 
with densely flowered spikes of pinkish bloom, and all 
its parts except the upper surface of the little leaflets 
are covered with a bright brown silky pubescence. 
My visit was just in advance of its flowering season, but 
fortunately one tree was discovered in bloom before 
I left, and I likewise had the gratification, after many 
days' search, to find a couple of ripe pods, which 
produced good seed, from which I have raised plants. 
Some of the subjects which inhabit this savannah are ex- 
ceedingly rare, as well as geographically local, two or three 
of which I may mention. Over the Kaieteur there grew and 
bloomed in a fissure of the rock, the only tree I found 
of the beautiful white flowered Cosmibuena trfflora. I hesi-
