A few words regarding some of these endemic genera may not | 
be out of place. The Chlenacex are shrubs or trees, of which 
there are at present known 24 species comprised under 7 genera. 
The majority of the plants are found in Eastern Madagascar, all 
the Rhodolena entirely so. The only species of Sclerolena 
(S. Richardi) is found in the north and north-west, and the four : - 
species of Xerochlamys in the central, parts of the island. X. pi- 
losa and X. pubescens are low wiry shrubs found on some of the 
hills and mountains of the interior, and are used by the natives 
in ihe manufacture of rum, but are said to cause vomiting of 
blood if used incautiously. They are known as “ Hatsikana." 
Four of the species of Leptolena occur in the large eastern forest, 
though L. multiflora is found also in the north-west part of the 
island, where Z. cuspidata finds its home. Leptolena pauciflora 
is a hard-wooded tree, from the trunk and branches of which, at a 
certain season of the year, there is a ceaseless dropping of water, 
sufficient indeed to keep the ground quite damp. This is caused 
by a number of hemipterous insects crowding together in a slimy 
liquid. May this afford an explanation of the similar well-known 
phenomenon exhibited by the Tamai-caspì, or Rain-tree, of the 
Eastern Peruvian Andes? The various species of Rhodolæna, 
which, with the exception of R. altivola, a semi-scandent shrub , 
are large trees, have handsome bright purple flowers about 2 
inches in diameter; and Sarcolena grandiflora, a tree found on 
the east, and probably also on the north-west, coast, possesses a 
white flower, also about 2 inches in diameter. Cheirolena linearis
