covered with extremely dense soft hairs, at least 1 line long, in 
which respect it is notably at variance with the preceding spe- 
cies. In one of Sagot’s specimens the leaves are 8^ inches long, 
7^ inehes broad, on a petiole 4^ inches long; in the other they 
are 9| inches long, 5 inches broad, on a petiole 3^ inches long. 
The upper surface of the leaves is glabrous, and hollowed in 
broad channels along the lines of the nerves and transverse 
veins, which are clothed with reddish hairs ; the intermediate 
basal nerves are widely divaricated at a medium angle of 45° 
with the midrib ; five or six lateral nerves spring from the mid- 
rib, the first at a distance of only 1 1 inch from the base ; beneath, 
the leaves are ferrugineo-pilose (not tomentose), and the petiole 
is thickly covered with long, spreading, ferruginous hairs. The 
raceme is 7 inches long, and its numerous 1-flowered pedicels 
are 6-8 lines long.

The above diagnosis is formed upon an examination of a 
flowerless specimen named by M. Triana himself : it is certainly 
distinct from AublePs plant, and is stated by him and Dr. Plan- 
chon to be identical with that from which DeCandolle derived 
the character of his Abuta rufescens, a plant still preserved in 
the Paris herbarium. It is distinguished by its much smaller 
leaves, which are oval, not cordate, clothed with cinereous (not 
reddish) pubescence, by its flowers being covered with adpressed 
silky hairs. They also pronounce the two plants just mentioned 
to be identical with the original specimen of Cocculus Martii, 
St. Hil. & Tub, collected in Kio de Janeiro by Guillemin. The 
correctness of this identification may be questioned, not only on 
account of the great distance of their loealities, but because, of 
the two plants collected there by Guillemin, one corresponds 
with my Abuta heterophylla, the other with my A. macrophylla.
