•15 in. thick. Seeds 3-angled, the posterior surface concave, 1*25 in. 

 long. 



On the banks of the Teesta in Sikkim, King. Cachar, Prazer. 



The nearest ally of this is D. hinectariforum, Bedd. from -which 

 however, it differs conspicuously in its much smaller flowers, totally 

 different disc, and minutely reticulate leaflets. 



Nat. Ord. Sapindaceae. 



Acer Papilio, n. spec. A small tree ; the young branches rusty- 

 tomentose at first but afterwards glabrous and with cinereous exfoliating 

 bark. Leaves simple, 5-lobed, the lobes caudate- acuminate and un- 

 equally serrate-lobulate ; the base in adult leaves sub-truncate to sub- 

 cordate, in the young leaves deeply cordate ; the upper surface glab- 

 rous except the puberulous middle nerve; the lower when young densely 

 covered with flexuose hairs deciduous with age except on the nerves, 

 the secondary nerves rather prominent beneath ; length 4 to 6 in., 

 breadth 4 to 4'5 in., petiole 3 to 4 in. Inflorescence a raceme-like ter- 

 minal or axillary rusty-tomentose panicle 3 or 4 in. long ; the branch- 

 lets cymose, 2-flowered, and about "35 in. long. Flowers "2 in. in diam., 

 on pedicels slightly longer than themselves. Sepals 5, oblong, sub- 

 obtuse, pubescent on the nerves and edges. Petals 5, oblanceolate-linear, 

 glabrous except the pubescent claw. Disk fleshy with 8 large and 

 2 small quadrate lobes. Stamens 8, inserted inside and between the 

 lobes of the disc ; anthers oblong, minutely warted ; the filaments 

 slightly flattened, glabrous. Ovary rusty-tomentose ; styles glabrous, 

 bifid. Fruit 1*25 in. in length and the same in breadth at the apex, the 

 wings obliquely and broadly rhomboid-triangular, the outer side of 

 each the longest and the inner the shortest, slightly puberulous and 

 with bold forking veins, the nucule about '3 in. in diam.

A species which has hitherto been confused with A. caudatum 

 Wall, and A. pectinatum, Wall, from both of which it is at once distin- 

 guished by its paniculate inflorescence — that of A, caudatum being 

 fasciculate, while that of A. pectinatum is a few-flowered simple raceme. 

 The wings of the samara of this are also broader than those of the other 

 two. The disc of the flower in this species has 8 large square lobes, 

 but at two points which stand opposite to each other the disc has a 

 fold in it, and hidden in each of these folds there lies a small lobe. 

 The disc is thus really 10-lobed, although at a superficial glance only 8 

 lobes are visible.
