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

 long. 



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



The nearest ally of this is D. binectariforum, Becld. from which 

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

 different disc, and minutely reticulate leaflets. 



Nat. Ord. Sapindacese. 



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 -1 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. Floivers '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. 



Sikkim Himalaya : Sir J. D. Hooker, at elevations of 11,000 to

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.
