112 XXVII. SAPINDACE7E. [Acer. 



Buds glabrous, young leaves with a few scattered hairs. Leaves pale 

 beneath, cordate, 5-lobed, the 2 outer lobes small, with 5 basal nerves, 

 all, or the 3 inner penni veined, margin with large obtuse serratures, peti- 

 oles exceeding half the length of leaf. Flowers pentamerous, appearing 

 after the leaves, in terminal corymbose panicles. Nuts unevenly gibbous, 

 wings erect or divergent, back slightly curved. (A. sterculiaceum, Wall. 

 PI. As. rar. t. 105, from Nepal, is similar, but the male flowers are repre- 

 sented in lateral racemes below the insertion of the leaves.) 



North-West Himalaya, from the Indus to Nepal, between 4000 and 10,000 ft., 

 scattered in mixed forests, mostly in shady valleys. Fl. Apr. ; fruit ripens Oct. 



A large tree, 70-80 ft., with a tall straight trunk 12-13 ft. in girth, and a 

 large oval, close crown. Twigs laterally compressed, red or bluish, smooth, with 

 some callous dots, bark of trunk dark ash-coloured, or pale-brownish white, with 

 thin long irregular scales. Wood of pale cream-colour, with brown bands, 

 porous, soft, light, medullary rays indistinct. Some of the inferior kinds of the 

 Tibetan drinking-cups are made of it. 



6. A. caudatum, Wall. PL As. rar. t. 132. Vern. Khdnsing, Nepal. 



Young shoots pubescent. Leaves 5-lobed, the 2 outer lobes small; 

 lobes long -acuminate ; base truncate or subcordate, margin divided into 

 deep sharp cuspidate serratures ; basal nerves 5, the 3 inner penniveined. 

 Petioles reddish, pubescent, longer than half the leaf. Flowers appearing 

 soon after the leaves in lateral and terminal short glabrous racemes, fre- 

 quently tetramerous. Sepals ovate-oblong, with 6 nerves. Petals white, 

 clawed. Disc fleshy, stamens 4-6, in male flowers much longer than calyx. 

 Racemes elongated in fruit ; wings pink, erect, or divergent, inner edge 

 frequently denticulate. 



Himalaya, at high elevations (8000-11,000 ft.), from the Chenab to Nepal. 

 Fl. March, April. A large-sized tree with dark-brown bark. 



A. pectinatum, Wall., with divaricate wings, is probably only a variety. A. 

 argutum, Maximowicz, from Japan, is nearly allied.

 or 7-lobed, from truncate or subcordate base ; lobes long-acuminate, se- 

 parated by rounded sinus, margin entire ; basal nerves 5-7, the inner 

 penniveined, with fine reticulation between. Petiole longer than leaf. 

 Flowers appearing with or after the leaves on long filiform pedicels, in 

 lateral and terminal stalked corymbs, pentamerous, glabrous ; male and 

 bisexual flowers on the same branch. Sepals oblong. Petals spathulate.
