316 LI. ROSACES. (J. D. Hooker.) [Prunus. 



A small nearly glabrous tree, with young parts sparingly pubescent. Leaves very 

 variable, 4-6 in., usually oblong-lanceolate with a cordate base, serratures often 

 double very close-set; nerves often with hairs in the axils beneath, under-surface not 

 glaucous ; nerves spreading, slightly arched ; petiole -1 in., slender, glands small or 

 ; stipules linear, membranous, caducous. Racemes from the axils of fallen leaves or 

 terminating lateral leaf-branchlets, 4-10 in. long, drooping; peduncle and rachis gla- 

 brous pubescent or tomentose ; pedicels in. ; bracts linear, caducous. Flowers white. 

 Calyx-tube hemispheric or turbinate ; lobes rounded, obtuse, gland-toothed. Petals 

 orbicular, concave. Drupe acid, the size of a large pea ; stone thick, rugged, Wal- 

 lich's name of cornuta alludes to a diseased (by insects) condition of the ovary, which 

 becomes elongate curved and fusiform as in P. Puddum. Foliage red in autumn. 



9. P. nepalensis, Ser. in DC. Prodr. ii. 540 (Cerasus) ; leaves lanceo- 

 late or oblong-lanceolate acuminate crenate-serrate glaucous "beneath, nerves 

 16-20 pairs, base usually acute, petiole eglandular, racemes elongate, drupe 

 globose, stone smooth in. diam. Cerasus glaucifolia, Wall. Cat. 717. C. Lind- 

 leyana, Wall. Cat. 1008. 



Temperate Himalaya, from KTJUMAON, alt. 6000 ft. to SIKKIM alt. 7-10.000 ft. 

 KHASIA MTS., alt. 4-6000 ft. 



Very difficult to distinguish from P. Padus except by the fruit, which is more 

 than twice as large, with a quite smooth thick- walled stone ; leaves \isually glaucous 

 beneath and acute at the base, serratures far less sharp and more distant ; calyx 

 lobes shorter. 



10. P. undulata, Ham. in Don Prodr. 239 ; leaves membranous ob- 

 long-lanceolate acuminate crenate-serrate glabrous, nerves 6-10 pair, petiole 

 usually eglandular, racemes slender, flowers in. diam., stamens 15-20, drupe 

 globose pointed, stone smooth \ in. P. adenophylla, Wall. MSS. Cerasus un- 

 dulata, Ser. MS$. in DC. Prodr.ii. 540. C. capricida, Wall. Cat. 718. 



Temperate Himalaya from KTTMAON alt. 6-8000 ft. to SIKKIM alt. 8-12,000 ft., 

 and BHOTAN. KHASIA MTS., Griffith. 



Branches slender, quite glabrous. Leaves variable, usually 2-3 in., oblong- 

 lanceolate but often larger and almost linear-lanceolate, base acute or rounded, mem- 

 branous and undulate when dry ; nerves 8-10 pair, slender, spreading and arched ; 

 glands or 1 or 2 at the base of the leaf, rarely on the slender petioles. Racemes 

 usually more slender than in the two preceding species, glabrous or puberulous. 

 Flowers white. Calyx-tube glabrous, lobes glabrous or ciliate. Stamens short. Drupe 

 with a thin-walled smooth stone. Foliage of this is often like that of P. nepalensis, 

 but has usually fewer veins, and the small flowers and drupes well distinguish it 

 Wallich observes that the foliage is poisonous to goats. 



* Foliage persistent. 



11. P. martabanica, Wall. Cat. 4902 (Cerasus ?) ; glabrous except the 

 pubescent racemes, leaves oblong-lanceolate caudate-acuminate quite entire 

 smooth, nerves very faint, racemes fascicled stout short, petals small orbicular, 

 stamens very numerous. Kurz, For. Flor. Brit. Burm. i. 434. 



Eastern Peninsula ; MABTABAN, Wallich ; MERGUI, Griffith ; ANDAMAN and TE- 



NASSERIM, KUTZ. 



Branchlets quite glabrous. Leaves 5-7 in. long, coriaceous, very smooth on both 

 surfaces, shining above, base rounded ; nerves 6-8 pair, arched, very slender ; petiole 

 - in., slender, eglandular. Racemes 1-7 in., usually on the old wood ; peduncle and 

 rachis strict ; pedicels in., stout. Flowers in. diam. Calyx-tube obconic, coria- 

 ceous ; lobes erect, ovate, obtuse. Petals small, orbicular. Stamens 60-80 in many 

 series. Ovary glabrous, style long, exserted ; Drupe 1 in. long, cylindric oblong, 

 pointed, apparently dry ; stone thin- walled, smooth. Foliage like that of P. Java-
