538 LXXXIX. SAPOTACE.E. (C. B. Clarke.) \_Sideroxylon. 



green, acute, shortly-acuminate, rhomboid at the base, primary nerves 12-15 on each 

 side ; petiole in. Calyx-lobes % in., oblong-lanceolate, villous. Corolla % in. and 

 upwards, segments acute, nearly glabrous. Stamens and staminodes as in 8. tomen- 

 tosum. Fruit (unripe) 1 by ^ in., acute upwards, glabrescent. This has been 

 supposed a var. of S. tomentosum, but the leaves are always acute ; none of the 

 numerous examples are spinescent.

MTS. of MALABAR and CEYLON ; from the Concan southwards ; common. PEGU and 

 MARTABAN (fide Kurz). 



A small or moderate-sized tree; branchlets woolly. Leaves 1-4| by f-2 in.; 

 tips obtuse or triangular, base cuneate, primary nerves 10-12 on each side; petiole 

 | in. Calyx-lobes in., oblong-lanceolate, woolly. Corolla in. and upwards, seg- 

 ments acute, nearly glabrous. Anthers oblong-lanceolate, exserted ; staminodes linear- 

 lanceolate. Berry f-1 by \-% in., ultimately smooth, yellow, 5-4- (or 3-1 -) seeded. 



IMPERFECTLY KNOWN SPECIES. 



8. S. ? GrAMBLEi, Clarke ; leaves elliptic acute, fruit H by in. ellipsoid narrowed 

 upwards 1-seeded. Chrysophyllum sp., Gamble ms. 



SIKKIM ; Kungbee, alt. 5000 ft., Gamble. 



A tree; shoots -minutely rusty- villous. Leaves 7 by 2f in., acuminate, base 

 rhomboid or broadly cuneate, mature glabrous, glossy beneath ; primary nerves 

 10-12 on each side, much raised beneath, secondary obscure; petiole 1 in. Pedicels 

 axillary, fascicled, in fruit % in. Calyx-lobes 5, (in fruit) in., ovate, obtuse, 

 minutely villous, deflexed. Corolla not seen. Fruit smooth, symmetric; exocarp 

 fleshy, small; endocarp, firm, rather thick, sinuously grooved without. Seed 

 conform to the fruit, albumen fleshy, a deep black-blue; embryo small. Almost 

 certainly belonging to this order; but the genus (while flowers are unknown) is 

 doubtful. 



4. ISONANiDRA, Wight. 



Trees. Leaves alternate, petioled, coriaceous, glabrous, primary nerves dis- 

 tinct. Floivers small, rusty or villous, in axillary clusters, subsessile or shortly 

 pedicelled. Calyx-segments 4, subequal, imbricated. Corolla deeply 4-lobed, 

 somewhat longer than the calyx. Stamens 8, all perfect, attached near the base 

 of the corolla, filaments short; anthers oblong-lanceolate, base sagittate; 

 staminodes 0. Ovary villous, 4-celled ; style linear. Berry ellipsoid, usually 

 1-seeded, flattened, smooth ; pericarp crustaceous. Testa hard shining, hilum 

 lateral, albumen fleshy; embryo large, cotyledons elliptic flat. Species 6, 

 in South India and Ceylon ; 1 in the Sandwich Islands. 



In the opinion of Thwaites and Beddome, who are well acquainted with this 

 genus in the field, all the Indian species of "Wight and A. DC. are varieties of one. 



1. I. villosa, Wight Ic. t. 360; leaves broadly elliptic rounded at both 

 ends glabrous, secondary nerves closely reticulated, flowers sessile on very short 

 thick lateral spurs. A. DC. Prodr. viii. 188. 



SOUTH DECCAN ; Quilon, Wight. 



Branches thick, obscurely rusty, scarcely pubescent at the tips. Leaves 2| by If 

 in., young glabrous, primary nerves in. apart; petiole ^ in., minutely rusty.
