8. XL. platycarpa, Am. PugUl. 26 ; hirsute or glabrate, leaves ovate 

 linear-oblong -ovate or -lanceolate, stipular bristles many hairy, cymes with 

 short crowded branches but lengthening much in fruit, mericarps dorsally flat- 

 tened and deeply keeled. 



Ceylon ; abundant in the central province, alt. 4-7000 ft. 



According to Thwaites a very variable species, of which he distinguishes the three 

 following forms, which look very unlike ; all have short branched cymes and two 

 forms of flowers, which are either hirsute glabrate or glabrous, and resemble those of 

 K. zeylanica, but are often larger. 



Vab. 1. platycarpa, Arn. 1. c. ; nearly glabrous, branches with two obscure lines 

 of pubescence, leaves narrowly oblong-lanceolate ciliolate, stipular bristles short nearly 

 glabrous. — Eesembles in foliage K. eeylanica, and as the cyme branches frequently 

 run out I suspect these species may prove the same. 



Vab. 2. hirsitta,'S\xw. Enum. 152; hirsute or tomentose, leaves broader, stipular 

 bristles longer and liirsute, cymes very dense, flowers larger usually very hirsute. — 

 K. hirsuta. Am. I. c. 



Vae. 3. foliosa, Thw. 1. c. ; hirsute or glabrate, branches very stout, leaves more 

 coriaceous broadly ovate, stipular bristles very rigid, large calycine lobe sopietimes 

 foliaceous. 



DOTJBTFDI, SPECIES. 



K. STJMATBENSis, DO. Frodr. iv. 569, from the Circars ; — it is impossible to say to 

 what this refers. Roxburgh's Spermacoce mmatrensis (which is referred to it) is 

 described as having the corolla with a broad gibbous tube, and a 2-valved capsule 

 2-partible from the base ; it is probably a Hedyotis.

62. OCTOTROFIS, Bedd. 



A glabrous shrub; branches slender. Leaves elliptic-lanceolate, caudate- 

 acuminate, membranous ; stipules triangular, persistent. Flowers in pedunoled 

 axiUary or supra-axiUary corymbose cymes. Calyx-tuhe turbinate, 5-toothed. 

 Corolla eampanulate, tube short, throat villous ; lobes 5, ovate, acute, twisted 

 in bud. Anthers 6, sessile on the mouth of the corolla, linear, cuspidate, base 

 2-fid, exserted. Dish small. Ovary 1-celled ; style stout, pubescent, 8-ribbed ; 

 arms 2, short, acute, glabrous ; ovules solitary or a pair pendulous from the top 

 of the cell. Fruit ovoid, smooth, coriaceous, 1-seeded. Seed oblong, pendu-. 

 lous. 



1. O. travaucorica, Beddome Fl. Sylv. t. 327 ; For. Man. 134/12, 



Tbavancoee, alt. 3-3500 ft. ; Shevagherry hills, Wight, Beddome. 



Leaves 3^-6 in. ; petiole \ in. Peduncles capillary, half as long as the leaves ; 

 cyme-branches opposite ; bracts small; flowers \ in. diam., shortly pedicelled, 2-brac- 

 teolate. — A very singular genus, belonging to an otherwise exclusively African tribe. 

 Octotropis is further unique in the Order, in having a 1-celled ovary with 1 or 2 pen- 

 dulous ovules. Specimens of this in Wight's Herbarium are fastened on a sheet with 

 a Canthiimi.

 posite; stipules connate. Flowers small, axillary, fascicled or in peduncled 

 corymbose cymes, white or greenish, sometimes polygamous, Cali/.r-tube short ;
