636 LXVI. BEGONIACE.E. (C. B. Clarke.) [Begonia. 



thick, succulent, equally 2-par%te ; styles 4, 2-fid nearly from the base, stigmas 

 winding spirally with 3 turns. Fruit ^-f in. diam pendent ; walls very thick, suc- 

 culent, indehiscent or finally dehiscent at the angles. Seeds shortly ellipsoid, some- 

 what obovoid. Cathcart Ic. Ined. represents the cells of the ovary as occasionally 

 3 which is not improbable,^ his artist may have confounded B. Candollei (No. 4) 

 with the present species. 



2. B. silhetensis, C. B. Clarke; stemless, inflorescence shorter than 

 the petioles, leaves ovate finely denticulate hardly serrate or lobed, fruit globose 

 thick-walled 4-celled densely covered with shaggy brown hair. B. gigantea,

 CACHAR; Keenan. 



Eootstock short, thick, fibrous on all sides, scarcely tuberous. Leaves 6 in., 

 broadly ovate, not acuminate, shaggy on both surfaces in Griffith's examples, only 

 slightly hairy in Wallich's. Petiole 6-18 in., hirsute in Griffith's examples, less 

 hairy in Wallich's. Scapes 2-4 in., 1-7-flowered. MALE : sepals 2, hairy without, 

 ^ in. in Griffith's examples, smaller nearly glabrous in Wallich's ; petals 2, smaller 

 than the sepals, glabrous; stamens numerous, shortly monadelphous, anthers nar- 

 rowly oblong. FEMALE : styles bifid with tortuose stigmas. Fruit in. and 

 upwards in diam., globose or ovoid, without angles or protuberances. Seeds many, 

 shining brown, shortly ellipsoid. Griffith's No. 2569 (with which Wallich's No. 3677 

 B agrees), differs considerably in hairiness and in size of the flower from Wallich/s 

 No. 9107 on which A. DC. founded his Casparyal silhetensis: two species are pos- 

 sibly here mixed, but the material is not sufficient to justify a new species. 



3. B. tessaricarpa, C. B. Clarke ; nearly stemless, inflorescence much 

 shorter than the petioles, leaves ovate nearly glabrous sinuate-denticulate hardly 

 serrate, fruit subpyramidal 4-celled laxly hairy, carpels acutely keeled and 

 ending upwards in a short linear patent horn. 



ASSAM ; Griffith (Kew Distrib. No. 2586). 



Creeping stem 0-2 in. Leaves 2-4 in., broadly ovate, glabrous or minutely pu- 

 bescent on the nerves beneath; petiole 6-12 in., pubescent upwards. Inflorescence 

 2-4 in. Flowers much smaller and fruit less succulent than in B. Eoxbiirghii. Fruit 

 about | in. diam., slightly pubescent. This solitary example may be possibly a 

 stunted example of B. Eoxburghii, from which it does not differ in any essential 

 particular though it is very unlike it in general aspect ; the seeds are alike. 



4. B. inflata, C. B. Clarke ; stem, lengthened, inflorescence axillary, 

 leaves oblong-lanceolate glabrous or nearly so sinuate-dentate scarcely serrate, 

 fruit 3-celled. 



DARJEELING, alt. 3000 ft.; C. B. Clarke. BHOTAN? Griffith (Kew Distrib. No. 

 2587). 



Erect, 3-4 ft., branched. Leaves 4 by l-l in., acuminate, very unequally 

 cordate ; petiole -f in. ; stipules lanceolate-subulate, glabrous. ^Flowers in short 

 axillary dichotomous cymes from several axils on each branch ; bracts lanceolate- 

 subulate. MALE : sepals 2, white, obovate, glabrous ; petals 2, linear-obovate ; sta- 

 mens about 50, scarcely monadelphous ; anthers narrow-oblong; connective produced, 

 obtuse. FEMALE : perianth of 4 segments ; ovary 3-celled, placentas 2-fid. Fruit 

 f in. diam., trigonous or almost triquetrous; carpels round, as it were inflated, with 

 a narrow line down the back, glabrous or nearly so, indehiscent or probably at 

 length dehiscing down the ridges as in E. Eoxburghii. Seeds short, ellipsoid some- 

 what obovoid. Griffith's examples are in good fruit but the locality is doubtful : his 

 ticket is marked " Umb. ascent. 4 day."
