5. B. Dux, C. JB. Clarke; stem lengthened, inflorescence axillary not 

 diffuse, leaves ovate with scattered hairs above driiii e-what cili 



MOULMEIN ; Moolee alt. 6000 ft. ; Parish. 



Stem exceeding a foot, succulent, tubercular. Leaves in., acuminate, much 

 auricled on one side at the base, somewhat angular, pubescent on the nerves 

 beneath; petiole 4 in., pubescent upwards; stipules f in., ovate-lanovolate, gl 

 persistent. Flowers (all male in the solitary example) large, glabrous, in short few- 

 flowered cymes with bracts resembling the stipules. Sepals 2, round ; petals' 2,* nar- 

 rower. Stamens very many, shortly monadelphous ; anthers narrow-oblong ; connec- 

 tive hardly produced. The section is doubtful, the female flowers being unknown : 

 it may be a Platy centrum: Parish remarks that it looks like B. Eex; but the thick 

 erect tall stem differs. 



SECT. II. Alaecida. Fruit triquetrous, faces with a medial line ; carpels 

 dehiscing dorsally, angles with short subequal wings below the middle ; placentas 

 divided. Small small-flowered plants ; filaments monadelphous ; styles connate. 



6. B. alaecida, C. S. Clarke-, stem branched, cymes elongate subpro- 

 liferous laxly pubescent, fruit inflated glandular-pubescent. 



MOULMEIN; Parish. 



Eooistock small, fibrous. Stem 3 in., nearly glabrous. Leaves l^-4 in. 

 diam., cordate, round, minutely denticulate, puberulous-punctate above, nearly 

 glabrous beneath ; petiole l-2 in. ; stipules ovate, acute, minute. Cymes 3-6 in., 

 weak, somewhat panicled ; bracts small, ovate, persistent, with lax hairs. MALE : 

 sepals 2, round ; petals 2, narrow-oblong ; stamens not very many ; anthers very 

 short, obovoid ; connective not produced. FEMALE : styles united a long way, stigmas 

 lunate ; ovary with glandular hairs. Capsule scarcely 5- in. broad including the 

 wings, ripe green, with 6 lines equally diverging from the base of the styles. 

 Seeds short, ellipsoid. 



7. B. tricuspidata, C. B. Clarke ; stem short or 0, leaves ovate crenate 

 puberulous on the nerves beneath, scape pubescent, capsule stellately tri- 

 cuspidate glabrous. 



MOULMEIN; Parish. 



Eootstock small, fibrous. Stem sometimes 1-2 in., pubescent. Leaves round or 

 ovate, somewhat cordate, crenate or nearly entire, with scattered minute hairs above ; 

 petiole 5-! in., pubescent; stipules minute. Cymes 2-3 in., minutely pubescent; 

 bracts ovate, minute. MALE : sepals 2, obovate ; petals 2, narrowly obovate ; stamens 

 not many ; anthers very short, ovoid ; connective not produced. FEMALE : perianth of 

 4 segments, much as in the male: styles combined below, each with two curved 

 branches. Capsule less than ^ in. broad including the wings, with six lines equally 

 diverging from the base of the styles, wings acute. Seeds very small, shortly 

 ellipsoid. 



8. B. triradiata, C. B. Clarke ; stem short or 0, leaves ovate serrate or 

 doubly crenate glabrous and white beneath, scape glabrous, capsule stellately 

 3-rayed glabrous. 



MOULMEIN; Parish. 



Eootstock a small cluster of tubers. Stem 0- in., glabrous. Leaves f-l in., 

 somewhat cordate, incise-crenate, minutely pilose above; petiole |-f in., glabrous; 

 stipules small, lanceolate. Cymes 2-3 in., glabrous; bracts small, lanceolate, gla- 

 brous, persistent ; flowers pink. Flowers fruit and seeds closely resembling those of 

 B. tricuspidata. 



SECT. III. XLnesebeckia. Capsule 3-celled, triquetrous, the angles pro- 

 duced into three often unequal papery wings ; faces flat with a rib or line down
