MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



Rurrenabaqiie, 1,000 feet, M. Cardenas, November 24, 1921, 

 (no. 1773). Fruiting specimens collected by the author in May, 

 1886, in Mapiri, 2,500 feet, Parke, Davis & Co. {no. 2620), and by 

 M. Bang, in December, 1892, between Tipuani and Guanai {no. 

 1684), apparently belong to this species. The mature fruits are 

 on spreading pedicels, 5 to 7 mm. long, and are 1.5 cm. broad, 8 

 mm. long and nearly as thick, transversely elliptical, dark-green 

 and glabrous. 



Faramea tenuifolia 



(Fruiting specimen.) Glabrous. Branchlets elongate, slen- 

 der, nerved, or the younger narrowly angled. Stipules connate, 

 broader than long, papillose, aristate, the awns elongating, at 

 length 4 or 5 mm. long, l^etioles divaricate, 1 cm. long, includ- 

 ing the abruptly produced base of the leaf, margined. Blades 

 to 1 or even 1.5 dm. long, and 5 cm. broad, oblong or oval, with 

 the base abruptly contracted into the petiole and an abruptly 

 short-pointed and obtuse summit, thin. Cymes terminating the 

 branchlets, slenderly peduncled, mostly simple and small, with 

 mostly about 5 fruits. Pedicels very slender, 4 or 5 mm. long. 

 Mature fruits about 6 mm. broad and 5 mm. high, bearing the 

 shortly toothed calyx-limb, which is about 1.5 nmi. broad, and 

 surrounds the concave style base, the surface of the fruit being 

 densley papillose or muricate. This is the only Bolivian species 

 with muricate fruit that I have seen, but it is evidently quite 

 distinct from F. salicifolia. 



Rurrenabaque, 1,000 feet, M. Cardenas, January 21, 1922 

 {no. 2048). 



Diodia rogaguana 



Gray-hispid, with short divergent hairs, the stems elongate, 

 stout, quadrangular. Stipules very unequal, filiform, rigid, 

 pilose. Leaves sessile, 1.5 to 2.5 cm. long, 5 to 12 mm. broad, 

 lanceolate to oblanceolate, obtuse or acutish, thickish, 5- to 7- 

 ribbed, the ribs consisting of stout, rough-hairy secondaries, 

 which are impressed above, very prominent beneath. Axillary 

 whorls several- to many-flowered, the flowers closely sessile. 

 Calyx-tube hemispheric, in flower shorter, in fruit longer than 

 the four linear, thick, obtuse erect lobes. Corolla about as long 

 as the calyx, the tube campanulate. Stamens exserted, incurved, 

 the anthers short. Style exserted, bifid, the branches somewhat 

 unequal. Fruit 2.5 mm. long and nearly as broad.
