MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



On the pampas of Lake Rogagua, 1,000 feet, H. H. Rioshy, Oc- 

 tober 28, 1921 {no. 1366). "A large shrub, in copses, the flowers 

 white. ' ' 



On the 4th of October, the author collected at Rurrenabaque, 

 1,000 feet {no. 781), fruiting specimens of what appears to be 

 the same species. The leaves are somewhat larger, but in other 

 respects the same. The sessile fruit, in the dried state, is sub- 

 globose, and 2 cm. in diameter, blackish or deep-purple and 

 glabrous. 



TURNRRACEAE 



Piriqueta seticarpa 



Bristly-hairy, the hairs of the stem divergent and ferru- 

 ginous, the upper leaf-surfaces strigose, the lower pilose. Stems 

 a half-meter tall, sparingly branched, slender, terete, the 

 branches erect. Petioles 5 to 6 mm. long, stout, the glands not 

 apparent. Blades 3 to 5 cm. long, 2 to 3 cm. broad, oval-ovate 

 with rounded base and blunt summit, lightly sinuate-dentate, the 

 secondaries about 5 on a side, prominent beneath, strongly as- 

 cending and lightly curved. Pedicels slender, about half as long 

 as their leaves. Calyx broadly campanulate, o or 6 mm. long, 

 deeply parted, the lobes ovate, acute. Petals nearly a half 

 longer than the calyx, the stamens only about half the length of 

 the calyx. Ovary densely setose, chaffy, or scaly. Styles about 

 as long as the stamens, distinct, dilated at the summit, the ends 

 shortly and coarsely divided. Capsule 5 or 6 mm. long, and 

 about as broad, oval, appressed, pilose. 



On the pampas of Lake Rogagua, Rosario Hacienda, 1,000 

 feet, 0. E. White, November 2, 1921 {no. 1547). Species near P. 

 ovata (Bello) Urban. 



Turnera muricata 



Puberulent throughout except on the upper leaf-surfaces, 

 which are sparsely and minutely strigose and somewhat harsh, 

 though somewhat shining. Stems tall and rather stout, erect, 

 simple, terete, purplish-red. Petioles 5 or 6 mm. long, stout, 

 channeled above. Blades 5 to 12 cm. long, 2 to 3 cm. wide, lance- 

 oblong, acute, obtuse or barely acute at the base, very shallowly 

 dentate, thickish, the slender venation lightly prominent be- 

 neath, the secondaries about 7 to 9 on a side, strongly ascending.
