Type in the U.S. National Herbarium, No. 1,145,291, col- 
lected on banks of the Yara River, Oriente, August 14, 1922 
(E. L. Ekman 14852). 
Related to R. calophylia Standley,* but evidently distinct 
in the small and narrow calyx-lobes. 
The type of R. calophylla was collected in the Sierra Maestra 
in July, 1922, by Brother Leon. Dr. Ekman also obtained it in 
August, 1922, at Arroyo Corojo, Nagua, Oriente (No. 14729). 
69. AN UNDESCRIBED SPECIES FROM HISPANIOLA 
Kallstroemia incana Rydberg, sp. nov. 
Kallstroemia caribaea Urban, Symb. Ant. 8:319. 1920. Not 
K. caribaea Rydberg, 1910. 
A diffusely branched herb, somewhat woody at the base; 
stems spreading, 2-3 dm. long, with coarser spreading and finer 
more appressed hairs, terete; stipules linear-oblong, 2-3 m 
long, tardily deciduous; leaves I-1.5 cm. long; petioles 2-3 oe, 
ng; leaflets mostly 3 pairs, obliquely ovate, EA 5 mm. long, 
hoary on both sides, acutish; peduncles 2-3 mm. long; sepals 
lance- ay acute, 3 mm. long; petals elliptic obovate, light 
yellow, 3 mm. long; fruit grayish-strigose, abou m. broad, 
t5m 
the beak 2 mm. long, conic at the base; carpels suites lees on 
the back and reticulate on the faces. 
Type collected at Barahona, Santo Domingo, July 1920, 
Fuertes 418 (herbarium of the New York Botanical Garden) ; 
also collected at Rincon, October 1911, Fuertes 1352. 
The two numbers cited were determined by Urban as K. 
caribaea and included under that name in his Flora Domingensis, 
but it differs in the hoary pubescence, the small leaflets, the small 
petals, scarcely half as long asin K. caribaea, the short peduncles 
and short beak on the small fruit. It approaches more K. curta 
Rydberg, from Curagao, with which it has the followingcharacters 
in common: small leaflets, short peduncles, small petals and 
fruit, and short beak; but it is more canescent, more branched, 
with shorterinternodes and smaller leaves, and the beak different, 
not at all swollen.
