Arr. IX. Descriptions of Three New Genera of plants, fi hee 
State of New York. Cylactis, Nemopanthis, and Polanisia,— by 
C. S. Rarinesave. ’ 
1. N. G. Cylactis. * 
Curyx campanulated 6 ‘to 10 fidus, sepals a little ‘unequal. * 
Petals 4 to 6 equal. Many perigynous stamens. Pistils 8 to 
12, ovaries sessile ovate, styles elongated, stiginadcapitatad 
Berries few, distinct, one seeded. 
‘This new genus belongs in the analytical and natural me- 
thod, (see Analysis of Nature) to the first natural class Eltro- 
gynia, first natural order Rhodanthia, second natural Sa: 
Senticosia, next to the genera Rubus, Oligacis, &c. It w 
range itself into the artificial class Icosandria of the EGbcen 
sexual system; but not properly into any of its orders, since 
the number of pistils is variable, and never above 12. Only 
one species belongs to it, which I have discovered in company 
with Mr. Knevels, on the Catskill mountains. The etymology 
of the name derives from two Greek words meaning radiated 
‘culyx. It differs essentially from Rubus by the unequal many 
cleft calyx, variable petals, and few pistils. 
Cyluctis montana. Mountain cylactis—Stem herbaceous up- 
right, unarmed, pubescent ; leaves quinate, nearly s 
upper ones sessile, stipules oblong, folioles ovate acuminate, 
incised, serrated, ciliated, base acute, entire, the middle one 
petiofated : flowers few corymbose, peduncles erect elongated 
bracteolated ; calyx pubescent, sepals lanceolate acute, 
nerved, reflexed; petals cuneate-obovate, longer than the 
calyx. 
It is a small perennial plant, rising about half a foot; flowers 
white, blossoming in June. On the Catskill mountains near 
the great falls, &c. :
