herb, with habit quite peculiar, next to Lepa- 

 dena by glands opposite, but habit totaly unlike 

 and perianthe not 8(id, Zalitea was an ancient 

 name of this family or Polygonum. 



991. Zalitea linearis II. stem grooved 

 2-3chotome, leaves remote oppos. petiolate, 

 linear, base acute, end mucronate, flowers sub- 

 sessile, solitary in dichotomies and axils — an- 

 nual smooth plant, erect ? but weak, subpedal, 

 leaves distant uncial, not obliqual, flowers small 

 green with 5 ovate segments, acute which is 

 unusual in this tribe, inner glands yellowish lun- 

 ulate, ends obtuse concavity beneath. Seeds 

 not seen but probably as in Lepadena. It grows 

 on Red River of Louisiana,collected by Binder 



992. APLARINA Raf dioical and monoi- 

 cal, perianthes uniflore, male perianthe tubular, 

 minutely 41obe at top, lobes unequal ovate sub- 

 serrate, a single stamen exerted borne upon a 

 terete androphore, rudiments of some sterile. 

 Female perianthe campanulate 81obe,lobes sub- 

 entire 4 alterne shorter. Capsule villose, stig- 

 mas 3 bilobe. Habit of Xamesyke. — Another 

 G. remarkable by declinity and different peri- 

 anthes, the male uniflore or monandrous. The 

 name means simple stamen. There are many 

 sp. of this G, blended in Euphorbia, I have late- 

 ly noticed that E. hypericifolia probably be- 

 long to it. 



993. Aplarina prostrata Raf. prostrate pp- 

 bescent, stems terete, dichotome, leaves petio- 

 late obliqual ovatoblong acute, subserrate ; flow- 

 ers in axils solitary subsessile — annual, laying 

 flat on the sand where it grows in Pennsylvania, 

 blended by myself with the akin G, until the 

 flowers well examined, and perhaps other sp. 

 belonsf also here. Several stems 3 to 6 inches
