This species at first sight might be regarded as a variety of 

 P. granclifolia BL, but the male flowers, even without the use of 

 a lens, are evidently quite different. 



Specific name from the broad appendage of the male perianth- 

 segments. 



Pilea troyensis. Herba monoica, caulibus repentibus, pube- 

 rulis. Folia ejusdem paris magis minusve ingequalia, late ovata 

 aut saepe rotundata, ultra trientem inferiorem crenato-serrata, vel 

 interdum fere integerrima, trinervia, utrinque pellucidis pilis 

 sparsis induta, infra nervis strigilloso-puberula, membranacea ; 

 cystolithi lineares, infra minores. StijmlcB brevissimge, rotundatae.

Hab. — Eocky wooded hill, Troy, Britton, 708 ! 



Leaves -5-1 cm. 1., •5--9 cm. br., with the two lateral nerves 

 produced to one-half or three-fom'ths of their length ; petioles 

 1-2-5 mm. 1. Stipules about -5 mm. 1. Peduncles glabrescent, 

 5-7 mm. 1. Male flowers subsessile ; perianth globulose, with a 

 few pellucid hairs, about -5 mm. 1. ; dorsal appendages, those of a 

 pair equal, one pair bluntly and shortly triangular, the other linear, 

 blunt. Female floiver about -5 mm. 1., larger segment -4 mm. 1., 

 the lateral about half the length. Achene (unripe) white with 

 orange-red stigma, about -5 mm. 1. 



This species is very near P. Harrisii Urban {Symbolce Antil- 

 lance, i. 299), but differs in the flowers.
