NEW PLANTS FROM JAMAICA 179 



apparently tougher, not serrate so far down, and with much more 

 obvious cystoUths ; inflorescence with few flowers, not paniculate ; 

 perianth-segments of the female flower subequal. 



Pilea oblanceolata. Herba dioica (?) (floribus femineis tan- 

 tum visis), glabra, caulibus decumbentibus vel ascendentibus, 

 simplicibus. Folia ejusdem paris magis minusve aequalia, ob- 

 lanceolata, acuta vel breviter acuminata, basi longe attenuata, 

 3-6 cm. 1., apice serrata, triplinervia, membranacea, cystolithis 

 supra linearibus, infra obsoletis, minutis inspersa. Cymes femineae 

 paniculatge densiflorse, pedunculis petiolis longioribus. Type in 

 Herb. N. York Bot. Gard. 



Stems 10-30 cm. 1., rooting below at the nodes, and between the 

 nodes, when dry, more or less compressed, 1-5-3 mm. br., with very 

 short linear cystoliths only seen on young shoots ; internodes very 

 variable in length, 1-4 cm. 1. Leaves 1*8-1 cm. br., with the two 

 lateral nerves produced to about three-fourths of their length; 

 petioles -3-1 cm. 1. Cymes solitary from axils of upper leaves ; 

 peduncles 3-4 cm. 1. Female floiuers sessile or subsessile. Acliene 

 1 mm. 1., broadly ovate, muriculate ; median segment of perianth 

 1*2 mm. 1., with tuberculate dorsal appendage; lateral segment 

 two-thirds as long as median. 



Hah. — In crevices of rocks ; Peckham Woods, Upper Clarendon, 

 2500 ft., Harris ! 10,946. 



This species is near P. crassifolia Bl. and P. reticulata Wedd., 

 but is easily distinguished from both by the form of the leaves. 



Pilea Elizabethae. Sujfrutex dioica (mascula tantum visa), 

 glabra. Folia ovata acuminata basi obtusa vel rotundata crenato- 

 serrata. StipidcB elliptic^ deciduae. Cymce dense multiflorae 

 paniculatae. Perianthii masculi appendices patentes. Types in 

 N. York Bot. Gard. and in Herb. Jam. 



Leaves 1 dm. 1. or less, 3-6 cm. br., nerves produced nearly to 

 the apex, with numerous dark sunken glands on lower face follow- 

 ing the course of the veins ; margin less coarsely serrate than in 

 P. grandifolia ; cystoliths on upper surface very unequal, fusiform 

 or punctiform, beneath subequal, linear, smaller and more frequent. 

 Stijndes 1 cm. 1. Cymes (including peduncle) shorter than the 

 leaves, 2-5-6 cm. 1. Male perianth globose, 1-2 mm. 1., with 

 patent thick appendages, -2 mm. 1. 



Hab.— mils near Bullstrode, March, Mrs. E. G. Britton, 2876 ! 



This species resembles P. grandifolia L., but is smaller with 

 ovate leaves, smaller deciduous stipules, and differs also in the 

 character of the inflorescence and in the male flower. 



The specific name is given in honour of the collector, Mrs. 

 Elizabeth G. Britton, the well-known American bryologist. 



This species is very near P. grandifolia BL, but the male 

 flowers differ, and the leaves are smaller and ovate. 



Pilea appendicilata. Sujfrutex monoica, caule simplici, 

 erecto, glabro. Folia ejusdem paris magis minusve inaequaha, 

 petiolata, ovata, acuminata, cordata, crenato-serrata dentibus 

 magnis, trinervia, supra glabra, subtus pilosa praecipue in nervis,
