Dr. Hamilton on a Plant allied to the Genus Piper. 11 



good deal both in general appearance and in the characters of 

 its fructification, from any of the species yet mentioned. In 

 the catalogue of dried specimens which I have given to the 

 India House, this plant has been called CuypHiEA ehecta, 

 on account of the sexual organs being concealed in a singular 

 manner by the filament, which resembles a berry. I shall 

 here give a description. 



Frutices erecti. Rami oppositi, glabri, intemodiis ad ba- 

 sin incrassatis compressis. Folia opposita, oblonga, ultra me- 

 dium latiora, acuminata, mucronata, serrata, venosa, undula- 

 ta, glabra. Petiolus brevissimus, annulo denticulato ramu- 

 lum cingente amplexicaulis. Stipula? alioquin nullae. 



Pedunculus communis terminalis, folio multo brevior, spi- 

 cas gerens quatuor brachiatim oppositas, ultra spicas mucro- 

 natus. Bracteo? ad singulas spicas minutae, ovatas, persisten- 

 tes, spicae (vel si velis amenta vel spadices) erectae, floribus 

 oppositis quadrifariam imbricatis quadrisulcae, glabrae, unciam 

 longae, mucronatae. Flores albi, parvi, singuli denticulo spi- 

 cae insidentes. 



Calyx squama minuta, acuta, denticulum spicas bracteans. 

 Corolla nulla. Filamentum unilaterale, ovatum, carnosum, 

 extra convexum, intus sinu excavatum. Anthera? dua3 unilo- 

 culars, marginibus filamenti infra apicem inserts. Germen 

 trigonum, filamentum inter et rachim intra filamenti sinum 

 nidulans, denticulo spicae insidens. Stylus brevis, crassus. 

 Stigma acutum integrum. 



Bacca ovata, carnosa, albida magnitudine pisi minoris, api-
