70 SOCIETY ISLANDS [Orchidea. 



aceis longe petiolatis grosse serratis triplinerviis piloso-hispidis subtus pallidioribus, spicis 

 axillaribus folia excedentibus glomerato-interruptis. 



This is nearly allied to Urtica cylindracea of North America, in the shape of its leaves and general 

 appearance of the flowers on the spikes ; but the former are constantly alternate, and the whole plant is 

 more hispid. 



1. Procris sessilis ; herbacea, erecta, foliis oblongo-lanceolatis acutis falcatis penninerviis 

 grosse serratis supra pragcipue pilis fusiformibus adnatis asperis basi obliquis subauriculatis 

 subsessilibus junioribus subtus hirsutis, stipulis oblongis membranaceis, capitulis masculis 

 sessilibus fcemineis pedunculatis involucratis. — Elatostema sessile. Forst. Gen. p. 106. — 

 Dorstenia pubescens. " Forst. Prodr. n. 59." — Procris australis. Spr. 



2. Procris integrifolia ; herbacea, erecta, foliis oblongo-lanceolatis acuminatis subfalcatis 

 obscure penninerviis integerrimis supra pilis fusiformibus adnatis asperis basi obliquis breve 

 petiolatis, stipulis lanceolatis, capitulis sessilibus. Don, Prodr. Fl. Nepal, p. 61. 



Our specimens of these two species of Procris are not in a sufficiently perfect state to allow us to jii'lge 

 how far one or other of them may belong to the Genera Elatostema and Sciophila, as denned by GaudicLaud 

 in the Botany of Freycinet's Voyage. The present species we possess from the Mauritius and Prince of 

 Wales Island, and it appears identical with the P. integrifolia of Mr. Don.

 1. Piper latifolium; fruticosum, foliis latissime cordato-subrotundatis 11- 5-nervhs 

 obtusis membranaceis petiolisque glabris, spicis axillaribus aggregatis. — " Forst. Prodr. 

 n. 22." 



1. Peperomia rhomboidea; herbacea, foliis rhombeo-rotundatis acutiusculis cornosis inte- 

 gerrimis breve petiolatis siccitate pellucidis 5-9-jierviis, spicis solitariis (?) filiforiiibus erectis 

 folio longioribus. 



Of this plant, the leaves are from an inch and a half to two inches or more in length, and about two- 

 thirds the length of the spikes, on petioles that are scarcely two lines long.
