96 SANDWICH ISLANDS. [Piperacece. 



1. Pilea peploides; foliis longe petiolatis rhomboideo-orbiculatis integerrimis glabris, 

 floribus axillaribus glomerato-racemosis. — Dubreulia peploides. Gaud, in Freyc. Voy.p. 495. 



This genus, by its sessile, multifid stigma, approaches most to Procris, but its habit is that of Parietaria. 

 The character of Dubreulia, as given by Gaudichaud, is nearly as follows : — Flores sessiles ; masculi et foeminei 

 in eadem panicula, bracteati. Masc. perianthium 4-partitum. Stamina 4. Pistilli rudimentum clavatum. 

 FffiM. perianthium 3-lobum, lobis valde insequalibus, exteriore maximo incrassato cucullato. Stamina 3, sterilia, 

 squamiformia, incurva. Stigma sessile multipartitum. — Gaudichaud does not seem to be aware of its identity 

 with Pilea of Mr. Lindley. Urtica serpyllacea, microphylla, callitriclwides, and several others, belong to it. 



1. Procris glabra; foliis alternis ovatis vix acuminatis crenato-serratis glabris lsevibus, 

 cymis divaricatis pedunculatis. 



Procris, with which we consider Elatosternma identical, as also Sciophila, Pellionia, and Langeveldiu of 

 Gaudichaud, differ from Boehmeria by the stigma, which, in the latter genus, is simple, elongated, and villous 

 on one side. 



1. Boehmeria albida ; dioica arborea, foliis alternis late ovatis acuminatis trinerviis 

 serratis supra minute rugosis et pubescentibus subtus albido-tomentosis, capitulis utriusque 

 sexus globosis axillaribus sessilibus, perianthio membranaceo, achenio ovato-elliptico. 



A very handsome species, belonging to the section Procris of Gaudichaud ; but we have, along with 

 Sprengel, retained that name for what Gaudichaud calls Elatosternma. 



2. Boehmeria melastomcefolia ; foliis alternis oblongis acuminatis basi acutis trinerviis 



glabriusculis subtus pallidioribus, perianthio demum carnoso, achenio depresso-conico. 



Neraudia melastomaefolia. Gaud, in Freyc. Voy. p. 500. t. 117. 



Neraudia of Gaudichaud is principally distinguished from Boehmeria by the shape of the achenium 

 and the consistence of the perianth surrounding the ripe fruit. We do not think it necessary to separate 

 them.
