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 stigina, 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. 

 F<em. perianthium 3-lobum, lobis valde inajqualibus, 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 seipyllacea, ■microphylla, callitrichoides, and several others, belong- to it. 



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

 cymis divaricatis pedunculatis. 



Procris, with which we consider Elatostemma identical, as also Sciophila, Pellionia, and Langeveldia of 

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

 on one side. 



1. Boebmeria 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 Elatostemma. 



2. Boebmeria mdastomcefolia ; foliis alternis oblongis acuminatis basi acutis trinerviis 

 glabriusculis subtus pallidioribus, periantbio demum carnoso, achenio depresso-conico. — 

 Neraudia melastoma^folia. Gaud, in Freyc. J oy. 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.

 usculis trinerviis uti'inque pubescentibus, spicis axillaribus terminalibusque pedunculatis 

 gracilibus folio longioribus. 



3. Peperomia verticillata ; caule erecto, foliis subquaternis obovatis obtusis subtrinerviis 

 pubescentibus subtus convexis, spicis axillaribus terminalibusque verticillatis. Spr. — Piper 

 verticillatum. Linn. — Spreng. Syst. Veget. v. 1. p. 119.

 gracilibus.
