SANDWICH ISLANDS. 
[Piperacea. 
1. Pilea peploides; foliis longe petiolatis rhomboideo-orbiculatis integerrimis glabris, 
floribus axillai-ibus glomeraio-racemosis. — Dubreulia peploides. Gaud, in Freyc. Voy. p. 495. 
This ^emis, by its sessile, multifid stigma, approaches most to Procris, but its habit is that of Parietaria. 
The character of Dubreulia, as given by Gauctichaud, is nearly as follows : — Flores sessiles ; masculi et foeminei 
in eadem panicula, bracteati. Masc. perianthium 4-partitum. Stamina 4. Pistilli rudimentum clavatum. 
Fcem. perianthium 3-lobum, lohis valde insequalibus, exteriore maximo incrassato cucuUato. Stamina 3, sterilia, 
squamiformia, incurva. Stigma sessile mnltipartitum. — Gaudichaud does not seem to be aware of its identity 
with Pilea of Mr. Lindley. Urtica serpyllacea, microphylla, callitrichoides, and several others, belong to it. 
1. Procris glabra; foliis alternis ovatis vix acuminatis crenato-serratis glabris laevibus, 
cymis divaricatis pedunculatis. 
Procris, with which we consider Elatostemma identical, as also Sciopliila, PelUonia, and Langeveldia 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, aclienio ovato-elliptico. 
A very handsome species, belonging to the section Pi'ocris of Gaudichaud ; but we have, along udth 
Sprengel, retained that name for what Gaudichaud calls Elatostemma. 
2. Boehmeria melastomopfolia ; foliis alternis oblongis acuminatis basi acutis trinerviis 
glabriusculis subtus pallidioribus, perianthio demum carnoso, achenio depresso-conico. — 
Neraudia melastommfolia. 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 siu-rounding the ripe fruit. We do not think it necessary to sepai’ate 
them. 
Ord. XLIV. PIPERACE^. Rich. 
1. Piper methysticum ; fruticosum, foliis cordato-oblongis acuminatis multinerviis glabris, 
spicis solitariis axillaribus brevissimis patentissimis. Spr . — “ Forst. Prodr. n. 21.” Spreng. 
Syst. Veget. v. \. p. 113. 
1. Peperomia pallida; caule erecto glabro, foliis alternis oblongo-ellipticis glabris 3- 
nerviis, spicis axillaribus solitariis filiformibus, baccis distinctis. — Piper pallidum. “ Forst. 
Prodr. n. 24.” Spreng. Syst. Veget. v. 1. p. 116. 
2. Peperomia leptostachya ; caide erecto tomentoso, foliis quaternis ovato-ellipticis acuti- 
usculis trinerviis utrinque 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. \eget. v. 1. p. 119. 
4. Peperomia ? menibranacea ; caule erecto glabro, foliis subquaternis ovatis acuminatis 
trinerviis glabris membranaceis subtus pallidioribus, spicis axillaribus terminalibusque 
gracilibus.
