SCHOMBURGK's GUIANA PLANTS. 119 



lyci interior! subaequilonga. Calyx interior late carnpanula- 

 tus, semi-5-fidus, laciniis ovatis, extus tonientoso-pubescens, 

 intus fere glaber. Corolla ampla, glabra. Tubus stami- 

 neus in toto fere longitudine antlierifer. Cocci membranacei, 

 dorso dehiscentes, laves, monospermi. — Moist savannahs, 

 British Guiana; Schomburgk, n. 68; Ceara; Gardner, n. 1458 ; 

 Bahia; Salzmann. This is probably the plant described by 

 A. de St Hilaire, as P. sessilijlora, but it cannot be the spe- 

 cies to which that name was originally given by Kunth, as 

 he expressly describes the ovary and cocci as hispid, besides 

 that the form of the leaves is not the same. 



635. P. cancellata, Cav DC. Prodr. v. i. p. 444. — Savan- 

 nahs, British Guiana; Schomhurgk, n. 273. Bahia; Gardner,

 cis exterioris foliolis circa 10 subulatis, interiore paullo lon- 

 giore laciniis ovatis, corolla ampla glabra, coccis reticulatis 

 inermibus. — Folia rigidula, 2 — 3-pollicaria, distantia, utrin- 

 que uti caulis inflorescentia et calyces pilis crebris stellatis 

 scabro-hispida. Flores in apices ramulorum 3 — 5, subcapi- 

 tati. Pedicelli crassi, calyce breviores. CalyK 4 lin. longus. 

 Petala sesquipoUicaria. Tubus stamineus in toto fere longi- 

 tudine antherifer, corolla paullo brevior ; stigmata 10; geni- 

 talia tamen in flore unico manco vix rite examinavi. Cocci 

 5, nigricantes, rete elevato rugosi, dorso leviter carinati, 

 monospermi, bivalvatim dehiscentes. — Swamps, Pirara ; 

 Schomburgk, n. 731. 



Gardner's n. 1244, from Alagoas, and n. 1457, 1460, and 

 1461, all from Ceara, are likewise species of Pavonia ; 

 n. 932, from Pernambuco is Lopimia malacopfiylla, Mart. 



637. Urena Americana, Linn. Jil. Suppl. p. 308. — I have 

 no doubt that most, if not. all the South American Urence 

 belong to this species ; but it appears to me to be distinct 

 from U. lobata, to which A. de St Hilaire refers it. — British 

 Guiana; Schomburgk, n. 1007; French Guiana; Herb. Par. 

 n. 126; Alagoas, Gardner, n. 1242.
