118 SCHOMBURGK's GUIANA PLANTS. 



obtusiusculis remote serratis basi rotundatis supra tubercu- 

 loso-pubescentibus subtus molliter tomentosis. — Evidently 

 very near to P, tomentosa of Humboldt and Kunth, with 

 whose description it agrees in every respect, except that the 

 leaves are more sessile, longer, and much rounded, or even 

 nearly cordate at the base. — Banks of the Rupunoony; Schotn- 

 burgk, n. 127, in some sets. 



Malvace^. 



632. Pavonia typhalea, Cav. — DC. Prodr. v. i. p. 443. — 

 On the Essequibo; Schomburgk, n. 137, and in several West 

 Indian and Brazilian collections. 



Gardner's n. 324, from the Organ Mountains, is a new 

 species allied to P. typhalea, but remarkable for the solitai-y 

 aristffi on each coccus ; n. 322, from the same locality, is 

 P. sepium, St Hil., or P.Jlava, Spreng., the number of leaf- 

 lets of the outer calyx varying from five to eight on the same 

 specimens, although it be most frequently even on Martius's 

 specimens five or six. 



633. P. speciosa, Humh. et Kunth. — DC. Prodr. v. i. p. 

 443. — Arid savannahs, Pirara, and on the Rupunoony, 

 Scliomburgk, n. 253. 



Gardner's n. 2398, from Ceara, allied to this species, is, as 

 far as I can ascertain from my imperfect specimens, the 

 P. pellita, Humb. et Kunth. 



634. P. bracteosa (sp. n.) ; fruticosa, molliter incano-to- 

 mentosa, foliis ovato-orbiculatis obtusis v. vix acuminatis basi 

 profunde cordatis, floxalibus sessilibus basi subcoloratis, flori- 

 bus sessilibus, involucri folioUs linearibus apice uncinate re- 

 flexis, coccis 5 glabris. — Frutex 6— 8-pedalis. Folia breviter 

 petiolata, 1 — 2 poll, longa, crenata, reticulato-rugosa ; utrin- 

 que pube molli prsesertim subtus canescenti-tomentosa, 

 minute pellucido-punctata. Stipulae parvae, setaceae. Flores 

 in apicibus ramulorum congestae, foliis floralibus caulinis sub- 

 conformibus at minoribus circumdatse. Foliola calycis exte- 

 rioris circiter 11, lineari-subulata hispida, apice lamina 

 foliacea latiore reflexa supra basin afiBxa appendiculata, ca-
