SCHOMBURGK's GUIANA PLANTS. Ill 



wer, n. 1267, has the leaves as figured by Aublet, in his Iron- 

 cana Guiatiensis, from three to five inches long, with the fruit 

 three or four lines in diameter. Vahl reduces the Iroucana 

 to his C. ramiflora^ from St Croix, but describes the leaves 

 as two inches long, and the fruit as of the size of a grain of 

 pepper. The two are therefore perhaps distinct. Gardner's 

 n. 2312, which I have in fruit only, is probably an undescribed 

 species of this section. Blanchet's n.3119,from VilladoBarra, 

 is very near Aublei's Iroucana, but has much larger stipules, 

 smaller flowers, and the anthers very short and apiculated. 



613. C. (Pitumba) macrop/iylla, Vahl— DC. Prodr. v. ii. 

 p, 50. — French Guiana, Herb. Par. n. 95 and 96. — C. mollis, 

 of Humb. and Kunth, is closel}' allied to this species, and 

 scarcely differs but in the hairiness of the leaves. 



614. C. (Pitumba) stipularis, Vent. — DC. Prodr. v. ii. p. 50. 

 — Rocky situations, Pirara ; Schomburgk, n. 704. I have it 

 also from the West Indies, and from Brazil. Gardne?*s n. 

 1524, and 1525, from Ceara, appear to be both of them the C. 

 grandiflora, St Hil. — C. hypoleucOy Mart, is closely allied to 

 the above two species. 



615. C. (Pitumba) pe^r^a (sp. n.); foliis ovali-ellipticisacu- 

 minatis mucronato-serrulatis basi rotundatis utrinque ramu- 

 lisque rufo-pubescentibus punctatis, floribus parvis, umbellis 

 axillaribus sessilibus, calyce tomentoso 5-fido laciniis ovato- 

 orbiculatis, staminibus fertilibus 10 calyce paullo brevioribus, 

 stylo indiviso A descriptione C. Mrsiitee differt umbellis ax- 

 illaribus, laciniarum calycis forma, etc.; a C. rufescente, St 

 Hil. foliis majoribus supra pubescentibus aliisque notis. 

 Frutex est. Folia 3 — 4-pollicaria, utrinque prassertim sub- 

 tus molliter pubesceniia, crebre punctata. FJores multo 

 minores quam in C. stipidari, majores quam in C. parvijlora. 

 Filamenta sterilia angusta, hirta ; fertiiia glabra. Anlherae 

 breves, connectivo apiculatoe, et pilis paucis brevibus ciliatse. 

 Ovarium pubescens, stylo brevi, stigmate capitato. — Stony 

 savannahs, Pirara, Schomburgk, n, 718. 



Of the section Pitumba, I have also examined Gardner's 

 n. 348, from the Organ Mountains, which may be C. pauci-
