FLORA OF BRAZIL. 187 
Has. In Capociras, common about Rio. FI. July. 
112. Julocroton nigrescens. Mart. Herb. Fl. Bras. 847. 
Has. Common everywhere about Rio. Fi. July. 
113 et 114. These I believe to be new species of Croton; 
but I refrain from describing them because Dr. Klotzsch 
is at present engaged upon a Monograph of the Euphorbi- 
acee ; and a set of my plants being in his hands, those of 
this natural order will no doubt find a place in his forth- 
coming work. Till this book appears I shall only refer 
my Euphorbiacee to their genus or order; and at some 
future period a correct list of their names will be pub- 
lished. 
115. Dorstenia arifolia, Lam.—Hook. Exot. Flora, 1. t. 6. 
Hook. Bot. Mag. t. 3074. 
Has. In woods, common about Rio. FI. Aug. Sept. 
116. Dorstenia Contrayerva. Linn.—Spreng. Syst. 3. p. 771. 
Has. In woods, common about Rio. Fi. Aug. 
116 (2). Dorstenia hispida. Hook. Icon. Plant. sub t. 220. (in 
annot.) 
Has. Rare, on the banks of the Rio Comprido, near Rio de 
Janeiro, and not on the Organ Mountains as stated by 
Sir William Hooker. On my return to Rio in the end of 
the year 1840, I again found one or two specimens of it 
in a wood at Tijuca. 
117. Sponia micrantha. Decaisne, Herb. Tim. p. 170.—Cethis 
micrantha, Sw. 
AB. Common on the Corcovado. FI. July. 
118. Steffensia Gaudichaudiana. Kunth, in Linnea 13. p. 638. 
Has. In shady virgin forests, on the Corcovado. FI. Aug. 
Ámong my own specimens under this number, I find one 
of S. salicariefolia, (Kunth), which makes it probable that 
the two species were mixed up at the general distribu- 
tion, 
119. Schillera colubrina, Kunth in Linnea, vol. 13. p. 655.— 
iper colubrinum, Link. 
Has. In dense virgin forests, on the Corcovado. FI. Aug.
