lanceolate, 1^ line long, connate at tlie base, cinereo-pilose ; tube of corolla cylindrical, 

 angular, pilose outside, glabrous witbin, except a narrow pilose ring in tbe contracted 

 mouth, below wMch it is somewhat swollen, 4 lines long; segments oblong, obtuse, 

 3 lines long, slightly dextrorsely convolute in aestivation ; anthers free, ovate, cordate, 

 on short pubescent filaments; disk very pilose, concealing the ovaries; follicles spread- 

 ing, 2 in. long, 1 in. broad, with a pericarp 3 lines thick, 2 sutural placentae aggluti- 

 nated together, nearly reaching the opposite side of the cell, each bearing on its outer 

 face 4 or 5 seeds, their summits overkpping each other ; seeds ovoid, 7 lines long, 4 lines 

 broad, with a central hilum on one face, where they are attached to a fleshy funicle, in 

 which they are haK-imbedded ; embryo in thin albumen, with 2 cordate cotyledons, and 

 a radicle half their length, pointing to the apex of the follicle. 



Dr. Ereire AUemao {loc. cit.) correctly repudiates the reference of this plant by Riedel 

 to Vallesia, on account of its extra-axUlary inflorescence, and especially the character 

 of its fruit and seeds. 



The analysis of its fruit and seeds (from Allemao), is given in Plate XII. A.

This is a species very diflferent from the preceding, though united with it by Dr. 

 Allemao. It differs in being a much smaller tree, with glabrous (not tomentous) 

 branchlets, in its much narrower lanceolate (not elliptic) leaves retuse (not undulated) 

 on the margins, quite glabrous (not pubescent), in its simple 2- or 8-flowered short 

 raceme (not a divided panicle of 8 flowers), calyx and corolla glabroiis outside (not 

 pubescent), in its follicles very acute and reflexed at the apex, ia its thicker, glabrous, 

 yellow pericarp replete with a lactescent juice, containing 4 (not 8 or 10) seeds. Dr. 

 Miiller (Fl. Bras. fasc. xxvi. p. 90) could only reconcile these diff'erences by inferring that 

 Velloz's details are not to be depended upon as to accuracy ; but no one would agree in 

 this opinion who has seen the delicately executed original drawings of Velloz (some of 

 which I possess), which were so roughly copied by the Paris lithographer. In these 

 plates of the ' Flora Fluminensis,' we may rely on the general accuracy of the rough 

 outlines of the plates, as to form and dimensions. In Velloz's plant the very glabrous 

 lanceolate -^ leaves are 2-3 in. long, |-1 in. broad, on petioles 1^-2 lines long; the 

 peduncle of the infra-axillary inflorescence is 3 lines long, and supports generally 3, 

 sometimes 2, subalternate bracteolated pedicels 1^-2 lines long ; the acuminate glabrous 

 sepals are 1 J line long ; coroUa yellowish white, glabrous outside, everywhere puberulous 

 within, has a cylindrical tube 6 lines long, with oblong segments 4J lines long, a little 

 convoluted in aestivation; 2 oblong follicles, spreading, rounded at the base, terminated 

 by a long reflexed acute point, 2J in. long, 1| in. broad, each containing 4 separate 

 seeds, as distinctly stated by Velloz ; these are oval, compressed, 8 lines long, 6 lines 

 broad, half-immersed in a white succulent funicle.
