84 ON SOUTH-AMERICAN APOCYNACEZ. 
lanceolate, 14 line long, connate at the base, cinereo-pilose ; tube of corolla cylindrical, 
angular, pilose outside, glabrous within, except a narrow pilose ring in the contracted 
mouth, below which it is somewhat swollen, 4 lines long; segments oblong, obtuse, 
3 lines long, slightly dextrorsely convolute in sestivation; 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 placente aggluti- 
nated together, nearly reaching the opposite side of the cell, each bearing on its outer 
face 4 or 5 seeds, their summits overlapping 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 half-imbedded; embryo in thin albumen, with 2 cordate cotyledons, and 
a radicle half their length, pointing to the apex of the follicle. 
Dr. Freire Allemáo (loc. cit.) correctly repudiates the reference of this plant by Riedel 
to Vallesia, on account of its extra-axillary inflorescence, and especially the character 
of its fruit and seeds. 
The analysis of its fruit and seeds (from Allemáo), is given in Plate XII. a.

This is à species very different from the preceding, though united with it by Dr. 
Allemáo. 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 3-flowered short 
raceme (not a divided panicle of 8 flowers), calyx and corolla glabrous outside (not 
pubescent), in its follicles very acute and reflexed at the apex, in its thicker, glabrous, 
yellow pericarp replete with a lactescent juice, containing 4 (not 8 or 10) seeds. Dr. 
Müller (Fl. Bras. fase. xxvi. p. 90) could only reconcile these differences 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 11-2 lines long; the 
pedunele of the infra-axillary inflorescence is 3 lines long, and supports generally 3, 
sometimes 2, subalternate bracteolated pedicels 13-2 lines long; the acuminate glabrous 
sepals are 13 line long; corolla yellowish white, glabrous outside, everywhere puberulous 
within, has a cylindrical tube 6 lines long, with oblong segments 44 lines long, a little 
convoluted in sstivation; 2 oblong follicles, spreading, rounded at the base, terminated 
by a long reflexed acute point, 23 in. long, 14 in. broad, each containing 4 separate 
seeds, as distinetly stated by Velloz; these are oval, compressed, 8 lines long, 6 lines 
broad, half-immersed in a white succulent funicle.
