Müller states that the Peschiera latifolia (Spruce 236), from Santarem, is identical 
with Willdenow's plant. Spruce's plant and Müller's drawing are now placed before me 
side by side; and I can pronounce them to be distinct, not only in a specific point of view, 
but that they belong to two different genera. Müller's copious description of Taberne- 
montana flavicans is therefore of no value, as the characters are mainly derived from 
Spruce’s plant. We have no trustworthy evidence in regard to the species in question, 
except the short character of this plant as quoted by De Candolle; to this we may add 
Müller's plate 25, above mentioned, which appears to have been made from Willdenow's 
typical specimen, which coincides sufficiently well with the original description. From 
these two sources the following diagnosis is drawn up. Müller gives no analysis of the 
flower; it is therefore probable that he never saw the specimen, and that he obtained his 
drawing from some other source. 
It has very slender, dichotomous, erect branchlets, with axils 1-12 in. apart; the 
opposite leaves, of equal length, are very lanceolate, very acute at the base, with a 
gradually narrowing blunted acumen, 2-23 in. long, 4-5 lines broad, on slender petioles 
24-3 lines long; the lateral raceme has a peduncle bare at the base for 6 lines, bearing 
3-4: alternate flowers above, on bracteolated pedicels 3-4 lines long; sepals acute; tube 
of corolla 1 in. long, narrowly cylindrical, 14 line thick, swelling below the mouth to a 
breadth of 2 lines; segments oblong, when expanded 1 in. long, 5 lines broad; stamens 
included and inserted in the constriction, at 3 the length of the tube. These characters 
are obviously those of Anartia; and the species closely approaches 4. recurva. 
6. ANARTIA FLAVESCENS, nob.: Tabernemontana flavescens, R. & Sch. Syst. iv. 797; A. DC. I. c. p. 375. 
In Brasilia: non vidi. 
A species evidently near the preceding, with broader, more shortly acuminate, oblong 
leaves 2 in. long; an axillary peduncle, bracteolated, 2 lines long, bearing subumbellate 
flowers on filiform pedicels 1 in. long; the flowers less than 6 lines long. 
7. Anartia Bocorensis, nob.: Echites Bogotensis, H. B. K. iii. 215, tab. 243; A. DC. 4. c. p. 474: 
Amblyanthera Boyotensis, Müll. Linn. xxx. 452. In Ecuador, Santa Fé de Bogota: non vidi. 
A species certainly not belonging to Amblyanthera. It is a scandent plant, with 
straightish, terete, striated, canescently subpubescent branches, with axils 11-2 in. apart ; 
leaves oblong, rounded or obsoletely cordate at the base, acuminate, submembrana- 
ceous, with entire or subrevolute margins, green and glabrous above, with 2 bifid fleshy, 
glabrous glands superposed at the base of the midrib, reticulately veined, beneath 
densely glauco-farinaceous and subpubescent, 2) in. long, 11-14 lines broad, on chan- 
nelled puberulent petioles 3 lines long; 2 opposite racemes, 24 in. long, including a 
short peduncle 2-3fid at the base, each branch bearing several alternate flowers the size 
of those of Vinca minor, on pedicels 4-5 lines long, supported by an acute bract 4 line 
long; sepals acute, oblong, imbricated, glabrous, with as many alternate inner trifid
