14 inch broad, on a petiole of 3 lines; the peduncles are from 4 
to 6 lines long ; the calyx urceolate, 1 lie long; the tube of the 
corolla 3 lines, its segments 2 lines long*. 
10. Brachistus dimorphus (n. sp.) ;—fruticosus, rainulis teretibus, 
glaberrimis ; foliis elongato-lanceolatis, apice acuminatissimis, 
basi oblique in petiolum attenuatis, adultis utrinque glabris, 
supra ad rachin scabrido-pilosis, margine subciliatis, junioribus 
sparse pilosis, geminis, difformibus, altero multo mimori, ro- 
tundato-ovato, sessili, basi inzequali, supra glabro, subtus pal- 
lide fulvescente ; floribus pentameris binis, extra-axillaribus, 
cernuis, petiolo brevioribus; calyce urceolato, fere integro, 
pubescente ; corolle tubo brevissimo, limbo 5-partito, expanso, 
lobis acutis ; filamentis subulatis, compressis, glabris ; antheris 
oblongis ; stylo exserto, subincurvo ; ; stigmate clavato, sub-2- 
lobo.— Nova Granada, v. s. in herb. Hook. (Los Tapios, Quin- 
diu, Goudot.) 
This species is very distinct, its larger leaves being so extremely 
different in form from the others ; i they are 35-33 inches long, 
} ich wide, on a petiole barely 3 inch in length: the smaller 
geminate leaf being 10 lines long and 7 lines broad ; the peduncle 
is scarcely 2 lines, and the corolla 2 lines in length ; the calyx 
is 1 line long and in diameter, submembranaceous, without ner- 
vures, and with five obsolete teeth on its almost entire margin ft. 
11. Brachistus? lanceefolius (n. sp.) ;—ramis ferrugineo-tomen- 
tosis, dichotomis, ramulis angulatis, divaricatim flexuosis, vix 
ligneis ; foliis alternis, lanceolatis, utrinque acuminatis, inte- 
gris, supra parce, subtus densius fulvo- puberulis, petiolo sub- 
brevi; floribus e dichotomiis solitariis, vel e turionibus fasci- 
culatis ; ; pedunculis 1-4, unifloris, pilosis, apice incrassato- 
incurvis ; calyce piloso brevi, urceolato, angulato, margine fere 
integro, ‘dentibus 5 minimis instructo; corolla rotata, sub- 
glabra, limbo 5-lobo, lobis acutis, triangularibus, reflexis, mar- 
gine floccosis ; staminibus inclusis, erectis, glabris ; sty lo apice 
incrassato, stigmate capitato-bilobo.—America equinoctialis, 
v. s.in herb. Hook. (Loxa, regno Quitensi, Seemann, p. 879.) — 
(Vita, Peruvie, McLean.) 
This is a plant very distinct from the others, with very dicho- 
tomously spreading branches, which have a more medullary and 
less ligneous substance : there is no indication of fruit in the spe-
