1. AwrsoLoBUs Perorreriu, A. DC. Prodr. viii. p. 395; Müll. Fl. Bras. xxvi. p. 115. In Guiana (Pe- 
rottet): non vidi. 
A species, with straight, verrucate branches, furnished on each side of the nodes with 
2 small stipules; leaves distichous, oblong, acute at the base, acuminate, furnished with 
many close nerves and reticulated veins, 3 in. long, 1-14 in. broad, on petioles 3 lines long; 
calyx 32 lines long; corolla 2 in. long. ; 
The description of the plant from Maranháo under this name, by Müller, differs from 
that of DeCandolle in several respects, indicating a specific difference, its leaves being 
51-93 in. long, 14-14 in. broad, on petioles 44-54 lines long; while his variety obtusa, 
from Matto Grosso, appears still more distinct. 
2. ANISOLOBUS SALZMANNI, A. DC. Z. c. p. 395; Müll. /. c. p. 113. In Brasilia, prov. Bahia : non vidi. 
A scandent plant, with glabrous branches, the branches pubescent at the summits ; 
leaves opposite (but not distichous), ovate or oblong-ovate, very obtuse at the base, 
somewhat blunt at the acuminate apex, coriaceous, glabrous, shining, fuscous-green 
above, pallid beneath, with darker nerves, 43—7 in. long, 2-3 in. broad, on petioles 34—4 
lines long; racemes terminal, densely flowered, on a short peduncle furnished with 
numerous roundly ovate bracts ; pedicels twice the length of the petioles ; sepals broadly 
oblong, 33-51 lines long, unequal, much imbricated, subciliate, with a few internal basal 
scales ; tube of corolla 1 in. long, enlarging at the base and upwards; segments about the 
same length; disk entire (but doubtfully according to DeCandolle), 2-3 lines long, con- 
cealing the ovaries; Müller states that it is partially cleft into 5 crenulate lobes. 
3. ANISOLOBUS DISTINCTUS, nob.: ramulis crassiusculis striolatis, axillis remotiusculis stipulaceis : foliis 
late ovatis aut oblongis, imo rotundatis, interdum circa petiolum brevissime acutatis, apice in acumen 
late lineare obtusum repente constrictis, integris, rigidule chartaceis, supra rufule viridibus, nervis 
nigris arcuatim nexis subimmersis, subtus flavide opacis, nervis fulvidis venisque transversis valde 
reticulatis vix prominulis ; petiolo fusco, semitereti, quam limbus 8plo breviore: racemis terminalibus 
geminatis, pedunculatis ; pedunculis nudis apice laxe 8-10-floris; pedicellis oppositis, imo breviter 
bracteolatis, ultimis congestis ; sepalis oblongo-ovatis, valde imbricatis, extus puberulis, intus pruinosis, 
squamulis paucis basalibus munitis; corolle tubo cylindrico, paullo sub medium Sege, 
superne sublatiore, extus pruinoso ; segmentis oblique oblongis, dextrorsum convolutis ; disco urceo- 
lato ad medium 5-sulcato, margine denticulato, ovaria 2 pilosula paullo superante ; staminibus ad 
contractionem tubi insertis, inclusis. In Guiana: v. s. in herb. Mus. Brit. (Schomburgk 212). 
Axils 31 in. apart; leaves 5-6 in. long, 3-3) in. broad, on rather stout petioles 8 lines 
long; panicles 3 in. long; bare peduncles 9 lines long; pedicels 4 lines long; sepals, very 
young, 21 lines long, roundish ; corolla, in bud, 1 in. long. 
4. ANIsoLOBUS OBLONGUS, nob.: ramulis teretibus, subtenuibus, glabris, ad nodos stipularibus : foliis 
elongato-oblongis, imo obtusis, superne sensim acutis, marginibus subundulatis, chartaceis, supra 
fusco-viridibus, pruinoso-opacis, in costa sulcatis, ad nervos immersos subpuberulis, subtas/ hepatice 
flavescentibus, opacis, costa nervis venisque transversis reticulatis rubidulis valde prominentibus d pe- 
tiolis semiteretibus, sulcatis, limbo 15plo brevioribus: racemo terminali, alternatim 5-6-flaro ; floribus 
pro genere speciosis, flavis. In Brasilia: v. s. in herb. Mus. Brit. Itagoahy (Bowie & Cunningham). 
The slender branch has axils about 1 in. apart; leaves 53 in. long, 13 in. broad, on
