1. Anisolobus Perottetii, a. DC. Prodr. viii. p. 395; Miill. 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, 1-1 J in. broad, on petioles 3 lines long ; 

 calyx 3| lines long ; corolla 2 in. long. 



The description of the plant from Maranhao under this name, by Miiller, differs from 

 that of DeCandolle in several respects, indicating a specific difference, its leaves being 

 5:^9^ in. long, lf-1^ in. broad, on petioles 4^-5 J lines long ; while his variety obtusa, 

 from Matto Grosso, appears still more distinct. 



2. Anisolobus Salzmanni, A. DC. I. c. p. 395; Miill. I. 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, 4|-7 in. long, 2-3 in. broad, on petioles 3f-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, Sf- 5^ lines long, unequal, much imbricated, subciliate, with a few internal basal 

 scales ; tube of coroUa 1 in. long, enlarging at the base and upwards ; segments about the 

 same length ; disk entire (but doubtfully according to DeCandoUe), 2-3 lines long, con- 

 cealing the ovaries ; Miiller 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 constrietis, integris, rigidule chartaceis, supra rufiile 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 

 braeteolatis, ultimis congestis ; sepalis oblongo-ovatis, valde imbricatis,extus puberuliSj intus pruinosis, 

 squamulis paucis basalibus munitis; coroUse tubo cylindrico, pauUo sub medium constricto, 

 superne sublatiore, extus pruinoso ; segmentis oblique oblongis, dextrorsum convolutis ; disco urceo- 

 lato ad medium 5-sulcato, margine denticulato, ovaria 3 pilosula paullo superante ; staminibus ad 

 contractipnem tubi insertis, inclusis. In Guiana : v. s. in herb. Mus. Brit. (Schomburgk 212) . 



Axils 3 J 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, 2^ 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 immerses subpuberulis, subtus hepatice 

 flavescentibuSj opacis, costa nervis venisque transversis reticulatis rubidulis valde prominentibus ; pe- 

 tiolis semiteretibus, sulcatis, limbo 15plo brevioribus: racemo terminal!, alternatim 5-6-floro; 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 5^ in. long, IJ in. broad, on
