paulo divaricatis, imo unibracteolatis, glabris, striolatis, ultimis florem unicum pedi- 
eellatum gerentibus, ramulis nonnullis deciduis; bracteolis minutis, acutis: floribus 
parvis, fuscis; sepalis rotundatis, glabris, marginibus submembranaceis; petalis 
duplo longioribus, unguiculato-obovatis, luteis, membranaceis, margine papilloso- 
ciliatis, extus crebre papillosis: ceeteris ut in diagnosi generica. In Brasilia septen- 
trionali: v. s. in herb. meo et aliorum, prov. Pará, ad Obidos (Spruce 514). 
The axils of the slender branchlets are about 2 inches apart. The leaves are 51-61 in. 
long, 11-2 in. broad (the acumen being 6 lines long, 1 line broad), on a petiole 2 lines 
long. The slender panicles are 23 in. long; the axillary gemmule is 1 line long; the two 
peduncles rising out of it are 9 lines long, the primary branches 8 lines long; the rest 
diminish upwards to 2 lines in length; these are 1-bracteolated at their base, and often 
pluribracteolated in the middle where the branchlets have fallen off, the pedicels being 
3-4 lines long and very slender; the flowers are extremely small, the erect petals being 
only 3 line long. | 
2. AMPHIZOMA TENUICULA, nob.: ramulis tenuibus, subangulatis, striatis, tuberculis 
nigris concavis verruculosis: foliis oppositis, oblongo-ellipticis, imo acutiusculis, 
apice in acumen obtusulum sensim attenuatis, marginibus tenuiter cartilagineis 
subrevolutis, integris, supra pallide viridibus, subnitentibus, nervis tenuissimis cum 
pluribus intermediis venisque reticulatis vix prominulis, subtus paulo pallidioribus, 
vix opacis, venis reticulatis subimmersis, sub lente minute et creberrime granulosis ; 
petiolo tenui, flavido, canaliculato, corrugulato, limbo 10-plo breviore: pedunculis 
axillaribus, brevissime pedunculatis, alternatim longiuscule ramosis, ramis alternatim 
breviter ramulosis, et imo unibracteolatis, paulo divaricatis, angulato-compressis, 
griseo-papillosis, ultimis flores 2 breviter pedicellatos gerentibus; floribus parvis; 
sepalis rotundatis, crassis, extus griseo-farinosis; petalis duplo longioribus, oblongis, 
carnosulis, luteis, utrinque papilloso-tomentellis, marginibus membranaceis erosule 
denticulatis: ceteris ut in diagnosi generica. In Brasilia centrali: v. s. in herd. 
Hook. sine loco (Sello). 
The axils of its slender branches are 2 inches apart: the leaves are 3-33 in. long, 
11-12 in. broad, on a petiole 4 lines long: the panicle is 13 in. long, the peduncle 1 line 
long, the primary branches 4-6 lines long, the secondary 4-5 lines long, the rest gra- 
dually diminishing upwards, the last 1 line long, the pedicel half a line long; the petals 
are ¿line long; here the form and position of the stigmata are most distinctly seen, 
standing opposite to the stamens. 
9. AMPHIZOMA MARTIANA, nob.: ramulis teretibus, subgriseis, ruguloso-striatis, verru- 
culis nigris crebre asperatis, axillis compressis et dilatatis: foliis magnis, oppositis, 
oblongis, infra medium sensim angustioribus, imo obtusis, aut rotundiusculis, apice 
rotundatis et acumine brevi obtuso recurvo subito apiculatis, marginibus tenuiter 
cartilagineis revolutis, integris, remote undulato-sinuatis, coriaceis, supra subni- 
tentibus, nervis tenuissimis utrinque circa 10 valde divaricatis arcuatim nexis cum 
alis intermediis brevioribus valde reticulatis paulo prominulis, eosta fulvescente
