sublucide opacis, nervis arcuatis subimmersis, subtus pallidioribus, opacis, sub lente 
minutissime punctulatis, nervis venisque transversis vix conspicuis ; petiolo sulcato, 
striato-ruguloso, limbo 16-plo breviore: paniculis in axillis solitariis, terminalibus 
subfascieulatis, folio brevioribus, alternatim vel dichotome ramosis, ramis ramulisque 
angulato-striatis, angulis seepe rugulosis, fuscis, vix divaricatis; bracteolis alternis

ribus, obovatis, imo angustatis, submembranaceis, integris vel sinuato-crenatis, 
luteis; disco breviter tubuloso, margine sublobato, crenulato; filamentis disco 3-plo 
longioribus, apice reflexis; antheris majusculis, obscure luteis; stylo brevi, crassius- 
culo; stigmatibus 3, latiusculis, acutis, valde reflexis; ovarii loculis 6-ovulatis. In 
Brasilia: v. s. in herb. meo et aliorum, prov. Piauhy (Gardner, 2789); v.s. in herb. 
Mus. Brit. et Hook., prov. Minas Geraés, distr. adamantina (Gardner, 4459). 
A low shrub, from the upland campos of the diamond district, where it attains the 
height of 3 or 4 feet, sometimes 1 foot only; it is very different in appearance from any 
of the preceding species, especially in its habit, resembling some species of Raddia, but 
differing from them in floral structure. The axils, mostly alternate, are $ in. apart ; the 
leaves are 2-2$ in. long, 7-11 lines broad, on a petiole 14-2 lines long; the panicle is 
3-1 in. long, the peduncle 5 lines, its branches each 3 lines long, and somewhat erect ; 
the bracteoles small, membranaceous, with ciliated margins; the flower expanded is 14 
line in diameter; the petals are reflected at their apex, somewhat unguiculated or nar- 
rower at their base. 
9. TONTELEA BRACHYPODA, nob.: ramulis teretibus, striatis, rubro- vel flavide brunneis : 
foliis sepius alternis, longe lanceolatis, imo acutis et in petiolo decurrentibus, 
sursum gradatim attenuatis, acumine sensim obtusulo vel acutato, glaberrimis, 
coriaceis, planissimis, marginibus cartilagineis vix revolutis, integris aut obsolete 
subsinuato-undulatis, supra viridibus, opacis, nervis venisque transversis subim- 
mersis, subtus pallidioribus, opacis, nervis parallelim longe adscendentibus, crassi- 
usculis, venis corrugulatis paulo prominulis, sub lente minute granuloso-punctulatis ; 
petiolo brevissimo, fusco, crassiusculo, supra plano, subtus corrugulato, limbo 20-plo 
breviore: paniculis axillaribus, folio 5-plo brevioribus, crebre alternatim multidivisis, 
ramulis brevissimis, unibracteolatis, glabris, fuscis, compressis, floribus in ramulis 
ultimis hine subaggregatis, parvis, pedicellatis, numerosis ; sepalis semiorbicularibus, 
fuscis, crassiusculis, eroso-ciliatis, ; petalis oblongis, pallidis, crassiusculis, 4-plo longi- 
oribus, eroso-denticulatis; disco breviter tubulari, crebre crenulato; stylo brevi; 
stigmatibus 3, longiusculis, acutis, reflexis, intus papillosis. In Brasilia: v. s. in 
herb. Hook., prov. Goyaz, Rio das Velhas (Burchell, 5798). 
This species somewhat approaches 7. longifolia: the axils of its branches are 17-13 in. 
apart ; the leaves are 44-5 in. long, 1-13 in. broad, on a petiole 25 lines long; the panicle 
is Lin. long, with very numerous crowded ramifications ; the pedicel is extremely short ; 
the sepals and petals are thick, with eroso-ciliated margins; the disk is a short tube of 
thin texture, with a finely crenulated margin; the stamens, litile exserted, have reniform 
anthers of a dark orange-colour ; the flower expanded is 2 lines in diameter.
