 juniorum compresso-angulatis et ferrugineo- vel aureo-ferrugineo-tomentosis; rami primarii 

 infimi oppositi racemos abbreviatos in umbellam congestos gerentes ad umbellas usque 

 <-pollicares vel breviores, superiores in axillis bractearum oppositarum geminati racemos 

 abbreviatos gerentes. Bracteae omnes tomentosae, inferiores anguste oblongae superiores 

 ovatae. Pedicelli tomentosi versus medium bibracteolati (cum pedunculo Adr. Juss.) 

 usque 4 Yj-lineares. Sepala ovata, acuta, appressa, ferrugineo-tomentosa, 4 biglandulosa, 

 glandulis oblongis glabriusculis. Petala calyce longiora, unguiculata, unguiculo supra rubro 

 et lamina media carinata crassiusculo, lamina oblongo-ovata, obtusa, subintegra versus 

 basim margine leviter crispula, unius petali lacerato-ciliata. Filamenta glabra, basi 

 coalita, sepalis opposita et parum longiora. Germen ferrugineo -birsutum, tricoccum. 

 Styli tres erecti, glabri, breviusculi. Stigmata lateralia. Fructum et embryonem non 

 vidi, quapropter forsan potius Grisebachii sectioni 2. embryone endocarpii processum 

 amplectenti adscribenda est. Foliorum forma et pilositate denticulisque necnon ramis 

 compresso-angulatis insignis. Forsan paullo minores quam in H. chrysophyllae Kth., quae 

 praterea differt ramis teretibus, paniculis foliosis. An recte generi Heteropteridi annu- 

 merata? An potius Banisteria?

7. H. canaminensis (Rusby) Niedenzu. — Banisteria canaminensis Rusby in Mem. 

 New York Bot. Gard. VII. (^ 927) 275 (Heteropterys H.B.K.). — "Tomentellate throughout, 

 the stems somewhat scabrous, reddish, lightly sulcate. Leaves opposite, only the upper 

 seen, the petioles 5 mm long, stout, bearing 2 small black glands at the summit, the 

 blades 5 cm long and half as wide, oval with blunt or rounded base and lightly mucronate 

 summit, entire, thick, subglabrous above, softly tomentellate beneath, where the venation 

 is strongly prominent, the secondaries 4 on each side, strongly falcately ascending, 

 connected by a loose and prominent reticulation. Panicles terminal, large, lax, fer- 

 ruginous, the flowers crowded at the ends of the branchlets, the bracts small, thick, 

 densely ferruginous. Calyx 2 mm broad, \ O-glandular, 2 of the glands smaller, the 

 sepals thick, erect, equalling the fdaments, oval with rounded summit, lightly denti- 

 culate. Petals 3 — 4 mm long, shortly and stoutly unguiculate, yellow, broadly oval, 

 nearly plane, lightly denticulate. Stamens 10, all with anthers, half the length of the 

 petals, subequal, lightly connate at the base, the anthers lightly recurved, the connective 

 black, dorsally thickened, the thecae white. Ovary pilose, the styles about equalling 

 the stamens, very stout, erect, truncate. A single small fruit seen is apparently 

 immature. The body is not appendaged, and is pilose, the wing 2 cm long, 5 mm 

 broad, lightly ascending, the lower half of the inner margin shallowly excavated.
