NOTES ON HUMIRIACES. lu 
inch long, grows chiefly along the sea-coast, and several intermediate 
forms occur in Gardner's and other collections. Among numbered spe- 
cimens I would refer to this species n. 1263 of Gardner, 2810 of 
Blanchet. from Brazil, and n. 628, 346, 576 of Sir Robert Schomburgk 
(corresponding to n. 968, 560, and 845 of his brother Richard) from 
Guiana; the two last numbers indicate a variety with narrower and 
more elliptical leaves, rather less coriaceous, yet evidently belonging to 
the same species, 
4. H. montanum (A. Juss. in St. Hil. Fl. Bras. Mer. vol. ii. p. 90); 
foliis sessilibus obovatis, inflorescentia folio breviore, pedunculis 
hirtellis, petalis glabris. 
In the district of Minas Geraes, near Itambé (A. de St. Hil). I 
have not seen this species, but it must be very near the common H. 
floribundum, of which it is said to have in every respect the flowers, 
except that they are one-third smaller. 
5. H. obovatum (Benth. in Lond. Journ. Bot. vol. ii. p. 373); foliis 
subsessilibus obovatis obtusis retusisve subtus ramulis inflorescentia- 
que hirsutis, cymis pedunculatis, petalis extus pubescentibus, antheris 
glabris, ovarii loculis uniovulatis. 
In British Guiana (Rob. Schomburgk, 2nd coll. n. 166 and 825, 
Rich. Schomb. n. 135 and 1359). The leaves vary in size almost as 
much as in H. floribundum, from which this species differs in its hairi- 
ness, in the flowers very much smaller (scarcely above one line long), — 
in the stamens only very shortly connate at the base, the ovary globose, 
somewhat depressed, the style short, and the ovules solitary in each 
cell, not two together as I. had formerly by mistake described them. 
6. H. cuspidatum, sp. n.; foliis ovatis oblongisve longe cuspidatis 
serratis ramisque glabris, cymis laxis hirtellis, petalis extus hirtis, - 
ovarii loculis uniovulatis—Ramuli graciles. Folia 3—4 poll. longa, - 
1-13 poll. lata, cuspide semipollicari, serraturis marginalibus sub- 
callosis, adulta crassa coriacea, petiolo brevi dilatato. Cyme axillares 
v. laterales, peduneulo compresso fere pollicari floribus quam in cæte- 
ris speciebus magis dissitis, pube parca vix nisi ope lentis conspicua. 
Flores 1i lin. longi. Filamenta glabra, basi breviter connata, omnia 
integra. Anthere basi brevissime ciliate. Sguamæ hypogynæ 10, 
distinctæ, emarginate. Ovarium. depresso-globosum, stylo brevi 
crasso.
