102 NOTES ON HUMIRIACES. 
Spruce, who states it to be a tree of 20 feet, with green sweet-scented 
flowers. 
7. H. subcrenatum (Benth in Lond. Journ. Bot. vol. ii. p. 374) ; ramulis 
hirtellis, foliis subsessilibus ovatis obtuse acuminatis suberenatis basi 
cuneatis, cymis paucifloris, petalis extus puberulis.—olia 1-13- 
pollicaria. 
I described this from a specimen in Sir W. Hooker's herbarium, 
gathered by Martin in Cayenne. I have not had an opportunity of 
re-examining it to ascertain whether the ovary has really one or two 
ovules in each cell. 
8. H. dentatum (Casar. Nov. Stirp. Bras. p. 39); foliis breviter pe- 
tiolatis ovato-lanceolatis dentatis supra glabratis nitidis subtus una 
cum petiolis pedunculis ramulisque puberulis, corymbis axillaribus 
folio brevioribus, petalis glabris.—rwfez arborescens. Folia 3-4 
poll longa, 13-2 poll. lata, in petiolum 3—4-linearem attenuata. 
Stamina glabra, filamenta vix ima basi inter se coalita. 
From the sandy maritime woods called restingas in the province of 
Rio de Janeiro (Casaretto). Unknown to me, but evidently a distinct 
species. 
9. H. (Houmiri) balsamiferum (Aubl. Pl. Gui. p. 564. t. 225); gla- 
brum, foliis sessilibus ovatis v. ovali-oblongis basi latis semiamplexi- 
caulibus. ; 
Said by Aublet to grow in all the forests of French Guiana. From 
his figure and deseription it is evidently very different in the shape of 
the leaf from any species known to me. 
§ 2. Filamentis 5 majoribus cum petalis allernantibus apice tridentatis 
triantheriferis.— Ovarii loculi uniovulati. 
10. H. macrophyllum, sp. n.; glaberrimum, foliis oblongis ellipticisve 
acuminatis vix crenatis, cymis multifloris pedunculatis floribusque 
glaberrimis.—Folia majora semipedalia, 2-23 poll. lata, acumine 
brevi latiusculo, crasso-coriacea, rete venularum parum conspicuo, 
petiolo 3-6 lin. longo complanato. Cyme fastigiate, densiflore, 
circa pollicem latz, pedunculo 1-1}-pollicari, compresso. Flores 
2 lin. longi. Filamenta. fere ad medium connata, 5 majora apice 
trifida, anthera centrali iis staminum simplicium simili, lateralibus 
paulo minoribus sed pariter locelliferis. Ovarium depresso-globosum, 
ovulis solitariis pendulis.
