petioles 2 to 2.5 cm. long, slender, glabrous or nearly, so. Racemes 
axillary or from axils of fallen leaves, few-flowered, 10 cm. long or less, 
glabrous or slightly pubescent. Flowers white, the pedicels 1 cm. long, 
densely appressed sericeous. Sepals 5, lanceolate, acuminate, 8 to 9 mm. 
long, 2.5 mm. wide, appressed silvery pubescent outside. Petals oblong, 
equaling the sepals, very densely silvery appressed, sericeous throughout, 
the apex cleft into 5 to 7 linear laciniae 2 mm. long. Stamens 20 ; 
filaments 2.5 mm. long; anthers linear 3 mm. long, one cell with a 
short mucro less than 0.5 mm. long. Ovary ovoid, densely sericeous, 
3-celled; style 5 mm. long. Fruit elliptical or oblong-ovoid 1 to 1.3 
cm. long, dark blue when mature, 1-celled, 1-seeded, the pericarp slightly 
fleshy. 
In forests at 900 m. alt. (No. 5582) type, also (No. 5616) from the same alti- 
tude and at 1,600 m. alt. (No. 4427 Merritt), June, 1906. 
Elaeocarpus sp. 
In forests at 1,300 and 1,600 m. alt. (Nos. 4387, 4409 Merritt ) June, 1906. The 
specimens are with fruit only and apparently represent an undescribed species. 
Elaeocarpus sp. 
In forests at 700 m. alt. (No. 6148). Specimen with fruit only, but quite 
distinct from any of the genera at present represented in our herbarium.

Halconia involucrata Merrill n. sp. 
1 A tree about 8 m. high, the branches terete, brownish gray, glabrous, 
the younger parts stellate-lepidote pubescent. Leaves oblong, subcoria- 
ceous, 7 to 10 cm. long, 3.5 to 5 cm. wide, slightly stellate pubescent 
above, beneath pale and densely minutely lepidote and with scattered 
stellate hairs, the margins subentire or slightly crenate, the apex acute 
or rounded, the base rounded or slightly cordate, strongly 3-nerved, the 
lateral nerves very prominent beneath, ascending, including the basal 
ones 4 to 5 on each side of the midrib ; petioles 1 to 2.5 cm. long. Cymes 
axillary 14 cm. long or less, few-flowered, the flowers in groups of 
threes at the ends of the ultimate branchlets, each group subtended by 
6, oblong, stellate-lepidote bracteoles. Sepals 4, free, elliptical-oblong, 
ultimately nearly 1 cm. long, densely lepidote-stellate. Petals 4, oblong.
