62 New Species of South American Plants 



In its peculiar inflorescence characters as well as in those of 

 the stamens, this plant appears to represent a distinct genus, but 

 in the absence of fruit, it is tentatively referred to Rinorea. 



Mr. Smith sends another specimen under the same number 

 from the same region, February 25, of which he says: "A tree 

 to 40 feet, common locally in mountain forest, 4000 to 5500 

 feet. Flowers white." This specimen has leaves little more 

 than half as large, closer together and drying of a pale green 

 and the flowers are smaller. 



Hasseltia lateriflora. 



Young petioles, etc., sparsely puberulent, with yellowish 

 hairs. Branchlets stout, terete, whitish or pale, very leafy. 

 Petioles 2 cm. or less long, rather stout, sub-terete, dilated at 

 both ends, 2-glandular at the summit. Blades 9 to 15 cm. 

 long, 3 to 6 cm. broad, oblong or oval, with rounded base and 

 an abrupt and very short blunt point, thick, entire, 3-nerved, 

 the lateral pair starting from the petiole and running near the 

 margin for a little more than half the length, the secondaries 3 

 or 4 on each side, strongly ascending and strongly anastomosing, 

 the venation coarsely anastomosing, prominent on both sides, 

 only slightly so above, where the midrib is slightly grooved. 

 Panicles lateral, in flower, less than half the length of their 

 leaves and shorter than the leaves when in fruit, short-ped- 

 uncled, loosely and slenderly branched, the branches striate or 

 lightly angled, the bracts and bractlets very small, the pedicels 

 slender. Calyx lobed nearly to the base, the lobes 4 mm. long, 

 lanceolate, blunt. Petals resembling the sepals and a little 

 exceeding them. Stamens very numerous, persistent. 



"A tree, to 60 feet, in mountain forest, 4000 to 6000 feet. 

 Collected on Sierra del Libano, 6000 feet, January 21." (Her- 

 bert H. Smith, No. 1915.) 



A specimen collected by Traill, on the Purus, is very similar, 

 if not identical as to species. 



Casearia (Pitumba) onacaensis. 



Inflorescence minutely puberulent. Branchlets slender, ter- 

 ete, purplish, the internodes about 1.5 cm. long. Petioles 6 

 mm. long. Blades 4 to 8 cm. long, 1.5 to 2 cm. broad, lanceo- 

 late with inequilateral acute base and somewhat abruptly 

 acuminate and obtusish summit, obsoletely serrate, the margin 

 minutely indented, thick, deep-green, minutely pellucid-punc- 

 tate, the strong venation prominent on both surfaces, especially 

 beneath, the secondaries 5 or 6 on a side, strongly falcate- 

 ascending, scarcely connecting, the venaion finely reticulate. 

 Fascicles nearly circular as pressed, about i cm. broad. Pedicels
