the disk within. Calyx lobes triangular-apiculate, the broader base hairy, 
the tips glabrous. Petals glabrous, flat, suborbicular, 3 to 3.6 mm. long and 
broad, attenuate at the base into a broad claw, the margin more or less 
sinuate. Stamens numerous, about 2.5 mm. long, the anthers broader than long. 
Styles thick, clavate, cano-tomentose at the base, about 3 mm, long; stigma 
undivided. 
Fruit not seen. 
Type from Peru. The above description is from specimens in the U. 8. 
National Herbarium, collected by the U. S. Exploring Expedition under the 
command of Capt. Wilkes, and others collected in Peru. 
Osteomeles incerta Pittier, sp. nov. FIGURE 45. 
An unarmed, erect shrub, the old bark grayish. the young branchlets fer- 
ruginous, furfuraceous. 
Leaves alternate (not fasciculate) ; petioles 1 to 5 mm, long; blades coria- 
ceous, rather thick, broadly ovate, subattenuate at the base, obtuse, emargi- 
nate, subacute, or apiculate at the apex, 10 to 25 mm. 
long, 5 to,15 mm. broad, more or less villosulous (princi- 
pally on the costa), lustrous and minutely bullate-reticulate 
above, paler, glabrous or glabrescent, and reticulate be- 
neath; venation impressed above, prominulous beneath ; 
angle of the main primary veins about 60 degrees; margin 
sinuate-serrate, the teeth glandular. Stipules ovate- 
oblong, small, ferruginous-pubescent, caducous. 
Corymbs shorter than the leaves, 3 to 5-flowered, the Fic. 45.—Leat of Os- 
rachis densely ferruginous-pubescent. Bracts lanceolate, teomeles incerta.

attenuate toward the base and broadening again at the in- type specimen. 
sertion, acute at the apex, villosulous, 3 to 7 mm. long or 
over, 0.5 to 1 mm. broad. Pedicels 3 to 5 mm. long, ferruginous-hairy. Flowers 
about 3 mm. long. Receptacle subglobose, more or less pilosulous; calyx 
lobes triangular-apiculate, more or less ferruginous-hairy almost to the apex, 
4 to 4.5 mm. long. Petals broadly ovate, contracted at the base into a very 
short claw, obtuse at the apex, 5 mm. long, 3.5 to 4 mm. broad. Stamens 
glabrous, about 4.5 mm. long, the anthers ovate, about as broad as long. Disk 
brown-woolly. Styles slender, woolly at the base, 4 to 4.5 mm. long; stigmas 
discoid, undivided. 
Fruit not known. 
Type in the U. S. National Herbarium, no. 325749, collected in Bolivia, 
precise locality not stated, by Miguel Bang (no, 1839). 
In the absence of the types or of more precise descriptions, it is extremely 
difficult to name with any degree of certainty any species of Osteomeles. The 
above species agrees in several particulars with the original description of 
O. pernettyoides (Wedd.) Decaisne, but differs also in about as many details. 
The leaves are seldom oblong-lanceolate, generally much larger than in the 
typical form (QO. pernettyoides microphylla), and not glabrous or glaucous 
beneath as in fhe large-leaved form. Although reluctant to do so, I feel 
obliged to place this form under a separate name until a general revision of 
the types can be undertaken. 
Osteomeles intermedia Pittier, sp. nov. FIGure 46. 
An erect, unarmed shrub, the old bark gray, glabrous, sparsely verruculose, 
the young branchlets grayish-pubescent and verruculose-tuberculate. 
Leaves alternate; petioles canaliculate, 4 to 5 mm. long, sparsely grayish- 
pubescent; blades membranous, ovate, oblong, or obovate, rounded or cuneate 
at the base, acute at the apex, 1.5 to 3.5 cm. long, 1 to 1.7 cm. broad, lustrous,
