ubove (the pubescence much denser on the costa), pale, prominulous-reticulate, 
and sparsely pilosulous beneath, glandular-serrulate ex- 
cept at the base. Stipules acute, grayish-pubescent, 1 to 5

specimen. hardly over 1 mm, long. Flowers about 7.5 mm. long. 
Receptacle broadly obconical, sparsely grayish-pubescent. 
Calyx segments triangular-apiculate, broad and sparsely tomentose at the base,

Type in the U. 8. National Herbarium, no. 533720, collected in the Cordillera 
de Santa Marta, Colombia, at an altitude of about 2,750 meters, January, 1898- 
1901, in flower, by H. H. Smith (no. 1751). 
Distributed under the name of Osteomeles oblongifolia Lindl., which, however, 
did not exist previously. Intermediate between the large-leaved and small- 
leaved species. 
Osteomeles obovata Pittier, sp. nov. Ficunre 47. 
A low, spinescent, erect shrub, the young branchlets glandular and ferruginous- 
hairy. 
Leaves with petioles 2.5 to 5 mm. long; blades obovate or oblong-spatulate, 
cuneate at the base, truncate, rounded, obtuse, or subacute at the apex, 13 to 
28 mm, long, 5 to 10 mm, broad, glabrous, or sparsely 
hairy on the costa, and lustrous above, dull, glabrous, and 
reticulate beneath; venation brown; angle of the primary 
veins about 33 degrees; margin sinuate-serrate, the teeth 
glandular, Stipules hardly more than 2 mm. long, nar- 
row, acute, setaceous, deciduous. 
Corymbs few-flowered (sometimes reduced to one 
flower), much shorter than the leaves, the rachis gland- 
ular and densely ferruginous-hairy. Bracts narrowly 
; teomeles obovata. 
lanceolate, glabrous, 5 mm. long or less. Pedicels 1 to 2 Natural size. From 
mm. long, ferruginous-hairy. Flowers about 5 mm. long. type specimen. 
Receptacle ovoid or subglobose, sparsely villous. Calyx 
lobes acicular, distant, hardly broadened at the base, more or less hairy on the 
lower half, 2 to 2.2 mm, long. Petals flat, broadly ovate or suborbicular, 2.8 
to 8.5 mm. long, 2 to 2.4 mm. broad, contracted at the base into a short claw. 
Stamens glabrous, about 2.4 mm. long, the anthers ovoid, slightly longer than 
broad. Disk cano-tomentose. Styles terete, glabrous, 2.5 to 3.2 mm. long; 
stigma bilobulate.
