PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 109 
There are the following additional specimens: 
Costa Rica: IrazG Volcano, flowers, March, 1894, J. D. Smith 4772. Potrero 
del Alto, Pofis Volcano, January, 1888, Pittier (Inst. Fis. Geogr. Costa 
Rica, no. 326). 
Otto Kuntze identified his specimens as Osteomeles heterophylla Ruiz & Pav., 
a species figured in the yet unpublished volume 4 of the Flora Peruviana.* 
This I have not seen, but considering the fact that the known small-leaved 
species of Osteomeles all have rather reduced areas of dispersion, I feel doubt- 
ful about this determination. On the other hand, Captain John Donnell Smith 
considered the specimens collected by himself and the writer to be Osteomeles 
pernettyoides (Wedd.) Decaisne, which is perhaps nearer the truth, since 
this species is known to reach the northernmost end of the Central Cordillera 
of Colombia, in the Paéramo de Tolima, separated from the high Costa Rican 
mountains only by the Isthmian gap. But in our specimens the leaves are 
mostly obovate or oblong and seldom if ever lanceolate, the corymbs are few- 
flowered, with the rachis densely glandular-hairy and not simply villosulous, 
and the calyx segments, standing far apart, could hardly be called triangular- 
subulate. 
Osteomeles pachyphylla Pittier, sp. nov. Figure 48, 
A low, procumbent, spinescent shrub, the young branchlets ferruginous scaly 
pubescent and glandular. 
Leaves alternate or subopposite; petioles 1 to 3.5 mm. long; blades coriaceous, 
thick, suborbicular to ovate, rounded-attenuate or subemarginate at the base, 
acute at the apex, 10 to 24 mm. long, 5 to 18 mm. broad, 
glabrous (or minutely pubescent above on the costa), 
reticulate and lustrous above, paler and _ beautifully 
reticulate beneath; venation impressed above, prominu- 
lous and of a darker color beneath; angle of the main 
veins about 56 degrees; margin sinuate-toothed, thickened 
all around the blade, the teeth glandular. Stipules lanceo- 
late, concave, scarious, brownish, puberulous, caducous te 
or subpersistent, 2 to 5 mm. long. Fia. 48.—Leaf of Os- 
Corymbs shorter than the leaves, subsessile. Bracts teomeles pachy- 
apiculate, broadened at the base, glandular at the tip, phyla. From type 
more or less setulose-hairy on the lower half, 3 to 5.5 mm. specimen. 
long. Pedicels more or less ferruginous-hairy, 2 to 3 mm. 
long. Flowers about 8.5 mm. long. Receptacle ovoid, glabrous or sparsely 
pilosulous. Calyx lobes triangular-acuminate, 1.2 to 2.8 mm. long, glabrous 
or sparsely villosulous. Petals orbicular, concave, pinkish white, 3.5 to 3.8 
mm. long, 3.2 to 3.6 mm. broad. Stamens connate at the base, 4 to 5 mm, long, 
the filaments slender, the anthers purplish, ovoid, longer than broad. Disk 
ferruginous-villosulous. Ovules 5, anatropous; styles terete, slender, about 
5 mm. long, woolly at the base; stigmas bilobulate. 
Fruit not seen. 
Type in the U. S. National Herbarium, no. 531379, collected on rocky ledges 
of the Pf&ramo de Buena Vista, Huila Group, Central Cordillera of Colombia, 
at an altitude of about 3,600 meters, in flower, January 25, 1906, by H. Pit- 
tier (no. 1183). 
Closely related to Osteomeles pernettyoides glauca Decaisne, but differing 
in the glandular, scaly, ferruginous pubescence, the thick, coriaceous leaves, etc. 
In prefloration, the filaments are inflexed-geniculate and the anthers crowded, 
apex downward, around the styles.
