in the axils, shorter than the leaves, weak and slender, rather 
loosely flowered; pedicels 1 to 1.5 mm. long, very stout, divaricate, 
articulated and leaving prominent broad scars; calyx puberulent, 
broadly turbinate, 2 mm. long, shallowly lobed, the lobes broadly 
semicircular; petals orbicular, 1.5 mm. long; fruit not seen. 
Between Guanai and Tipuani, Apr—June, 1892 (1465). Col- 
lected also by Pearce at Chailla, alt. 3,000 ft. 
PRUNUS GUANAIENSIS sp. n. (Sect. Padus). 
Branches reddish, slender, the internodes about 2 cm. long; 
petioles 1—-1.5 cm. long, stout; blades 1-1.5 dm. long, 3-6 cm. 
broad, ovate, the base rounded, the apex slightly pointed, entire, 
sharply revolute, coriaceous, deep green, drying brown, glabrous 
both sides, shining a the midrib channelled above, promi- 
nent underneath, veins phon or the 7—10 pair of primaries, al- 
ternating with as many short intermediate ones, slightly sre 
nent underneath, obscurely anastomosing near th 
racemes solitary in the axils, distinctly but variably peduncled, 
about half the length of the leaves, very slender and loosely flow 
ered; pedicels 5 mm. long, very slender, pendulous ; diye 
hemispherical, 1 mm. deep, 2 mm. broad, the teeth triangular ; 
pee orbicular, scarcely 1 mm. long; fruit (dry) globose, broader 
one way, about I cm. in diameter, the surface deep reddish-brown, 
dull, loni itiucudy reticulate. 
Between Guanai and Tipuani, Apr.-June, 1892 (1432). Very 
distinct from the last in form and color of leaves and in all the in- 
florescence characters 
Rubus megalococcus Focke, Abhand. Nat. Gesell. Brem. 4: 157. 
Vic. Sorata, Nov., 1892 (1618)—Rusby's 470 and 472 and 
Mandon's 662. 
Rubus roseus Poir. Encyc. 6: 265. Vic. Sorata, 8,000 ft., Nov., 1892 
(1617, as to those specimens with strongly angled stem, prickly 
peduncles and rhachis, and few flowers)—Mandon's 659 and 
661. This yields a nearly fleshless bony bitter inedible 
blackberry, and is in herbaria confused with the next. It ap- 
pears to me identical with R. Mandoni Focke. 
Rubus Bogotensis H. B. K. Nov. Gen. 4: 158. Vic. Sorata, 8,000 
ft, Nov., 1892. The same as Triana’s no. 4189 from New 
Grenada. No. 684, previously enumerated as R. Bogotensis, is 
distinct and is the equivalent of Rusby’s no. 474 and Man- 
don’s 657. 
Osteomeles pernettyoides (Wedd.) Britton, Bull. Torr. Bot. Club 16:
