(no. 13693).

This species in the shape and size of its fruit suggests 7. densiflora, but it has fewer 
and larger leaflets.

Tall woody vines; leaflets 3, broadly ovate, acuminate, 6 to 10 cm. long, early 
glabrate, slightly reticulated; inflorescence somewhat pubescent; pedicels 10 mm. or 
less long; calyx tube short and broad, the lobes ciliate; the upper lobe broad and

Robinia pringlei Rose, sp. nov. 
A medium-sized, apparently spineless tree; young branches with short, appressed, 
often scanty pubescence; young leaves with dense, silky, brownish pubescence; 
mature leaves 20 to 30 cm. long; leaflets 13 to 15, shortly oblong, 4 to 6 em. long, 
rounded at base or broadly cuneate, rounded at apex, paler beneath, scantily pubes- 
cent on both surfaces; racemes 10 to 15 em. long; pedicels 10 to 12 mm. long; calyx 
tube broad, the upper lip notched, the lower lip 3-lobed; pod 3 to 6 em. long. 
Collected by C. G. Pringle in valley near Tula, State of Mexico, altitude 19 to 40

LINACEAE. 
A NEW SPECIES OF LINUM. 
Linum lasiocarpum Rose, sp. nov. 
Annual, simple or more or less branched, 1.5 to 30 em. high, slender, glabrous 
except some hairs in the inflorescence; lower leaves generally in whorls, obovate, 
10 mm. or less long, obtuse, entire, not at all glandular ; upper leaves opposite or 
alternate, narrower, sometimes acute, rarely toothed ; pedicels very short, 1 mm. or 
less long, densely pilose ; sepals lanceolate, acute, with gland-bearing margins, the 
three nerves prominent and wing-like; petals yellow, 4 mm. long; styles distinct to 
the base; carpels pilose. 
Collected by C. G. Pringle near Monterey, April 15, 1906 (no, 10209). 
Near L cruciatum, but leaves not glandular-serrate and the sepals more strongly 
nerved.
