In the original description the word “glabrous” as applied 
to the stem and leaves is misleading. The upper surface of the 
leaves appeaasr as if glabrous, but is distinctly pubescent under a 
lens. Also the expression “naked peduncles” should be ap- 
pressed pubescent under a lens. 
Trifolium insularum sp. nov. 
An erect annual somewhat resembling olzvaceum, with in- 
conspicusus purple flowers and long rigid teeth. It seems to 
have been collected only on Catalina island, California, which is 
far removed from any known station for o/zvaceum, its nearest 
relative. It has been called catalinae, but differs very materially 
from the type of that species in having heads with long pedun- 
cles, long calyx teeth and inconspicuous flowers. 
The type, in the herbarium of the Missouri Botanical Gar- 
den, was collected by Mrs. Trask in May, 1897, with the state- 
ment that it occurs in three localities, two in canyons and one 
by the edge of the sea. 
Annual, erect, about a foot high, branched from the base, 
pubescent throughout: lowest leaflets cuneate to obovate, on 
petioles 3cm. long; upper leaves elliptical, margins coarsely 
dentate; stipules ovate-lanceolate with a long apiculation, mem- 
branaceous, g abrous below but somewhat hairy above: inter- 
nodes 5 to 8cm. long: peduncles 3 to rocm. long: flowers incon- 
spicuous. purple: calyx tube 2mm., teeth 6mm., hirsute rather 
than plumose and somewhat rigid: corolla extending 34 the 
length of the teeth; vexillum 7.5mm. long, 1.7mm. wide, ellip- 
tical: ovary 2-ovuled: style 3mm. long, narrow: legume 3 mm. 
long, 1.8mm. wide, membranaceous, glabrous, 1-seeded: seeds 
dark brown, not mottled, narrowly oblong, 2 mm. long.
