20 Muhlenbergia, Volume 9g 
coarsely dentate; upper leaflets longer and narrower, attenuate 
at both ends, not variable like those of ca¢alinae; lower petioles 
2 to 3cm. long, upper much shorter, about 5 mm. long; stipules 
lanceolate below to broadly ovate above, lobes more or less 
notched and terminated by a long acumination: heads globose 
to ovate, pedunculate, terminal or subterminal: peduncles 3mm. 
to 5cm. long: flowers deep purple: calyx tube 1.5mm. long, 
teeth 4.5mm. long: corolla extending beyond the teeth 2mm. 
vexillum elliptical, obtuse, 9.5mm. long, 2.5mm. wide, very 
finely erose dentate at the apex: ovary 2-ovuled, ciliate with 
long hairs: style 5 mm. long: mature legume and seed not seen. 
The type is in the herbarium of P. B. Kennedy, and a co- 
type in the U. S. National Herbarium. In some of its charac- 
ters this species resembles azchotomum, Macraei and catalinae. 
Trifolium pseudo-albopurpureum sp. nov. 
A somewhat pubescent annual about a foot high, branch- 
ing directly or dichotomously from the base, with obovate or 
oblanceolate leaflets and small, ovate or ovate-conical peduncu- 
late heads. It resembles Wacraez in the character of the florets, 
and albopurpureum in having long peduncles. The species was 
collected by myself along the railroad track near Surf, and at 
Santa Rosa ranch near Lompoc, Santa Barbara county, Califor- 
nia. It in no way resembles xeo/agopus, although that is abund- 
ant in Southern California. The calvx tube and teeth are of 
equal length. 
Annual, with a close appressed pubescence throughout not 
readily apparent except under a lens: stems branching from the 
base upwards, 2 dm. high: basal leaves few and small, soon dry- 
ing up, obovate-cuneate; upper leaflets oblanceolate, inargins 
entire below and erose dentate emarginate toward the apex, 
20mm. long, 7mm. wide; petioles of some of the central leaves 
4 to 6cm. long, others much shorter; stipules membranaceous, 
prominently veined, lanceolate below to broadly obovate above, 
lobes with sharp acumination, ciliate on the margins, mostly 
entire or undulate: internodes of main branches about 6 cm. 
long, of lateral branches much shorter: flowers not showy, pur-
