ascending or erect, producing an abundance of fleshy roots: leaves 
numerous, oblanceolate, tapering gradually into the long, margined 
base, tapering lanceolately toward the subacute apex also, 2-3 dm. 
long: scapes 4-6 dm. high, few-flowered (1-6), the pedicels very 
unequal: calyx tube obconical, about 5 mm. long; calyx lobes linear- 
lanceolate, longer than the tube: the sinuses broadly rounded: 
corolla lobes lance-linear, one-half longer than the sepals, the tube 
very short: stamens distinct and sessile, stout subulate, as long as 
the sepals: capsule circumscissile near the apex, then splitting at the 
summit only into 5 valves, each of which opens for a shorter distance 
in the dorsal suture, ovoid to oblong, equaling the calyx lobes. 
Among the operculate species, having distinct anthers, I can find none with 
which to compare this large glabrous form. 
MACBRIDE 672, moist flats near the Trinity Lakes, Elmore Co., Idaho, 
August 29, 1g10. 
COLLOMIA GRANDIFLORA axillaris, n. var.—Stems slender, cin- 
erous-puberulent, 3-5 dm. high: leaves puberulent: the capitate 
flower clusters small and few-flowered, on very short foliar-bracted 
branchlets axillary in most or even all of the leaves, the terminal 
cluster often not much larger than the others: calyx very glandular. 
Collomia grandiflora is thus seen to be exceedingly variable. Any one com- 
paring this variety with material typical of the species would have no hesitation 
in declaring them remarkably distinct. But with C. grandiflora diffusa Mul- 
ford before you, and a goodly number of intermediates between the species 
and the varieties, one hesitates to name it at all, So striking a variation, how- 
ever, ought to be designated in some way. 
MACBRIDE 580 is the type; Trinity, Elmore Co., August 8, rgro, open hill- 
sides. Less well represented by his no. 376, Silver City, July 14, 1910, steep 
hillsides. 
Phlox aculeata, n. sp.—Depressed-caespitose on the intricately 
slender-branched caudex: stems slender, sparsely crisped, viscid- 
pubescent, especially above, the internodes short or nearly wanting: 
leaves densely crowded, filiform, straight or curved, rather rigid 
and aculeate, the midrib and margins slightly thickened, obscurely 
puberulent and the uppermost also minutely glandular; usually 
only 10-12 mm. long but often a few of them are a half longer: 
flowers solitary or more often 3-5 at the ends of the branchlets, 
on pedicels 3-7 mm. long: calyx densely glandular-pubescent,
