1905] ELMER—NEW WESTERN PLANTS 51 
branching above the middle and bearing few-flowered cymes: leaves 
clustered at the base, longer ones 6°™ long, covered with a silky- 
velvety pubescence, usually with a petiole 2°™ long; stipules 15™™ 
long, adnate and conduplicate, the interior surface quite smooth, 
terminating in a laciniate pubescent segment 5™™ long; those of the 
smaller cauline leaves broader, larger lobed, and nearly clasping the 
stem; leaflets of the lower leaves 8-12 pairs, densely silky pubescent on 
both sides, 5™™ long, fully that in width, sessile, merely 3—5-pointed, 
the lower one or two pairs somewhat distant, those above the middle 
more or less crowded and diminishing in size toward the apex: inflor- 
escence loosely cymose: flowers short or longer pedunculate, sub- 
tended by leaf-like bracts: hypanthium cup-shaped, 5™™ broad 
and 5™™ high including the teeth nearly 2™™ long; calyx bracts in 
two series of 5 segments each, the outer shorter and narrower, the 
inner 3™™ long and acute: stamens 10; filaments acuminate, nearly 
glabrous, 2”™ long and slightly unequal in length, petaloid in color, 
flattened especially toward the base; those opposite the petals much 
shorter than the others which are exceeded by the longer calyx seg- 
ments; anthers 1™™ long, introrse and basifixed: petals alternating 
with the outer series of stamens, cuneate or oblong to obovate, 3-4™™ 
long, 2™™ wide, barely exceeding the longer of the calyx segments; 
between the base of filaments and receptacle proper a narrow dark- 
brown smooth circular band: receptacle ciliate, ovoid to conical: 
pistils smooth, numerous, sessile; style 3™™ long, erect, straight, 
constricted or articulated to the ovary; achenes 1™™ long, brown, 
semi-recurved. 
Dry gravelly flat near Griffin’s postoffice, Ventura county, California, July 
1902. Type specimen, no. 3971, in Herb. Stanford University. Named in honor 
of P. A. RYDBERG. 
Castilleia gleasoni, n. sp.—Perennial, 2-4°™ high, from a hollow 
thick dwarfed woody base: stems mainly from the base, branched at 
the middle, obscurely ridged or striate, clothed with a soft pilose 
pubescence which conceals the more or less dry glandular surface; 
branches usually clustered from the distal ends of the abruptly 
- terminated stems, striate, similarly pubescent and glandular, bearing 
erect or sub-flexuose spicate racemes 1°™ long: leaves many but not 
crowded, all cauline and equally distributed; larger ones 4.5°™ long, 
12°™ wide, 3-5-nerved, the pubescence on both sides concealing the
