86 New Species of California Plants. [ ZOE 
inwards and are bounded on each side by a deep bright yellow 
fold which extends down the tube to a little above the insertion 
of the stamens and when spread out is as wide as the divisions, 
Stamens and stigma exserted, the latter surpassing the former 
and declined onto the folds; stigma white, peltate 3 mm. in 
diameter. Stamens didymous, the upper pair slightly longer 
than the lower, inserted equally on the corolla tube about 5 mm. 
above the base, not dilated at base. Anthers yellow, horseshoe 
shaped with rounded or emarginate apex and the bases sharply 
mucronate, clothed with long, curly, white hairs. Ovary oblong, 
tinged with violet. Immature seeds globular, papillose. 
This beautiful Aphyllon was collected by the author on Vision 
Hill, west of Tomales Bay September 1, 1900. It was parasitic 
on Grindelia. It belongs to the same group as A. comosum Gray 
and A. Californicum Gray. It may be one of the forms included 
under the former species but it is unlike the figure of the type 
and none of the descriptions allude to the prominent yellow folds 
on the lower lip. The description was drawn from the living 
plants. 
Asclepias Kotolo, ‘Tall and stout, about 1 m. in height, 
the simple stems hollow and cylindrical, 15 mm. in diameter near 
the base. Leaves opposite, ternate or rarely quaternate, 10-25 
em. long, 5-8 cm. wide, oblong; cordate truncate or cuneate at 
base; the apex obtuse, acute or acuminate and mucronate; mar- 
gins entire or somewhat sinuate: coriaceous, canescent with soft, 
velvety tomentum, the upper surface of the leaves becoming 
smoother with age; midrib broad with the chief veins and reticu- 
lations noticeable under the tomentum; petioles thick from almost 
none to about 1 cm. long, 5 mm. broad, with the upper surface 
concave. Umbels when in flower near the top of the stem but in 
fruit appearing about the middle, owing to the growth of the 
upper stem; involucral bracts linear-lanceolate, varying from 
5-20 mm.in length. Flowers fragrant, 30 or more in each umbel, 
on pedicels 2-4 cm. in length, which in fruit become stouter and 
longer. Sepals and petals reflexed, the former green with the 
outer surface densely tomentose, the inner glabrous except near 
the apex, ovate-acuminate to oblong, unequal, 2-3 mm. long.
