168 New Spectres of Lower California Plants. [zor 
Specimens from San Clemente Island are hirsute-pubescent at the 
flowering part of the stems; those from Guadalupe Island are 
nearly glabrous. The Lower California form is noted in Proc, 
Cal. Acad., 2nd Ser. III, 225 as No. 712 G. juncea (Benth). 
CONOBEA INTERMEDIA Gray. Stemodia polystachya Brandg. 
It is found from Comondu to Cape St. Lucas in forms varying 
much in pubescence, some being nearly glabrous. ‘The plants 
are much larger than described, often a foot high, much branched 
and with an indurated root. Purpus, 431. 
Ipomza Tastensis. A glabrous, branching, woody vine with 
stems 10 m. long climbing over bushes and trees, somewhat twin- 
ing; leaves cordate, long-acuminate, 5-6 cm. wide, 6-8 cm. long, 
entire or usually furnished with 2-6 deltoid acuminate teeth 2-5 
mm. long at the place where would be the auricle of a 3-lobed 
leaf ; petioles slender, curved asif used in climbing, 3-6 cm, long; 
peduncles solitary, 2-3 cm. long; pedicels thickened upward, stri- 
ate; corolla white, to-14 cm. long, with narrow funnel-form tube, 
the acuminate lobes spreading 8-10 em.; anthers inserted high in 
the tube, lanate two-thirds their length; calyx lobes lanceolate, 
long-acuminate, 2-5 cm, long, the outer two much shorter; cap- 
sule nearly spheerical 1.5-2 em. in diameter, 2-celled; seeds finely 
pubescent, 
The flowers of this Ipomza are handsomer than those of /. 
Bona-Nox, which they somewhat resemble. It is very abundant 
on the western slope of Sierra El Taste and the large white flow- 
ers are very conspicuous during the early hours of the day. 
Ipomea peninsularis. The slender Stems twining, 1-2 cm. 
long from a tuberous root, retrorsely pubescent; leaves sessile, 
clasping or on pubescent petioles 5-10 mm. long, cordate, ovate- 
acuminate, entire or slightly angulate, 4-6 cm. long, 3-4 cm. 
wide, glabrous or somewhat pubescent, the midrib excurrent, 
sinus narrow, the lobes often overlapping; peduncles 3-6 cm. 
long, 1-3 flowered; corolla funnel-form, pale violet, 15 mm. long, 
spreading 12 mm. wide; sepals ovate, mucronate, 4-5 mm. long, 
coriaceous with brown margins, glandular-muricate: capsule 
Ovate-conical, acute, 2-3 times longer than the sepals, 2-celled; 
seeds 4, pubescent especially upon the angles.
