JACQUEMONTIA PALMERI Watson, var. varians. Twining 
stems 1 m. long; leaves cordate, broadly ovate, acute to mucro- 
nate, sessile, or with a petiole 3 cm. long; larger peduncles 10 
cm. long, 5-flowered, otherwise resembling the type, é 
The broad, oval leaves, usually sessile or nearly so, and the 
long, twining stems give to the planta very different appearance 
from that of the small upright forms growing without protection 
of other larger vegetation, The large plants seem to be the re- 
sult of abundant rains and a shaded place of growth. Common 
along western slopes of Cape Region Mts., with the form similar 
to Dr. Palmer’s Guaymas specimens, 
Bignonia Californica. Stems climbing over trees, in cross- 
section representing a Maltese cross; leaflets 2, chartaceous, 
glabrous above, slightly pubescent on veins below, ovate-acumi- 
nate, slightly cordate, 3-4 cm. wide, 6-8 cm. long, conspicuously 
pinnate-veined; petiolules 4-10 mm. long, petioles 1-2 cm. long, 
more or less pubescent; flowers on one or two axillary peduncles 
about 5 cm. long that may be branched near the middle so as to 
be 2-3 flowered; calyx broadly campanulate, 10-15 mm. long and 
wide, margin undulate; corolla bright yellow, glabrous without, 
slightly pubescent within, 4-5 cm. long, the lobes spreading 3
