Plant Characteristics:
Perennial or subshrub from woody caudex, glabrous to puberulent; stems
trailing or climbing, 1-9 m. long; lvs. triangular, lobes rounded to 2-angled, less than 13 cm. long, greater
than 7 cm. wide; sinus +/- acute to rounded or square; peduncle 1-several-fld.,
generally greater than subtending lf., bractlets 10-20 mm., 6-12 mm. wide,
lanceolate, not or slightly keeled; sepals 9-16 mm.; corolla 2-40 mm., white or
fading pink; ovary chamber 1, stigma lobes 2, generally swollen, cylindric or
oblong, +/- flattened; fr. +/- spheric, +/- inflated; seeds +/- 4.
Habitat:
Coastal slopes, Topatopa, Santa Monica, and Santa Susanna mts., Ventura
Co. to w. Orange Co.; Catalina Id. March-August.
Name:
Greek, kalux, cup and stegos, a covering. (Munz,
Flora So. Calif. 371).
Referring to the bractlets which conceal the calyx of some species.
(Hickman, Ed. 517). Greek, makros, large. (Jaeger
147). Latin, inter, preposition meaning between, among and Latin, medius,
middle. (Jaeger 129,151). Intermedia,
intermediate, probably because the plant falls in between the characteristics of
other subspecies. (my comment). Macrostegia,
refers to the large covering over
the calyx. (John Johnson).
General:
Common on the south facing slope of Newporter Canyon, also found on the
Eastbluff bench. (my comment). Appears
similar to Convolvulus, but anatomy
suggests that the two genera are not very closely related. Intergrades with other ssp.,
probably also with C. piersonii.
(Hickman, Ed. 518).
About 150 species, temperate, worldwide.
(Hickman, Ed. 517)
