47. COMPOSITACE-E. 
scales and ped. of extreme forms, such as the original type of 
C. comata in BH., give that var. a most distinct and peculiar 
aspect. It passes however gradually hack through ft, which 
seems to he the normal or average form of the sp., into the 
other almost eglandulose or comparatively denuded maritime 
state a , — the main distinctive characters of all three in com- 
mon being the peculiar light shining apple-gr. foliage, the 
mostly low habit branched from the base, the mealy-cottony - 
puberulous ped. and inv., the peculiar deep-black setules or 
hairs, the pale or lemon-y. fl. and small narrow heads of few 
lax florets more like those of a Hieracium than of most Crepkles. 
The 1. vary from undivided to runcinato-pinnatifid in each of 
the three forms. 
The following description, taken June 10th 1830, from pi. of 
ft growing in my garden at the Valle, brought in the previous 
Sept, from high up the Rib. de S. Jorge, is here subjoined 
principally to help in forming a comparative opinion concern- 
ing the doubtful C. andryaloides : — 
Root at least bienn. as thick as the forefinger, nearly simple 
tapshaped brown or whitish, 8 or 10 in. long wrinkled con- 
centrically upwards. St. single about 2 ft. high fistulose stout 
erect very straight, slightly but very obtusely angular, even, 
thick in proportion to its side-branches which are produced all 
the wav up from nearly the base, more or less bristly through- 
out with short distinct patent (not glandular) hairs or setns, 
occasionally but rarely nearly smooth. From the shortness of 
the side-branches in proportion to the main st. and the wide- 
spreading lower 1. the whole pi. forms an oblong or cvliudric 
bush broad in proportion to its height. Side-branches erecto- 
patent slender subangular or striated leafy like the main st. to 
the top with a single leaf at each fork or axil and terminating 
like it in a loose subirregular cyme of from 3 to 0 or 8 fl., and 
hispid more and more upwards with short glandular black or 
blackish aculeiform setules. L. all of a peculiar pale bright 
yellowish gr. with a whitish conspicuous midrib and of a thin 
membranous substance, all quite smooth and shining except 
the midrib beneath in all and edges in the upper 1. which are 
more or less sprinkled or fringed witli hairs or setules. Root- 
1. in a radiating tuft elongate lanceolate-oblong acute much 
attenuated downwards into their petioles 0-12 in. long, 1-2 
broad near the point; st.-l. oblong-acuminate cordate and lialf- 
amplexicaul at the base, one at each fork or axil, the upper 
gradually smaller and more linear, the margins of all except the
