SOME MINOR GENERA 313 
CreEpIs (classical name for a plant mentioned by Pliny, but not de- 
szribed). A genus comprising about one hundred and thirty species, of 
* _ which half a dozen are British, and known as Hawk’s-beards. The leaves, 
which are chiefly radical, are very similar to those of the Common Dande- 
lion, which the flower-heads also resemble. The florets are all strap-shaped, 
and the involucral bracts are slender, mostly equal in size, but with a few 
smaller ones at their base. Only two species are in cultivation, viz. 
Crepis awrea, a perennial with orange flower-heads, the involucre and 
flower-stalk covered with long black and small white hairs. It varies 
from 4 inches to a foot high, and flowers in autumn. Introduced from 
the Italian Alps (1739). C. rubra, an annual, has purple, rosy, Or white 
flower-heads, and bristly involucre; in other respects it is similar to 
C. aurea. Introduced from Italy (1632). C. awrea is propagated by 
seeds or divisions in spring; C. rubra by seeds. They oa a soil that 
is sandy. 
Hirractum (Greek, ierav, a hawk). Hawkweeds. A genus of 
about one hundred and fifty perennial herbs, with many unequal involucral 
bracts. Florets all strap-shaped, yellow or orange. Several species are 
native, and the only one cultivated is naturalised locally in the North. 
This is Hieraciwm awrantiacum (“ Grim-the-Collier ”) with creeping root- 
stock, entire elliptical leaves and orange-red flower-heads in corymbs ; 
June and July. It is propagated by dividing the rootstock in spring, or 
by sowing seeds at the same period. 
PODACHANIUM is represented 1 in our hothouses by a plant commonly 
known as Ferdinanda eminens, but which is correctly named Podach- 
enium paniculatum. It isa tall shrub, 10 or 12 feet high, with large, 
opposite angular-lobed leaves, a foot or 18 inches long, and small white 
flowers, grouped in large panicles. As it forms large clumps it should 
only be grown in large houses, and may be turned outside in summer 
time. A compost of loam and peat suits it best; it is propagated by 
cuttings taken in spring, and inserted in sandy soil, covered with a bell- 
glass and struck in heat. 
PALAFOXIA (named in honour of a Spanish general, José Palafox, 
1780-1847). A small genus—about half a dozen species—of erect herbs, 
natives of Mexico and Florida, with narrow, alternate leaves, and flower- 
heads in panicled corymbs. Only two species are of horticultural 
interest :—Palafoxia hookeriana and P. linearis, plants about 2 feet 
high. P. hookeriana has slender lance-shaped leaves, and loose clusters 
of rosy-pink flowers; June to August. P. linearis is of more shrubby
