CERASTIUM. 
C. napuligera is leafy and fluffy, about 9 inches high, each stem 
ending in a specially starry head of blue or red. (From Rhodope and 
Dalmatia.) 
C. pindicola is the same as C. Bourgaei, q.v., with the lower leaves 
undivided. 
C. pulcherrima= Aethiopappus pulcherrimus, q.v. 
C. ragusina, another vast border-plant of towering stature, set with 
stout globes of rayless yellow. 
C. ruthenica rises to about a yard high, with feathered blue-grey 
smooth foliage, and light sulphur-yellow balls of blossom. 
C. Tournefortii, about the same height, is bright-green, hairy, and 
has heads of deep golden-yellow. 
Centranthus. — No aitention need be paid to our own red 
Valerian. Let it be sown in any old wall, and there left to go on 
for ever. Yet finer, though, is C. angustifolius, from very hot and 
stony places of the Southern Alps, with showers of clean and ardent 
coral-rose. 
Cephalaria, a race of most graceful perennials, close to 
Scabiosa, and of tall growth, producing countless large and long- 
stemmed flowers all through the summer, whose various shades of 
sulphur-yellow can make an entrancing effect amid the purples of 
certain Campanulas. All being 4- or 5-foot border-plants, here 
follow their names: CC. alpina (the least overwhelming in height, 
usually about 3 feet), procera, ambrosioeides, dipsacoeides, leucantha, 
radiata, tatarica, and transylvanica—C. tatarica being especially 
remarkable for the luxuriant splendour of its port. 
Cerastium.—tThis unpromising race of weeds does, in point of 
fact, wander high and far into the stoniest places of the mountains, 
and there produces a number of species, most delicate and pure in 
beauty, as well as rather delicate in temper, too, asking for moraine- 
culture if they are truiy to be happy. On the other hand, many of 
them are borderers and edgings of uncontrollable habits and excesses. 
C. alpinum, which is found in the higher summits of Great Britain, 
is a very densely woolly species, paradoxically less easy of culture 
than many of its foreign cousins, as its excessive fluff gets soaked 
too often into rottenness in winter. 
C. Biebersteinti, from the Alps of Taurus, is quite one of the best— 
all pure silver-white in leafage, slightly woollier than C. tomentosum, 
with leaves of narrower oblong form; and, when the show of lovely pure- 
white flowers is done, the fruiting heads always stand erect, instead 
of turning earthwards. 
C. Boissieri, from the south of Europe, is also closely akin to
