CACALIA. 
C 
Cacalia makes up a group of American Composites which as a 
rule are singularly useless and unpleasing weeds. The one interesting 
species of which we hear is C. calva, a most curious plant having 
exactly the port and foliage of a very finely-cut-leaved Anemone 
narcissiflora, and producing also white flowers in umbels of pretty much 
the same appearance. C. calva is an alpine from the high mountains 
of Mexico, and should be hardy in a warm, well-drained, and sheltered 
place, with perhaps a little protection if the winter proves especially 
raw and cold. The rest of the Cacalias come indistinguishably close 
under Senecio, in which they are often included ; and have all the 
faults of that huge and often hideous race. 
Caccinia, a race of Borrages from the mountains of Persia, de- 
lighting in hot sandy soil. C. glauca has notably attractive blue-grey 
oval foliage, fat and metallic, set with bristles; and long flopping 
stems beset with stars of violet blue flowers that make a fine har- 
mony with the leaves, as they pass through their different shades of 
purple towards pink. Even more beautiful, and perhaps more cer- 
tainly hardy, might prove C. strigosa, which has the same habit, but 
longer flowers of a very intense azure ; while C: Rauwolfii has narrower 
foliage, and blossoms of a purer blue. All the species have the same 
alluring fat glaucous foliage, and all are to be raised from seed. 
C. Kotschyi is yet another. 
Cachrys, an uninteresting fine-leaved family of small Umbel- 
lifers, after the fashion and with the needs of Athamanta. 
Calamintha now shows a tendency to retreat under the shadow 
of Satureja, but the gardener may still have occasion, under its older 
name, to order the great alpine Calaminth, which makes so splendid a 
show in July and August, in a weakly ascending mass of 6- or 8-inch 
stems, each ending in violet and white-lipped flowers. Very much 
more choice and delightful, however, is C. grandiflora, a variety of the 
last, far more splendid in size and colour of blossom, and rather more 
decumbent in habit ; it may be seen in violet sheets on the roadside 
rocks at the top of the Mont Cenis Pass, and answers easily to the same 
quite ordinary treatment that suits its type. 
Calandrinia, a family of North-American Portulacas, of which 
only about two hover on the edge of being satisfactory in the rock- 
gardens of England, and those only if kept in very poor soil, dry and 
pebbly, in the fullest exposure to sun and nothing else. These are: 
C. pygmaea, by far the more valuable species—a minute rock
