Coleus—continued. 
they should be allowed to develop their flowers, some of 
which are highly ornamental. Cuttings strike with the 
greatest freedom at almost any time of the year, and, 
with a good moist heat, will quickly form fine specimens. 
They are best placed separately in small pots, and, when 
rooted, may be potted on, allowing a liberal shift each 
time. Coleus may also be increased by seed; but this 
method is only adopted when it is desired to raise new 
varieties. 
С. Verschaffeltii, a variety of О. Віштеї, is much grown 
for bedding purposes, and is especially employed in large 
carpet-bedding designs; it is one of the most effective 
crimson-leaved subjects for the purpose, and, arranged 
with Centaurea or Golden Feather, it is very striking. 
C. barbatus (bearded). ji. brownish, with the lower lip nearly 
ovate, compressed, and hairy; racemes terminal. November. 
ca oval, Realloned. downy and wrinkled, gradually narrowed into 
the footstalk. Stem quadrangular. h. 2ft. Abyssinia. Peren- 
nial. Every part of the plant has a powerful fragrance. SYN. 
Plectranthus barbatus. (А. B. В. 594.) 
C. Blumei (Blume's. /. purple and white, disposed in a 
terminal elongated whorled spike or raceme. 7. rhomboidal ovate, 
membranaceous, deeply and coarsely inciso-serrate at the margin, 
the apex acuminate, entire as well as the base ; yellowish-green 
in colour, the whole disk dark purple or sanguineous, breaking 
into spots near the margin. Л. lft. to 1%. Java. Perennial. 
It is from this species that the innumerable variegated forms 
(so extensively grown for decorative purposes), including Ver- 
schafeitii, have originated. (В. M. 4754.) 
C. inflatus (inflated). jl. lilac, disposed in compound, sub- 
racemose spikes. December. Ё, on long petioles, opposite, 
ovate, sharply acuminated, very coarsely serrated. Stems and 
branches square; thé base of the stem scarcely woody, often 
tinged 0 -colour and spotted with red. А. 3ft. Ceylon.

(Macrae’s). i variegated with white and dark 
Ес dis in a large terminal panicle ; corolla very curious 
? sudden geniculation near the middle of the tube, in the 
ample and compressed throat, and especially in the large boat- 
shaped lower lip. Summer. /. ovate, acuminate, serrated, dark

C. scutellarioides {Soutellarts-like) Л. blue, with the lower 
lip white and quadrifid ; disposed in verticillate racemes. Z lan- 
ceolate-ovate, serrate, light green above, underneath brownish, 
аз is also the stem. East Indies, North Australia, &c. A tall 
herb or under-shrub. SYN. Ocimum scutellarioides. (B. M. 1446.) 
The varieties of this genus are innumerable, and a 
number are added each year. The following is a selection 
of the best kinds now in cultivation; the descriptions refer 
to the leaves: :

COLLETIA (named after Philibert Collet, a French 
botanical writer, 1643-1718) ORD. Rhamnew. Mauch- 
branched greenhouse or half-hardy shrubs. Petals absent, 
or very minute; calyx campanulate, coloured. Leaves, 
when present, simple, opposite, stipulate, deciduous, very 
minute, entire. Branches divaricating, decussately oppo- 
site; branchlets spiny. They are extremely curious plants, 
and are best grown in sheltered, isolated positions, where 
their peculiar character can be readily seen. A good loamy 
soil is most suitable. Cuttings of half-ripened wood, 6in.

to 8in. in length, will root readily in well-drained pots 
of sandy soil, in a cool greenhouse; they should then be 
placed in a close, cold frame, until fully established.

C. Bictonensis (Bicton) A synonym of C. eruciata. 
С. cruciata (cruciform). jl. solitary. l very few, elli tic, quite 
entire. Stem very prickly; spines decussate, compresse laterally, 
broad, ovate acute, decurrent. h. 4ft. Rio de la Plata, 1824,

filaments elongated, exserted. May to July. 1. elliptic, quite 
entire; spines very strong, awl-shaped. h. 3ft. to 10ft. Chili 
and Peru, 1823. SYNS. C. armata, C. ferox, C. horrida, C. poly-

COLLIER. A common name of the Black Fly 
(which see). 
COLLINSIA (named after Zaccheus Collins, once 
Vice-President of the Academy of Natural Sciences of 
Philadelphia). ORD. Scrophularineæ. A small genus of 
about a dozen species of very pretty hardy annuals. 
Flowers brightly-coloured; corolla tube saccate at the 
base on the upper side. Leaves entire, opposite, rarely 
verticillate. These are excellent subjects for growing 
in patches and clumps; and are of very easy culture in 
any ordinary garden soil. Seed should be sown in the 
open border, late in March, or in April, and the seed- 
lings thinned out to about 2in. apart. For spring flower- 
ing, the seed should be sown in a sheltered place during 
autumn, and the young plants protected, if necessary, 
during the winter, with a handlight, or matting.
