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. Coleua may also be increased by seed; but thia 

 method is only adopted for raising new varieties. 



C. Verschaffeltii, a variety of C. Blumei, 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, is very striking. 



C. barbatus (bearded). /. brownish, with the lower lip nearly 



ovate, compressed, and hairy ; racemes terminal. November. 



I. oval, scalloped, downy and wrinkled, gradually narrowed into 



the footstalk. Stem quadrangular. A.2ft. Abysinnia. Peren- 



nial. Every part of the plant has a powerful fragrance. (A. B. R. 



594.) SYN. Pleetranthus barbatua. 



C. Blumei (Blume's). fl. white and purple, disposed in a 

 terminal elongated whorled spike or raceme. I. rhomboidal ovate, 

 membranous, 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, breaki

into spots near the margin, h. 1ft. to IJft. Java. Pereni 

 It is from this species that the innumerabe variegated forms 

 (so extensively grown for decorative purposes) including Ver- 

 schaffeltii, have originated. (B. M. 4754.) 



C. Colvillei (Colville's). A synonym of Pleetranthus coleoides. 



C. Inflatus (inflated), jl. lilac, disposed in compound, sub- 

 racemose spikes. December. L on long petioles, opposite, 

 ovate, sharply acuminated, very coarsely serrated. Stems and 

 branches square; the base of the stem scarcely woody, often 

 tinged with orange-colour and spotted with red. h. 3ft Ceylon. 

 Perennial. (B. M. 5236.) 



C. Macrael (Macrae's). /I. variegated with white and dark 

 purple, disposed in a large terminal panicle ; corolla very curious 

 in the sudden geniculation near the middle of the tube, in the 

 ample and compressed throat, and especially in the large boat- 

 shaped lower lip. Summer. I. ovate, acuminate, serrated, dark 

 green above, beneath deeply purple, as are the petioles. Stems 

 quadrangular, dark purple, branched, with opposite branches. 

 h. 2ft. to 3ft. Ceylon, 1852. Perennial. (B. M. 4690.) 



C. scutcllarioides (Scutellaria-like). JL blue, with the lower 

 lip white and quadrifld ; disposed in verticillate racemes. I. lan- 

 ceolate-ovate, serrate, light green above, underneath brownish, 

 as is also the stem. East Indies, North Australia, Ac. A tall 

 herb or under-shrub. SYN. Ocimum scutellarioidet. (B. M. 1446.)

 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 Sin. in length, will root readily in well-drained po>

COLLIER. A common name of the Black Fly 

 (which gee). 



COLLINSIA (named after Zaccheus Collins, once 

 Vice-President of the Academy of Natural Sciences of 

 Philadelphia). OBD. Scrophularinece. 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 patting.
