COLAX HARRISONIZ:. A synonym of Bi- 
frenaria Harrisoniz (which see). 
COLCHICUM. About thirty species, natives of 
Europe, West and Central Asia, and North Africa, are here 
included. To those described on p. 359, Vol. I., the fol- 
lowing should now be added:

who assisted Hooker in the investigation of the botany of 
New Zealand). Orp. Campanulacee. A monotypic genus. 
The species is a glabrous, erect herb, suffrutescent at 
base. It will thrive in sandy loam, and would probably 
succeed in the open air, in a warm, sheltered place. 
Propagated by seeds or by cuttings. 
Cc. a Aen wed (Physalis-like). /. very pale bluish, 14in. long, 
bilabiate, the upper lip divided into two linear lobes ; stamens

globose berry, crowned by the linear, green calyx teeth. J. alter- 
nate, petiolate, elliptic-ovate, acute, doubly serrated, 4in. to 
6in. long. h. 2ft. to ft. New Zealand, 1886. (B. M. 6864.)

acute, cordate-sagittate at base, highly glabrous, green, the 
sinus large, triangular; primary veins three or four on both 
sides, produced on the lower surface, brown; petioles elongated, 
terete, sheathing at base, coppery-brown. Caudex short and 
thick. New Guinea, 1886. (I. H. 1886, 601.) 
COMPARETTIA. This genus embraces five species, 
natives of the Andes of South America. Sepals erecto- 
patent, the dorsal one free, the lateral ones connate, 
produced at base into a long, slender spur which is free of 
the petals; lip continuous with the base of the column, 
produced at base into two long, linear spurs, the lateral 
lobes rather broad, erect, the middle one spreading, very 
broad. To the species described on p. 366, Vol. I., the 
following should now be added: 
C. speciosa (showy). /l. large and numerous; sepals and petals 
light orange, with a cinnabar glow; lip cinnabar, orange at base, 
the front lobe sub-quadrate and emarginate, about 1jin. wide,

auricles; spur minutely pilose, upwards of ljin. long; racemes 
loose. Ecuador. A beautiful species. 
CORDYLINE. The species are found in the East 
Indies, the Malayan Archipelago, Australia, New Zealand,

red in the adult state; when young, brilliant red, flaked with 
brownish. 1886. A beautiful, garden variety.

youngest ones pale green, with broad bands and margins of 
creamy-white, faintly tinged rose; older ones of a deeper green,

useful for decorative purposes, as it bears changes of temperature 
better than many other kinds.

acuminate, arching. Madagascar, 1884. A distinct form, of 
graceful habit.

Of the dozen species embraced in this genus six are North 
American, and the rest inhabit West Asia or the Hima- 
layas. ‘To those described on p. 383, Vol. I., the following

with a pale brown patch on the dorsal petal, lin. long ; racemes 
lin. to 5in. long, many-towered. March. J. tripinnatisect ; 
leaflets very variable, oblong, obovate, or cuneate, variously 
cut. h. 1ft. to 1ift. China and Japan, 1884. (B. M. 6826.) Syn. 
C. aurea speciosa (R. G. 1861, 343.)

added : 
C. levigatus aureo-marginatus (golden-margined). J. broadly 
bordered with golden-yellow. 1886. An ornamental variety, of 
compact habit. 
CORYPHA. Of this genus about half-a-dozen species, 
natives of tropical Asia and the Malayan Archipelago, have 
been enumerated. Flowers small, hermaphrodite; spadix 
solitary, erect, paniculately much branched ; spathes many, 
tubular, sheathing the peduncle and branches. ‘To the 
species described on p. 386, Vol. I., the following should 
now be added: 
C. decora (decorative). /. fan-shaped, divided almost to the base 
into linear segments 4in. broad; petioles armed with hooked 
prickles. 1887. An ornamental Palm. In all probability this 
does not belong to the genus Corypha.
