GENUS XX. 
CALLICHROA, Fisch. et Meyer. THE CALLICHROA. 
Lin. Spst. SYNGENESIA SUPERFLUA. 
Grneric Charactrr. — Head heterogamous. Flowers of tlie ray 
female, ligulate, in two series ; those of the disk tuhular, hermapliro- 
dite. InvoUicrum double, of many nearly equal scales. Receptacle 
depressed, fringed, or furnished with two or three rows of paleae along 
the edge. Achenia somewhat fusiform : those of the ray glabrous, and 
a little compressed ; those of the disk elongated, and somewhat trun- 
cate. Pappi set.aceous, denticulated, in one scries. 
1.— CALLICHROA PLATYGLOSSA, Fisch. et Mey. THE BROAD-RAYED CALLICHROA. 
Engravings.— Swt. Brit. Flow. Gard. 2nd ser., t. 373; and out fig. 15, in Plate 31. 
Specific Character — Leaves alternate, sessile. Heads solitary, pedunculate ; ray-flowers cuneate. 
Description, &c. — A very showy plant growing about a foot high, with slender branching stems, bearing a 
profusion of large golden-yellow flowers, with dark purple anthers to the flowers of the disk. The brilliant 
colour of these flowers gives the name to the genus ; as Callichroa is derived from two Greek words signifying 
beautiful colour. The flowers do not look quite so well when gathered as when in the bed, from the stems and 
leaves being covered with rather long hairs ; but this is only a trifling objection. The species is a native of the 
Russian colony of Ross in New California, whence it was first sent to the St. Petersburg Botanic Garden in 1835 ; 
but it was not introduced into England till 1837. It is quite hardy, and may be treated like the other Californian 
annuals (see p. 1.50), or sown in the open border in March or April. It is well adapted for forming a yellow 
bed in a geometrical flower garden. Though so recently introduced, it seeds so freely that it may already be 
purchased in most of the seed-shops. As it has a descending root, care should be taken in transplanting to keep 
as much earth as possible about the fibres, as when injured they are not so readily renewed as those of spreading- 
rooted plants. 
GENUS XXI. 
BAERIA, Fisch. et Mey. THE BAERIA. 
Lin. Syst. SYNGENESIA SUPERFLUA. 
Generic Character. — Head heterogamous, radiate. Scales of in- 
volucrum about ten, equal, fl;it, and in two seiies. Receptacle conical, 
DKked. Flowers of the disk hermaphrodite, tubular; tliose of the ray, 
female, ligulate, in one series. Fruit fusiform, compressed, somewhat 
tetragonal, obtuse, terminated by a small areola. 
BAERIA CHRYSOSTOMA, Fisch et Mey. THE GOLDEN-ANTHERED BAERIA. 
Engravings. — Swt. Brit. Flow. Gard. 2nd scr., t. 395; and om fig. 13, in Plate 31. 
SpEciric Character. — Plant slender, erect, branched, rather hairy. Leaves opposite, sessile, linear, quite entire. Heads terminal, solitary. 
Description, &c. — This genus is nearly allied to that of Callichroa ; and it is a native of the same place, 
having been sent to Europe at the same time. Tliough there are many botanical distinctions, the principal 
popular difibrences between the genera consist in the shape of the rays, which are pointed in Baeria, and wedge- 
shaped in Callichroa, and in the anthers of Baeria being all yellow. The genus was named in honour of Professor 
De Baer of the University of Dorpat. Though it was introduced at the same time as the Callichroa, yet from 
not seeding so freely, it is not included in any of the catalogues of the seed-shops, and we do not know where it 
is to be procured.
