GENUS XX. 
CALLICHROA, Fisch. et Meyer. THE CALLICHROA. 
Lin. Si,st. SYNGENESIA SUPERFLUA. 
Generic Character. —Head lieterogamous. Flowers of the ray 
female, ligulate, in two series ; those of the disk tubular, hermaphro¬ 
dite. Involucrum double, of mauy nearly equal scales. Receptacle 
depressed, fringed, or furnished with two or three roivs of paleai 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 setaceous, denticulated, in one series. 
CALLICHROA PLATYGLOSSA, Fisch. et Mey. THE BIIOAD-RAYEU CALLICHROA. 
Engravings.— Swt. Brit. Flow. Gard. 2nd ser., t. 373; and our 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 largo 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 front 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. 156), 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 he 
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 lieterogamous, radiate. Scales of in- female, ligulate, in one series. Fruit fusiform, compressed, somewhat 
volucrum about ten, equal, flat, and in two series. Receptacle conical, tetragonal, obtuse, terminated by a small areola, 
naked. Flowers of the disk hermaphrodite, tubular; those of the ray, 
BAERIA CHRYSOSTOMA, Fisch. et Mey. THE GOLDEN-ANTHERED BAERIA. 
Engravings. —Swt. Brit. Flow. Gai'd. 2nd ser., t. 395; and our fig. 13, in Plate 31. 
Specific 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. Though there are many botanical distinctions, the principal 
popular differences 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.
