A curious genus of Conipositce, raised from seeds received
from M. de Fischer, director of the Imperial Botanic Garden
at St. Petersburg, and recorded in the appendix to the catalogue
of seeds of that Garden for 1835. It is a native of the
Russian colony of Ross in New California, the nearly related
genus Callichroa already figured at TAB. 373, having been
obtained from the same quarter. ¡. r;
The present genus is closely allied to M a d am of De Candolle,
but differs in its perfectly glabrous rhachis, and in
the whole of the florets being fertile, and the rays nearly
entire. . i n j •
Our drawing was taken from a plant whicli flowered in
the collection of our worthy friend Mr. Jaiison, at Stoke
Newington in the spring of the present year.
The genus was dedicated by Fischer and Meyer to the
late Professor de Baer of the University of Dorpat, and distinguished
for his labours in comparative anatomy. The
specific name alludes to the anthers being of a yellow colour,
and not black, as is the case in many genera of the same
group.
