XXII. FISCHERIA (named after F. E. L. Fischer, M.D. 
Director of the Botanic Garden at St. Petersburgh.) D. C. 
cat. hort. monsp. 1813. p. 112. 
Lin. syst. Pentdndria, Digynia. Corolla rotate; segments 
undulately curled. Stamineous corona fleshy, truncate, but not 
otherwise lobed, girded at the base by a nectariferous ring. 
Anthers simple at the apex, hooked, replicate inside ; pollen 
masses inserted by the middle of the side, lying upon the stigma. 
Stigma pentagonal.  Follicles two.—A climbing, evergreen 
shrub. Branches long, terete. Leaves opposite, cordate at the 
base, oval-oblong, acute, petiolate. Peduncles interpetiolar, 
bearing simple umbels of pedicellate flowers. This appears 
to be intermediate between Microstémma and Hoya; but it differs 
from them, and all the other allied genera, in the corona being 
entire. 
1 F.sca'wpzews (D. C. I. c. t. 67. ined.) h.,,. S. Native, 
probably of South America. Branches downy. Flowers yel- 
lowish green. Very like Cynánchum crispiflórum, Swartz ; 
but differs from it, in the calycine segments being shorter, 
spreading, not reflexed ; in the corolla being rotate, not with a 
pentagonal tube ; and particularly in the corona and genitals.
