H. fruticosa, Benth. Plant. Hartw., p- 78; Walp. Rep., vol. iii. p. 452. 
Leucocarrus fruticosus, Benth., 1. c. 350, et in DC. Prod., vol. x. p. 336. 
A very handsome rock plant, but not likely to be hardy ; 
found originally by Hartweg in Guatemala, and described by 
Bentham in 1839 as a new genus, which however he im- 
mediately after, but on insufficient grounds, merged into 
Leucocarpus. 
Nothing further was known of Hemichena till it was sent 
from Costa Rica by Endress, plants from whom flowered at 
Messrs. Veitchs’ establishment, July, 1873. _Osbert Salvin, 
F.R.S., an able ornithologist and assiduous collector of plants, 
next found it growing on the Volcan de Alitan in Guate- 
mala, at an elevation of 10,000 feet above the sea. Mr. Salvin 
sent seeds of it to England, which germinated and flowered 
at Kew, but the specimen here figured was from Mr. Veitch. 
Hemichena differs from Leucocarpus (one species of which, 
L. alatus, is figured in this work, Tab. 3067, as Mimulus 
perfoliatus), in the capsular fruits and anthers with parallel 
cells, as well as in the more deeply cleft calyx; in habit and 
foliage, the genera are remarkably alike. From Mimulus, with 
which Zeucocarpus was formerly confounded, both it and 
Hemichena differ in their inflorescence. 
Dzscr. A glandular pubescent shrub, three to five feet 
high ; branches terete, herbaceous, green. Leaves opposite, 
four to eight inches long, two to two anda half broad, oblong-
