Jacobinia (probably a personal name). Including Cyrtanthera, Libonia, Sericographis, Sericobonia. Acanthaceae. Plants cultivated under glass for their narrow- tubular red, orange or yellow flowers.

Glabrous herbs, or sometimes shrubs: lvs. opposite and entire: fls. variously disposed, sometimes solitary, sometimes fascicled or spicate; calyx deeply 5-parted, with linear or awl-shaped segms.; corolla more or less 2-lipped, 1 lip 2-lobed and the other 3-lobed; stamens 2; staminodia represented by 2 hairy elevations on the corolla-tube; disk ring-like or cupulate; pistil ripening into an oblong or ovate caps., the style filiform.祐pecies 20-40, depending in part on the definition of the genus, from Mex. to Bolivia and Brazil.

Jacobinias, in common with other acanthads, are much confused as to species. A closely allied genus is Justicia, which, among other characters, is distinguished by having spurs or appendages at the base of the antherlobes, whereas Jacobinia has no such appendages. Most of the garden plants called Justicias are Jacobinias. Other allied genera are Aphelandra, Dianthera, Adhatoda, Thyreacanthus, Eranthemum, Barleria, Daedalscanthus.

In their native places, jacobinias are mostly sub- shrubs, but they are usually treated as herbs under cultivation. They are showy greenhouse or conservatory subjects. When well grown they are attractive plants, but they soon become weedy under neglect. They propagate very readily from cuttings, after the manner of fuchsias, and the most satisfactory plants are usually those that are allowed to bloom but once. Most of them thrive well under conditions suited to begonias.


J. lindenii, Nichols, (Justicia lindenii, Houll.), is a Mexican subshrub, with long-ovate opposite decussate lvs., and a dense fascicled head of orange-yellow fls.: divisions of calyx linear; corolla long-tubular, 2 in. or more; 2 stamens attached in lower part of corolla. Does not appear to be in the trade. R.H. 1870:250.
