CONDAMINEA. 



little longer than the calyx, a dilated throat, and a 5-parted 

 limb. Stamens inserted above the middle of the tube, or near 

 the throat ; anthers oblong-linear, bifid at the base, length of 

 corolla. Stigma 2-lobed. Capsule turbinate, truncate, opening 

 in the middle of the cells. Seeds numerous, very small, wedge- 

 shaped American shrubs, with 2 -parted, acuminate stipules, 



and terminal many-flowered corymbs. 



866. C. corymbosa DC. prodr. iv. 402. Macrocnemum 

 corymbosum FL peruv. ii. 48. 1. 189. HBK. iii. 399. Hills 

 and ravines of the Peruvian Andes; mountains of Huanuco ; 

 near Maraquita and Santa Anna in New Granada. 



Leaves ovate-oblong, acuminate, cordate, sessile, plaited, coriaceous. 

 Corymbs large, brachiate, trichotomous. Corolla purple externally, 

 with the throat and filaments naked. Teeth of the calyx broad, short 

 and blunt. Bark febrifugal. The Bark gatherers of Peru are said by 

 Ruiz and Pavon to use this plant for adulterating the samples of Cin- 

 chona. Its bark is only slightly bitter, and may be easily recognised 

 by its being white inside, rather bitter and viscid. 



OPHIORHIZA. 



Tube of calyx short, turbinate, with a permanent 5-cleft limb. 

 Corolla tubular, funnel-shaped, hairy inside, with 5 ovate lobes. 

 Stamens enclosed in the tube. Style filiform, surrounded at the 

 base by a cup ; stigma 2-lobed, shorter than the corolla. Cap- 

 sule broad, compressed, 2-lobed, crowned by the calyx. Seeds 

 numerous, small, hexagonal.

 prodr. iv. 415. Mungo K&mpf. amoen. 573 and 577. Java, 

 Ceylon, Sumatra. 



Stem suffruticose. Leaves stalked, oblong, entire, pointed, very thin, 

 4-6 inches long; petioles short, downy; stipules slight, membranous. 

 Corymbs terminal, many-flowered. Tube of the corolla short, with 

 the lobes oblong, and pointed. Cup of the style 2-lipped, thick, fleshy. 

 Filaments very short, inserted at the base of the tube. Capsule in- 

 versely reniform, compressed, with 5 ribs proceeding from the lobes of 

 the calyx. The parts are so intensely bitter that the plant is called 

 by the Malays, " Earth gall ; " according to Kaempfer the taste re- 

 sembles Gentian, but is more penetrating and less unpleasant. It has 

 the reputation of being a most powerful alexipharmic ; but this re- 

 quires confirmation. 



OLDENLANDIA. 



Calyx with a globose tube. Limb 4-toothed, permanent, the 

 lobes very distant in the fruit. Corolla short, with a 4-cleft 

 limb, and a villous or glabrous throat. Stamens a little exserted ; 

 anthers ovate or orbicular. Stigma undivided or bifid. Capsule 

 nearly globose, crowned by the small, distant lobes of the calyx, 

 dehiscing at the vertex by a loculicidal chink. Seeds nume-
