•118 xcn. scrophulariace.e (hemsley and skan). [Strigina. 



Description wholly from Engler. The plant, judging from Engler's figure, has 

 the appearance of a diminutive species of Striga, from which genus it differs in 

 having only two perfect stamens, which are inserted in the mouth of the tube, at the 

 base of the upper lobe or lip of the corolla.

Calyx campanulate, 5-ficl ; teeth or lobes usually acuminate. 

 Corolla-tube slender, elongated, straight or incurved, sometimes 

 gibbous near the apex ; limb broad, spreading, more or less distinctly 

 2-lipped ; lobes 5, obovate or suborbicular, the upper 2 inside and 

 usually more connate than the lower. Stamens 4, didynamous, in- 

 cluded in the tube; anthers 1 -celled, vertical, dorsifixed ; connective 

 very shortly acuminate at the apex. Style thickened or clavate above. 

 Ovules numerous in each cell. Capsule ovate or suborbicular, com- 

 pressed contrary to the septum, nearly always oblique and produced at 

 the apex into an incurved rarely straight beak (obtuse or retuse in 

 R. cameroniana), dehiscing loculicidally, often by the upper suture 

 only. Seeds numerous, \ to nearly \ lin. long, obovoid, ellipsoid, 

 oblong or subclavate, often truncate at both ends ; testa reticulate or 

 longitudinally striate, smooth or tuberculate. — Herbs or undershrubs, 

 probably sometimes parasitic, often drying black, erect or decumbent, 

 more or less branched, glabrous or hairy. Leaves opposite below, 

 alternate above, often narrow, entire, toothed or pinnatisect. Flowers 

 in the axils of the upper leaves, pedicellate or rarely subsessile ; pedicels 

 usually minutely bibracteolate. Corolla rather large, white, purple, 

 pink or red. — Macrosiphon, Hochst. in Flora, 1841, 373.
