produced above base into a very large spur ; limb small. Other 

 petals smaller ; anterior connivent, lateral rather erect. Stamens 5 ; 

 filaments very short, subperigynously inserted ; 2-4 inferior, shortly

 nearly of Viola, globose-3-gonal. Ovules very numerous ; style 

 clavate, anteriorly at apex stigmatiferous. Capsule coriaceous, large, 

 ovate, sub-3-agonal, ligneous, corticate ; valves 3, not elastic, semi- 

 niferous at middle ; seeds suborbiculate, piano-compressed ; testa 

 crustaceous, rugose, not winged ; albumen thin. — Scandent shrubs ; 

 leaves alternate, petiolate, ovate, often sharply serrate or serru- 

 late, glaberrimous, nitid; stipules deciduous; flowers 1 in terminal 

 racemes ; inferior solitary, in axils of upper leaves ; pedicels elon-

15. Sauvagesia L. — Flowers regular hermaphrodite ; receptacle 

 convex. Sepals 5, subequal, imbricated, finally very patent, fruc- 

 tiferous closed. Petals same in number, alternate, convolute, patent 

 at anthesis, deciduous. Stamens 5, fertile, alternipetalous, hypo- 

 gynous ; filaments free ; anthers linear, 2-locular, extrorsely or sub- 

 laterally rimose. Laminae petaloid 5 (staminodes ?) f alternating with 

 fertile stamens, and exterior to them, convolute, surrounded by fila- 

 ments, externally glanduliferous at apex (linear staminodes ?), 5-10, 

 oftener cc, in alternipetalous bundles. Germen free, 1-locular ; ovules 

 co , anatropous, ascendent, inserted on three parallel placentas ; style 

 simple, apex stigmatiferous, obtusely or scarcely dilated. Capsule 

 attended by persistent calyx and androceum, septicidal, 3-valved. 

 Seeds go, small ; testa crustaceous, usually scrobiculate ; albumen 

 fleshy ; embryo axile ; radicle rather terete, longer than cotjdedons. — 

 Glabrous herbs or undershrubs ; leaves alternate, rather rigid, entire 

 or serrulate, shortly petiolate or sometimes sessile ; stipules pecti-
