IV. GAUDICHAUDIE^. 



44. Schwannia Endl. — Flowers hermaphrodite ; calyx rloeply 

 5-fid or G-partite ; glandviles oftener 8. Petals 5, iinguiciilato fim- 

 briate, imbricate. Stamens 6, fertile, unequal ; filaments glabrous, 

 l-adelj)hons at base or in part free ; anthers introrse pilose. Carpels 

 of gynteceum 3 ; germens free ; style gynobasic 1 (or sometimes 

 2, .8), at apex stigmatose capitellato; ovule in cells 1, descendent, 

 incompletely aiiatropous. Samarœ 1-3, each subtending a filiform 

 finally separable column; hilum of curved seed ventral; cotyledons 

 of exalbuminous embryo oblong ; radicle rostrate. — Scandent shrubs ; 

 leaves opposite entire eglandulnse petiolate ; flowers in cymules 

 often 4-florous and collected in terminal compound-ramose racemes ; 

 pedicels 2-bracteolate. (Tropical Brazil.) See p. 441. 



45 ? Janusia A. Juss.^— Flowers 2-morphous; the normal nearly 

 of Schwannia; j^etals eubentire. Stamens 6, either all fertile, or 

 sometimes more sterile ; anthers glabrous.^ Samaraj 1-3 and 

 other characters of Schwannia. Flowers abnormal in eglandulose 

 calyx. Petals oftener rudimentary. Carpels 2 ; styles rudimentary 

 or 0. — Shrubs or undershrubs, generally scandent ; leaves opposite 

 entire ; flowers ^ in axillary and terminal, often o, 4-flowered (spu- 

 rious) umbels; pedicels 2-bracteolate, [Extra-tropical Brazil., tuarm 

 northern and tvestcrn America.'^') 



4(3. Camarea A. S. H.^ — Flowers 2-morphous ; the normal nearly 

 of Janusia ; stamens 6, of which 5 are alternipetalous ; 4 fertile ; 

 2 sterile ; filaments glabrous, 2-adelphous (of which 3 are highly con- 

 nate, but 3 only at the base) ; anthers of fertile flowers short, 2-locu- 

 lar ; of the sterile deformed to a glandulose subcapitate-contortuplicate 

 mass. Carpels 2-4 free; style gynobasic (of >S'c/;?y«?im'a). Nuts 1-4, 

 furnished with a short dorsal wing or oftener seriately echinate, mu- 

 ricate or lappulaceous. Abnormal flowers apetalous ; calyx eglan- 

 dulose; anther rudimentary 1. Carpels 2 (of Janusia). — Shrubs
