IV. GAUDICHAUDIE.^. 



44. Schwannia Endl. — Flowers hermaplirodite ; calyx deeply 

 5 -fid or r) -partite; glandules often er 8. Petals 5, iinguicnlate fim- 

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

 1-adelphous at base or in part free ; anthers introrse pilose. Carpels 

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

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

 incompletely anatropous. Samara) 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 eglandulose petiolate ; flowers in cymules 

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

 pedicels 2-bracteolate. {Tropkal Brazil.) See p. 441. 



45 ? Jauusia A Juss.i —Flowers 2-morphous; the normal nearly 

 of Sclmannia ; petals subentire. Stamens 6, either all fertile, or 

 sometimes more sterile; anthers glabrous.- Samaras 1-3 and 

 other characters of Sclmannia. Flowers abnormal in eglandulose 

 calyx. Petals oftener rudimentary. Carpels 2 ; styles rudimentary 

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

 entire ; flowers ^ in axillary and terminal, often 3, 4-flowered (spu- 

 rious) umbels; pedicels 2-bracteolate. {Extra-trojncal Brazil, zvarm 

 northern and western America*) 



46. Camarea A. S. 11.^ — Flowers 2-morphous ; the normal nearly 

 of Jannsia ; 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 Sclmannia). Nuts 1-4, 

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

 ricate or lappulaceous. Abnormal flowers apetalous ; calyx eglan- 

 dulose; anther rudimentary i. Carpels 2 (of Janusia). — Shi-ubs
