36 V. MENISPEEMACE^. [Flou/i/mf. 



not excavated on- the sides, not with any internal process.- Seed reniform, 

 without albumen ; cotyledons thick and fleshy, scarcely separable ; radicle scarcely 

 distinct. — Flowers in short axillary branching panicles. 



Bentham remarks that this genus is distinguished from all. except the African Tru-lhlii, by 

 the remarkably valvate inner sepals. 



1. P. australis (Austradian), Benth. Fl. Amtr. i. 59. A climber, with a 

 soft pubescence like that of Pdicampylua, sometimes very copious, sometimes 

 quite disappearing from the upper surface of the leaves. Leaves from ovate to 

 oblong, obtuse or scarcely acute, the large ones 3 to 4in. long, rounded but mot 

 cordate at the base, at length rather coriaceous and shining above, reticulate 

 perininerved. Males cymes or single flowers in little axillary solitary or clustered 

 panicles, seldom above lin. long and softly pubescent ; inner sepals about 1 

 line long, the outer ones very minute. Female inflorescence probably more 

 simple. Drupes about 5 lines broad, glabrous, with a very thin endocarp. —

14. HUSEMANNIA, F. v. M. in Wing's So. Se. Kecord, iii. 187. 



(After Dr. Theodor Husemann, of Goettingen.) 



Sepals 9, in 3 series ; the 2 outer ones very minute, the 8 inner ones much 

 longer, ovate-roundish, valvate and slightly induplioate in the bud. Petals very 

 minute, flat, bilobed at the summit, much contracted at the base. Stamens of 

 male flowers 6, free except at the base ; filaments thickened upwards ; anthers 

 nearly globular but somewhat didymoi^, their cells opening by anterior almost 

 semicircular slits ; the connective narrow and not produced beyond the cells. 

 Ovaries of female flowers 6 ; stigma of each awl-shaped, recurved, undivided, 

 finally becoming nearly basal. Carpels on a conspicuous stipe, oblique-ovate, 

 somewhat impressed on both sides, rather acutely margined ; pericarp almost 

 coriaceous ; internal process erect, thin, flat, extending to somewhat beyond the 

 middle of the cavity. Seeds nearly cylindrical, conduplicate by horseshoe-like 

 curvature, no albumen, integument smooth ; cotyledons for the greater part of 

 their length turned dorsally towards the pericarp ; radicle extremely short. A 

 tall climber, with large, almost ovate, somewhat pointed and stiff leaves. 

 Flowers in spioate-panieulate clusters of very small, dark, silky-hairy flowers, 

 with short stamens and stipitate carpels. 



1. H. protensa (referring to its extending habit), F. v. M. A tall climber. 

 Leaves sometimes 15in. long and over 6in. in width, but often much 

 smaller, glabrous and shining, distantly penninerved, the closely reticulate veins 

 prominent on the under side. Petioles I to 3in. long, thickened and velvety 

 towards the top. Panicles about 15in. loijg, and thinly velvety. Flowers scarcelj 

 ^in. long, t"he inside of the sepals and both sifles of tbe. petals glabrous. Carpels 

 about fin. long, thinly brown-velvety, stipe about ^in. — F. v. M. in Wing's

Order VI. NYMPH^ACEiE. 



Sppals 3 to 5, petals 3 or more and stamens 6 or more, either. all free and 

 hypogynous, or the inner ones or all adnate at the base to the torus or ovary^ or 

 inserted on its summit. Anthers innate or adnate, the cells opening in longi- 

 tudinal slits. Gyncecium of 8 or more carpels, either free and distinet, or 

 immersed in the torus so as to iorm a several-celled ovary. Styles or stigmas
