38 NATURAL HISTORY OF PLANTS. 



(sterile in female flower), either free {Tinospora, Colombo), or more or 

 less strongly 1-adelphous {Euchasmanthera, Jateorhiza) ; anthers 

 extrorse, lateral or subterminal; cells 2, rimose, more or less 

 confluent at apex. Carpels 3 (of Cocculus), styles narrow or dilated, 

 divided. Drupes destitute of prickles or aculeate, smoother within, 

 marked by cicatrix of style a little under apex ; putamen concave 

 within; process hemispherical or semi-ovoid, intruded, leaving an 

 empty false-cell. Seed meniscoid, convex outwardly; albumen 

 of same shape, fleshy, more or less ruminated or subcontinuous ; 

 embryo incurved; radicle superior cylindrical; cotyledons mem- 

 branous, divaricating laterally on each side between the lamina? of 

 albumen. — Stems climbing, smooth or pilose-aculeate; leaves 

 alternate cordate at base, entire or palmatilobate, rarely hetero- 

 morphous ; flowers in simple or branched racemes ; male inflores- 

 cence more branched {Asia, Australia, Tropical Africa). See p. 11. 



19. Calycocarpum Nutt. — Sepals 6, subequal, thin, in 2 series. 

 " Petals 6, somewhat flattened." Stamens 6-10 (6, sterile in female 

 flower), free ; anthers basifixed introrse ; cells vertical, longitudinally 

 rimose. Carpels 3 ; styles lacerated ; apex stigmatose. Drupes un- 

 equally ovoid, rather flat within ; scar of style subterminal ; putamen 

 concave within ; process intruded hemispherical. Seed meniscoid, 

 markedly concave within ; albumen thin ; embryo of Chasmanthera. — 

 Stems climbing, leaves palmatilobate, cordate at base ; flowers in 

 narrow composite racemes {North America). See p. 13. 



20. Tinomiscium Miers. — Sepals 6-9 ; outer 3 smaller, bract- 

 like. Petals 6, a little shorter than sepals, suborbicular erect. 

 Stamens 6, free, attenuate at base, clavate and expanded behind at 

 subincurved apex, subcarinate inside ; anther-cells lateral at apex. 

 Female flower. . .? "Drupes ovate-oblong, very compressed; scar 

 of style terminal ; putamen with a flat surface ; lamina intruded, 

 projecting a little." Seed. . . ? — Leaves often large, coriaceous, 

 3-5-nerved at base ; flowers in lengthened simple or sparsely 

 branched racemes {Tropical Asia). See p. 13. 



21. Odontocarya Miers. — Flowers almost of Chasmanthera; 3 

 inner sepals thinner. Petals 6 ; shorter, somewhat flattened.
