54 MB. G. BENTHAM ON TILIACE^E. 



approaching near to some Sterculiacece ; 2. Grewiece, with free 

 sepals, short anthers opening longitudinally, and the petals foveo- 

 late at the base, and inserted round the base of a raised torus, 

 bearing the stamens on the top ; 3. Tiliece, with the sepals and 

 anthers of Gremieas, or the anthers rarely elongated, but still ver- 

 satile, and the petals never foveolate at the base and inserted close 

 round the stamens, which cover the small or flattened, but never 

 raised torus ; 4. Apeibeas with free sepals, but remarkable for 

 their erect linear anthers with the connective more or less pro- 

 longed into a membrane beyond the cells ; their dehiscence is, 

 however, by longitudinal slits, as in other Holopetalce. In the 

 Heteropetala we have two tribes : 5, Proclciece, comprising three 

 somewhat anomalous genera, with small globular or ovoid anthers 

 opening longitudinally ; and 6, JElceocarpece, with erect anthers 

 usually linear, often prolonged into a point, and opening from the 

 apex downwards in confluent pores or short slits, giving them 

 often a 2-valved appearance. These JElceocarpece are again divi- 

 sible into two subtribes — Sloanece, with a broad, flat or convex disk 

 entirely covered with stamens; and Euelceocarpece, with the stamens 

 on the top of a raised disk, round the base of which the petals are 

 inserted as in Grewiece. 



The following synopsis will more clearly show the proposed 

 distribution of the Tiliaceous genera : — 



Subordo I. Hoiopetal^j. Petala glabra, colorata, tenuia, basi 

 contracta v. unguiculata, integra v. rarissime emarginata, 

 decidua. 



Tribus 1. Bbowklowie^:. Sepala in calycem campanulatum, 

 3-5-fidum coalita. Antherce subglobossa v. didymae, loculis 

 demum confluentibus. 



* Stamina 5 interiora ananthera (staminodid) . 

 Genera: — 1. Pentace, Hassle.; 2. Brownlowia, Boxb.; 3. Di- 

 plodiseus, Twrczan; 4. Pityranthe, Thw. 



** Stamina omnia antherifera. 

 Genera:— 5. Christiania,_DC.; 6. Berrya, itorJ. (Hexagonotheca, 

 Turczan.). 



Tribus 2. Gbewieje. Sepala distincta. Petala basi foveolata, 

 circa basin tori elevati apice staminiferi inserta. Anthera 

 breves, loculis parallelis, distinctis.
