42 NATURAL HISTORY OF PLANTS. 



rarely 12-16, the oppositipetalous oftener much smaller ; anthers 

 ovoid or ohlong, sometimes linear, 1- porous at more or less tubular 

 apex,^ connective more or less produced inwardly at base beyond the 

 insertion of the filament, curved and there generally dilated, entire or 

 more rarely 2-lobed. Germen either free, or more or less deeply 

 adnate within receptacle, either 8-5-celled (Tremhleya),^ or 3-8-celled 

 (Eumicrolicia^ Lavoisiera) ; style slender, often declinate or incurved, 

 sometimes thickened towards apex (Rhynchanthera) ; at top stigmatose 

 punctiform. Capsule 4-8-valved ; seeds straight or more or less 

 curved, sometimes foveolate. — • Shrubs, shrublets, or rarely herbs, 

 glabrous or pilose ; or with glandular pilose, sometimes {Lasiotrem- 

 hleya ^) densely hoary indumentum ; leaves often small, imbricate ; 

 flowers* axillary or terminal, solitary or in compound cymiferous 

 racemes. (Trop. South America J) 



10 ? Cetradenia G. Don.^ — Flowers nearly of MicroUcia, 4- 

 merous ; sepals 4, shorter than receptacle. Stamens 8, unequal ; 

 anthers oblong, obtuse, erostrate ; connective produced at base in- 

 curved and compressed, clavate at bottom and there truncate or 2- 

 lobed. Germen, &c., of MicroliciaJ — Herbs, sometimes subshrubby ; 

 branches 4-alate or 4-gonal ; leaves of each pair ^ very dissimilar ; 

 one very small (or sometimes 0) ; the other larger unequally lanceo- 

 late ; flowers ^ in corymbiform cymes. (South-west. North America?^) 



11 ? Chsetostoma DC.^' — Flowers nearly of Mcrofe'a, 5-merous; 

 receptacle tubular-campanulate coriaceous sparsely setose. Sepals 5,
