326 NATURAL HISTORY OF PLANTS. 



The same characteristics occur in Houstonia,^ a small herb of warm 

 and temperate America, with flowers often dimorphous, axillary or in 

 biparous cymes, mostly tetramerous, and the loculicidal capsule 

 encloses seeds more or less peltate as in some other sections of this 

 genus. The ovary and septicidal fruit are also partly superior in 

 Leptoscela,^ a BraziUan herb having the characters of vegetation and 

 inflorescence of HeMstocarpa, with the habit of some Raellias, and 

 whose seeds are longer than wide. 



The corolla not unfreq'uently becomes tubular, clavjform or pointed 

 in the bud in certain Oldenlandias of both worlds. The character is 

 especially marked in most of those of which have been made the 

 genera Amtis,^ Teinosolen^ and Kaclua.^ The latter, from the 

 Sandwich islands, the type of which is Hedijotis data, has a tetra- 

 merous flower with long tubular corolla and a coriaceous or slightly 

 fleshy capsule, loculicidal at the summit, with angular or winged 

 seeds, attached at the surface or in depressions of thickened placentas. 

 The flowers are in terminal axillary or lateral cymes. Anutis is 

 American, Asiatic or rarely Australian ; it has a tubular corolla, if 

 claviform in the bud, 4-lobed ; an ovary generally bilocular,^ locuhcidal 

 and bivalved; seeds compressed or slightly winged. They are 

 herbaceous or subshrubby plants, with axillary and terminal, often 

 corymbiform or capituliform cymes. Teinosolen'' also has an elongate 

 corolla with five valvate lobes. The capsular fruit is crustaceous and 

 septicidal. They are glabrous ramose Bolivian shrubs with small 

 opposite or subfasciculate coriaceous leaves with indistinct nervures, 

 and few or sohtary terminal flowers. 



Thus defined,^ the great genus Oldenlandia comprises about two
