GENERIC CHARACTER. 



Oldenlandia (Linn.) Col. tubus subglobosus, dentes 4 per antliesin sub-approximati, in 

 fructu persistentes sinu latissimo separati distantes. Corolla breve tubulosa, limbo 4-fido, fauce 

 villosa. aut glabra. Stamina breve exserta, antheris ovatis aut orbicularis. Stigma indivisum, 

 aut bifidum. Capsula' subglobosa laciniis calycinis distantibus parvis coronata bilocularis 

 vertice loculicida rima dehiscens. Semina innumera minima placentae subglobosae adfixa et 

 quasi semi immersa. Stirpes Alsinoideae herbacese "rarissime fruticulosse. Folia opposita, 

 mediante stipula iis utrinque subadnexa. Pedunculi axillares aut terminales, uni-bi-aut 

 multiflori ssepius elongati graciles. — De Cand. Prod. vol. iv. p. 424. 



Tube of the calyx subglobose, teeth 4 somewhat approximating when in flower, remaining 

 on when in fruit, distantly separated by a very wide space. Corolla shortly tubulose, limb with 

 four divisions, throat villous, or smooth. Stamina shortly protruding, anthers ovate, or orbi- 

 culate. Stigma entire, or divided. Capsule subglobose crowned with the small distant divisions 

 of the calyx two-celled, bursting at the top with a loculicidal chink. Seeds innumerable, very 

 small, adfixed to subglobose placentas and as if half immersed. Plants resembling chickweed, 

 herbaceous, very rarely shrubby. Leaves opposite, having the stipules somewhat joined to them 

 on both sides in the middle. Peduncles axillary, or terminal, one, two, or many-flowered, 

 oftentimes slenderly elongated.
