 411, allknowQ only from Presl's diagnoses, belong probably to this species, which connects 

 the genus with true LoheliaSy and has the habit oi L. pratioides and Pralia pubertila, but 

 the insertion of the stamens near the orifice of the corolla-tube induces its reference to 

 Isotoma. 



WAHLENBERGIA 



Calyx 5- or rarely 4-lobe(l or in abnormal flowers 6- or 7-lobetl. Corolla 

 regular, campanulate or more or less tubular at the base, with as many val- 

 vate lobes as calyx-lobes. Stamens free. Ovary 3- to 5-celled or rarely 2- 

 celled. Style with as many stigmatic lobes as ovary-cells. Capsule opening 

 at the top loculicidally within the calyx-teeth, in as many valves as cells.— 

 Herbs. Leaves alternate or very rarely opposite or whorled. Peduncles 

 terminal or in the upper axils, often forming loose, terminal, dichotomous, 

 leafy panicles. Flowers usually blue. 



A considerable genus, dispersed over various parts of tlie world, most abundant in Southern 

 -^^nca. The two Australian species are both in New Zealand, and one appears to be the 

 same as a common one in tropical Asia. 



Stems leafy, simple or branched. Leaves sometimes' crowded but not 

 rosulale , . , 1. W. gracilis,
