leaves. Calyx-tube very short in the males, obconical in. the females, the 

 lobes narrow-lanceolate, obtuse. Corolla 2 to 2| lines long, the lobes nearly 

 equal but very oblique. Fruit very small, pubescent, globular, not seen 

 quite ripe, but evidently without the conical 2.valved summit of Lobelia. —

 the whole specimen represented is a male ; fig. 3 is a female, but the artist has inserted the 

 anthers from a male, thinking, no doubt, that those he found in the flower drawn were acci- 

 dentally not normally imperfect.

Calyx of Lobelia. Corolla-tube cylindrical, entire or rarely very shortly 

 slit on the upper side ; lobes 5, nearly equal, spreading, either quite hori- 

 zontal or very shortly and obliquely campanulate at the base. Stamens 

 inserted near the summit of the corolla-tube. Anthers of Lobelia, the upper 

 ones without terminal tufts. Pistil, capsule, and seeds of Zc?5e^/^.— Herbs, 

 with the habit of various species of Lobelia. Flowers axillary or in terminal 

 racemes or solitary, on long scapes or peduncles^ hermaphrodite in all the 



species known. 



A small genus, perhaps too artificially distinguished fi'om Lobelia, but the entire tube and 

 cpicorolline stamens are so exceptional in LoheHe<^ that there may be a convenience in keep- 

 ing it up. It is here eharacterized from the Australian species alone, which are all endemic 

 How far the extra- Australian species associated with it by Endlicher under the commoa 

 name of Laurentia, and distributed into various genera by Presl and Alph. De Candolle, 

 should or should not be considered as congeners, is a question requiring much further inves- 

 tigation. The precise form of the corolla, never perfectly regular, but more or less obliq'iei 

 can scarcely be made use of for generic distinction, for, as far as can be judged of from dried 

 specimens, it varies from species to species.
