Some hitherto unknown Australian Plants. 61 



An annual herb, generally less than one foot high. 

 Largest leaves \ inch long. Bracts measuring in length 

 about one line, broader than the bracteoles. Corolla purple, 

 hardly half an inch long; the upper lip nearly semiorbicular, 

 slightly emarginate, half as long as the lower one ; middle 

 lobe of the latter round-cordate, lateral ones orbicidar-ovate. 

 Sterile stamens white, enclosed. Anthers one-celled, but 

 perhaps only by the confluence of divaricate lobes, but cer- 

 tainly not so clearly two-celled as in Vandellia scapigera, 

 which bears to V. clausa the greatest resemblance, still is 

 furnished with 4 fertile stamens, as an examination of speci- 

 mens collected at Macadam Range has proved; two of the 

 filaments in Vandellia scapigera are furnished at the base 

 with a short filiform glandulous appendage. Its corolla is 

 white. The anthers are coherent in pairs. Lamels of the 

 stigma sometimes unequal. Capsule 3-4 lines long, about 

 three times longer than the calyx. 



Vandellia lobelioides. 



(Sect. Boimaya.) 



Glabrous; stem simple, erect, provided with leaves only at 

 the base, but towards the middle with one or two distant 

 pair of bracts ; leaves broad-ovate, repand or quite 

 entire, the lowest the smallest ; racemes few-flowered, 

 the terminal one solitary, in addition to which some- 

 times a lateral one, shortened to a corymb and occa- 

 sionally reduced to a single flower ; bracteoles all oppo- 

 site, linear-subulate, many times shorter than the 

 pedicels; the latter four to six times longer than the 

 calyx ; tube of the coralla upwards widened, twice as 

 long as the calyx ; sterile stamens totally adnate, form- 

 ing two very prominent carinas ; faux open ; fertile 

 stamens with coherent one-celled anthers; capsule ovate, 

 shorter than the style ; seeds brown-yellow, angular, 

 transversely wrinkled. 

 A companion of Vandellia clausa, to which it stands in 

 close affinity. 



An annual herb, with the habit of a Lobelia, from a finger 

 to a span long. Bracts narrow-lanceolate, l-\\ line long, 

 never missing, broader than the bracteoles. Segments of the 

 calyx linear-subulate. Corolla nearly half an inch long, blue, 

 rarely pink or white ; its upper-lip semiovate, with two short 

 and acute teeth, or emarginate, plicate, often whitish, three
