1. L. GIBBOSA, Lab. Annual, erect, stems simple or with few flowering branches 

 when luxuriant, 6-18 inches high. Leaves mostly linear, but sometimes the, 

 lower ones broader with few obscure teeth. Flowers in a one-sided raceme, 

 deep-blue or purple tinged with pink. Ovary swollen above. Sepals short, 

 lanceolate. Corolla usually about \ inch long, the two upper , lobes small, 

 recurved, almost linear, the three lower ones more united, extended forwards, 

 oblong. Capsule \-\ inch long. Seeds very numerous, variable in size, and 

 more or less 3-angled. 



Very common. Found throughout Australia. Fl. Dec. -Feb. 



Von Mueller considers L. gibbosa, as adopted in Hook. " Fl. Tas." and 

 Benth. " Fl. Aust.," to include three distinct species : — 



L. siMPLiCAULis. Less robust than the type. Lobes of corolla all 

 acute. Fruit less-bulging above. Seeds larger than in the type, 

 ovate, triangular. 



L. BEOWNIANA. Leavcs linear. Corolla-lobes acute. Fruit much- 

 bulging above. Seeds very minute, almost dust-like. 



L. MiOEOSPEEMA. The typical form. Habit more robust and fleshy. 

 Leaves broader. Corolla-lobes obtuse. Capsule much swollen 

 above. Seeds very numerous, minute, and dust-like. 



2. L. EHOMBIFOLIA, De Vr. An annual, usually with jmany erect branches 

 arising froin the root-stock, 4 inches to 1 foot high. Leaves at the base broad 

 and deeply dentate, |-1 inch long ; stem-leaves narrower. Flowers few on each 

 stem, each on a long slender stalk. Ovary short. Sepals rather longer, 

 lanceolate. Corolla about | inch long, deep blue or purple, the upper lobes 

 small and recurved, the lower lobes extending forwards. Capsule swollen above. 

 Seeds small, numerous, and smooth. 



Near George's Bay. It also occurs in Victoria, South Australia, and West 

 Australia. Fl. spring. 



3. L. ANCEPS, D. C. A decumbent or sub-erect perennial. Stems angled, a 

 iew inches to 1 foot high. Leaves lanceolate to linear, |-2 inches long, obscurely
