Solanum stelligerum J.E. 8m. var. procumbens var. nov. 
Planta deeumbens, caulibus radicantibus, ramis ascendentibus 20-30 
cm. alt., foliis late ovatis, ellipticis vel, fere oblongis. 
Moreton District : Lamington National Park, alt. ca. 1,000 m., in 
rain-forest, C. T. White 11889 (type: flowers), 27-11-1942 (prostrate 
Solanum, creeping stems rooting freely and here and there sending up 
shoots 20-30 cm. high, flowers lilac) ; Numinbah, C. T. White 10232 
(flowers), 10-4-1935 (procumbent Solanum common on floor of rain- 
forest, rooting here and there at the nodes) ; Currumbin, C. T. White 
sine No. (flowers), Sept. 1912 (quite prostrate, almost carpet-like, occa- : 
sionally half-climbing), head of Little Nerang River, C. T. White sine No. 
(flowers), Jan. 1916 (a Solanum creeping near the ground) . 
Apart from its prostrate habit the present variety can generally be 
told at sight from the normal form by its broad short leaves. After 
considerable time spent on, an examination of all our material, however, j 
I consider it only worthy of varietal rank, especially as a prostrate 
variety also occurs of the closely allied S. discolor R. Br. 
Family Scrophulariaceae.
