Lactuca scariola, L. "Prickly Lettuce." (Corapositae). 



Benalla. Victoria. W. B. Tiernan. January, 1913; Rutherglen, 

 Victoria, G. H. Adcock, January, 191-3. 



A native of Europe and Central Asia, not previously recorded 

 for Victoria as a naturalised alien. It is an annual or biennial 

 weed of no economic value, and apt to be spread readily by it* 

 flat seed-like fruits, provided with a parachute mechanism of 

 pappus hairs. 



LiMOSELLA AQUATICA, L. (Scrophulariaceae). 

 This little cosmopolitan plant varies somewhat in different parts 

 of the world. The Australian specimens usually have more or les* 

 linear leaves, as shown in Figure I. Occasionally, however, speci- 

 mens occur with oblong or almost spatliulate leaves (J. P. Eckert. 

 Murtoa. Victoria, 1912). and this is the common form in Europe 

 and Asia. 



LiNARiA Pelisseriana, L. (Scrophulariaceae). " Pelisser's 

 Toad Flax." 



Guy's Forest and various localities along tlie Upper Murray, and 

 Corryong and Cudgewa Valleys. Victoria. -A. J. Ewart, 6/11/1912. 



LiNARiA VULGARIS, L. Couimon Toad Flax. 

 Nullawarre (Allansford), J. Carter, March, 191-3. A garden 

 plant previously recorded as a naturalised alien in the East of Vic- 

 toria, and now also recorded from the West. 



MiCROCALA FiLiFORMis, H. and L. "Slender Microcala." (Geutianaceae). 

 Linton, Victoria. H. B. Williamson, No. 1484, November, 1912. 



MicKOCALA i^UAURANGULARis, Griseb. " Quadrate Microcala." 

 Agricultural High School, Ballarat, E. J. Semmens, November, 

 1912; Wangaratta, Victoria, E. E. Pescott, September, 1901. 



This interesting genus is small both in size and species. M. fili- 

 formis is native to the Mediterranean area extending from North 

 Germany to Asia, while M. quadrangulori^ is native to South 

 America, and also occurs in California, possibly as an introduction. 

 Externally tlie plant suggests the native Sebaea ovata, and the 

 Wangaratta specimen from Walter's collection was placed under 

 that species as a small form of *S^. ovata. The former has, however, 

 a cup-like quadrangular calyx, while the latter has the calyx divided 

 to the base.
