152 THE TASMANIAN FLORA. 



T. coRTMBOStJM, R. Br. An erect branched perennial, usually 2-3 feet high. 

 Stems square, pubescent in most parts. Leaves stalked, ovate, acute, irregularly 

 and coarsely toothed, mostly 1-2 inches long. Flowers in numerous, few- 

 flowered, loose, irregular panicles, dispersed along the ends of the branches. 

 Oalyx campanulate, about 2 lines long ; the teeth acute, and as long as the 

 tube. Corolla white, 4-6 lines long, the 4 upper lobes equal, about 1 line long, 

 the lowest lobe much longer. Nuts pubescent. 



Common in many parts, but principally in dry situations ; also throughout 

 Eastern and Southern Australia. Fl. Dec.-Feb. 



11. AJUGA. 



Calyx-teeth 5, equal. Corolla limb with a very short, bardly apparent, upper 

 lip, and a long spreading lower lip. Stamens 4. Style shortly bifid. Nuts 

 rough. 



The genus is principally found in temperate Asia and Europe. 



A. AcrsTEALis, R. JBr. An erect, or more often depressed, perennial, with 

 numerous branches arising from a thickened rootstock, brajiches seldom 

 exceeding a few inches. Leaves from oblong to nearly linear, all but the upper 

 ones on long stalks, remotely and obscurely toothed, lower ones often 6 inches 

 long, upper ones under 1 inch. Flowers in small, dense, axillary clusters. Caljrx 

 usually very pubescent, mostly 2-3 lines long ; teeth acute, shorter than the 

 tube. Corolla b]ue, variable in size and details, usually about 6 lines long, 

 upper lip from hardly apparent to nearly 1 line long. 



Very common, mostly in fairly damp situations ; also throughout Eastern and 

 Southern Australia. Fl. Dec.-Feb. 



Okdbb LIX. PLANTAOINACEM. 



Flowers regular. Sepals 4. Corolla small, scarious, gamopetalous, with 4 

 spreading lobes. Stamens 4, rarely fewer, inserted on the corolla. Ovary 

 superior, free, 1, 2-4 celled, with 1 or 2 ovules in each cell. Style simple, 

 fi'iform, much elongated. Fruit a capsule, splitting transversely. 



A small order, widely distributed in both temperate zones.
