288 NATURAL SCIENCE. Oct., 



Habitat : Region of the Mediterranean and South Russia — 

 fields and hills. 



2. Ziziphoya tenuior (Linn.), Figs. 5-10. 



A herbaceous annual. The flowers are in few-flowered axillary 

 verticillasters, forming a spike. The calyx is like that of Z. capitata, 

 but more hairy externally. The movement is similar to that of 

 Z. capitata. Both the floral leaves and calyces, which when dry are 

 turned up round the main axis, bend out when wet away from it, 

 and the calyx-teeth open. 



Habitat : Region of the Mediterranean and South Russia — hills 

 and uncultivated fields. 



3. Ziziplwra hispanica (Linn.). (Only a herbarium specimen of 

 this was examined.) The stem is branching and herbaceous ; the 

 flowers grow in dense spikes. The movement is the same as in 

 Ziziphora capitata. 



Habitat : Spain. 



4. Ziziphora taurica (Bieb. Fl. Taur. Cauc). (Herbarium 

 specimen.) 



The flowers are in long leafy spikes ; the movement the same as 

 Z. capitata. 



Habitat : Mount Taurus. 



5. Bnmella hyssopifolia (Lam. fl. fr.). 



The movement is the same as that of B. vulgaris described by 

 Verschaffelt. 



Habitat : Region of Mediterranean Europe — open, dry places. 



6. Lallcmantia pcltata (Fisch. et Mey.), Figs. 11-14. 



An erect herb, with six-flowered verticillasters in the axil of 

 sessile bracts. In fruit, the tubular calyces are nearly erect, and the 

 bracts subtending them are folded up so as partially to enclose them. 

 The pedicels of the calyces are flat and broad, being compressed 

 in the median plane. The teeth are unequal, the posterior one being 

 much the largest, flat and slightly curved forward over the four 

 anterior teeth which almost close the mouth. In consequence of wet, 

 the bracts and calyces bend down and outwards from the main stem 

 until the axis of the calyx is at about an angle of 45 degs. At 

 the same time, the four anterior calyx-teeth move slightly apart 

 so that the opening is enlarged and the nuts are shaken out much 

 more easily than when dry. 



Habitat : Persia, Armenia, near the Euphrates, Kurdistan, 

 Mount Elburz. 



II. — The axis of the calyx points more or less downwards, and 

 in consequence of wet it bends up until nearly horizontal. Salvia 

 hormimuii, described by Verschaffelt, is the most marked example of this. 



I. Ocimiim [probably campechianuin] (Mill), Figs. 15-19. 



The stem is erect ; the flowers are arranged in six-flowered 

 verticillasters. The calyx when in fruit is bent downwards. The 

 posterior tooth is broad and obtuse, with winged and decurrent
