base. Those of Satureia hortensis differ only in having slightly 

 wider basal auricles. The first pair of leaves are broadly oval 

 and entire. 



The ovate-oblong cotyledons of Teucrium Botrys (fig. 595) 

 represent a very unusual form and, as far as I am aware, 

 occur only in the tribe Ajugoideae. The leaves are glandular- 

 pubescent and cuneate at the base, and show an interesting 

 evolution somewhat on a ternary plan. The first pair are 

 simply crenate ; the second pair lobulate ; while the third and 

 fourth pairs are deeply trifid and tripartite respectively with 

 the lobes cuneate and more or less distinctly trifid. The coty- 

 ledons of Ajuga Chamaepitys (fig. 596) are much smaller and 

 oblong, but otherwise conform to those of Teucrium Botrys. 

 The first pair of leaves are oblong or spathulate and entire ; 

 the second pair lanceolate with a tooth on each side; the 

 third and fourth cuneate and trifid at the ends, while the fifth 

 and sixth pairs are pinnatifid. 



The cotyledons of Galeopsis pyrenaica are obovate or 

 oblong-obovate, emarginate, with small ovate or triangular 

 auricles, and thus differ from any of the above types. 



Those of G. Ladanum are also unique in being sub- 

 orbicular, emarginate with a sudden contraction a little above 

 the base of the lamina. The first pair of leaves are broadly 

 ovate and crenate ; while the next two pairs are oblong-ovate. 

 All are penninerved. 



Ocimum Basilicum, L. 



Hypocotyl erect, terete, minutely pubescent, 1-2 cm. long, with a 

 reddish tinge. 



Cotyledons fleshy, unequal, triangular or reniform, emarginate, 

 slightly cordate at the base, petiolate, light green, glabrous except 

 on the petiole ; midrib apparent only at the base. 



Stem short, erect, herbaceous ; primary internodes but slightly 

 developed. 



First leaves simple, cauline, opposite, slightly toothed, ovate- 

 lanceolate, acute, sessile, glabrous, pale green, pimiatinerved. 



Elsholtzia cristata, Willd. 



Hypocotyl erect, terete, finely pubescent, 9-12 mm. long, almost 

 colourless or stained with red.
