or greenish, partly tinged with pink, in one-sided cymes. Very com- 

 mon in Salsette and the Konkau generally. Chaiullidra. 



A. ovnta,*— A large handsome plant, with soft-downy leaves, ovate, 

 crenate; flowers in dense whorls, spiked light 'with deep purple 

 lower lip. 



Common in Guzerafc, Deccan and Konkau, 



7. Leucas, — Generally hairy or woolly plants of no beauty ; 

 flowers white ; upper lip of corolla erect, hooded, lower spreading, 

 with very large middle lobe; calyx with 6 to 10 teeth. 



L. sfclligera, — A tall plant with flowers in large dense whorls ; calyx 

 with 10 soft and spreading teeth. Ghaut, Konkan, &c. Very common 

 at Matheran. Burumbi, Guma. 



L.aspera, — About 6 inches high, rough andhairy; whorls of flowers 

 small aud dense ; calyx curved, with oblique mouth and short teeth. 

 Ttimba. 



Common on the seashore, phiins of India. H. 



L. linifolia, — Very like the last, but larger and nearly smooth; 

 leaves linear or oblong. 



This is the common species of cultivated fields in Guzerat, Deccan 

 and Konkan. 



There are several other species less common, one only. 

 L. biflora, — With flowers not dense. The genus is very easily 

 known. 



8. Leonotis, — Flowers in dense axillary and whorls, with many 

 slender bracts; upper lip of corolla long hooded, lower very small, 

 spreading, concave ; calyx 8 to 10 toothed.

 coloured, hairy; calyx teeth bristly; leaves ovate, crenate. Matisul, 

 ckri. A doubtful native, but tolerably common and very con- 

 spicuous. 



In conclusion, I ought perhaps to say that I assume that any one 

 wishing to identify a plant by the aid of these notes will first set to 

 work to make out the order to which it belongs, then the genus : 

 will, in fact, work downwards from the greater divisions to the 

 lesser. This method teaches one much more than merely running 

 through all the species in the hope of hitting on the identification 

 by some one or two marked features. And speaking more generally, 

 I should say that I hold to the natural orders most faithfully, only 

 wishing that other descriptive helps should be added to aid the 

 student in what must always be to the beginner the very difficult
