secting, I have not been able to ascertain whether the anthers are constantly connected even in 

 their young state. Under an ordinary microscope the style of C. lythrifolia appears entire, though 

 by means of a powerful lens a slight fissure may be observed. In C. mariana the fissure is rather 

 more apparent.

This tribe comprehends a large portion of the genera of Labiatae, many of them apparently 

 differing much from one another, but very difficult to reduce further into natural groups. The 

 divisions I have here adopted, for the sake of convenience, are purely artificial.

Dr. Wallich's Indian collection contains 22 species of this genus, of which 17 are new.

Link {Handbuch, p. 479) has formed a separate genus, under the name o{ Phlomidopsis, of 

 the P. tuberosa Linn., giving as the character " calyx dentibus rotundatis sub apice subulatis;" 

 but this is more or less the case with most of the Phlomides, and is so irregular that it cannot 

 form the distinctive mark of a genus. However, the P. tuberosa Linn., herba venti Linn., 

 macrophylla Wall., and probably most of the herbaceous species, might form a separate section, 

 characterised by the calyx naked inside, and by the upper stamina being produced below their 

 point of insertion into a sort of spur. The P. parviflora Wall. cat. herb. ind. no. 20G6, and 

 rugosa Wall. 1. c. no. 20G7, appear to have fleshy achenia, and, if so, form a new genus of the 

 order Prasieae, allied to Gomphostemraa Wall. : but the specimens are too imperfect to determine 

 this point. The P. alba Forsk, and moluccoides Vahl, with neither of which I am acquainted, do 

 not appear, from the descriptions given, to be true Phlomides.

To this genus should be referred, besides the B. cinerea, acetabulosa, and pseudodictamnus of 

 Link (^Handbuch, p. 478), the Marrubium africanum Linn,, crispum Linn., hispanicum Linn., 

 hirsutum Willd., and probably also the INI. orientate Spreng.
