The three plants enumerated above appear at first sight very di- 

 stinct ; but on a closer examination of a great number of specimens I 

 am induced to consider them as mere varieties. The floral leaves 

 often fall off" before the flowering is far advanced, so as to change 

 much the aspect of the plant. Dr. Roxburgh's MS. description of 

 T. stoloniferum appears to refer to this species, which is however quite 

 distinct from the plant to which that name is given in Dr. Hamilton's 

 herbarium. # 



Hab. « in Sillet. /3 Napalia, Kamaon et Sirmore. y Taono- Dono-, 

 mons prope Avam. 



* In Ajugoide(E, as in Menthoidece, the Satureinea, and most other Lahiata:, 

 the stigmata are minute, and placed on the inner side of the extremity of each 

 division of the style. 



2. T. Royleanum (Wall. Cat. Herb. Ind. n. 2027), tomentoso-vil- 

 losum, foliis petiolatis, ovatis, basi subcordatis, serratis, subtus tomen- 

 tosis ; floribus subsecundis, spicatis ; spicis abbreviatis, axillaribus • 

 calycibus bilabiatis, dentibus 3 superioribus ovatis, 2 inferioribus 

 acutis; corollae tubo exserto, labio calyce duplo triplove longiore 



Afiine T. quadrifario, sed statura humilius videtur, etcharacteribus 

 datis satis distinctum. • 



Hab. in monte Choor. (/. F. Royle.) 



3. T. tomentosum (Heyne MSS. ex Wall. Cat. Herb. Ind. n. 2025) 

 herbaceum (?); caule tetragono, dense tomentoso, ramoso ; foliis petio- 

 latis, ovatis, basi attenuatis, duplicato-serratis, subtus dense tomento- 

 sis; panicula ampla, ramosissima ; floribus secundis ; foliis floralibus 

 bracteaeformibus, ovatis, calyce brevioribus ; calyce bilabiate, den- 

 tibus 3 superioribus ovatis, 2 inferioribus acutis ; corollee tubo in- 

 cluso, labio calyce vix duplo longiore.— Z paniculatum, Herb. Madr. 



Caulis, ut ex speciminibus videtur, herbaceus, erectus ; panicula 

 amplior, ramosior, spiculis singulis brevioribus, floribus numero- 

 sioribus quam in T. stolonifero et quadrifario. Folia latiora, minus 

 rugosa, basi attenuata vel truncata, nee cordata ut in T. quadrifario

 laxe spicatis; spicis pubescentibus, paniculatis; foliis floralibus 

 bracteaeformibus, calyce subbrevioribus ; calycis dentibus 3 supe- 

 rioribus ovatis, obtusis, 2 inferioribus lanceolatis, acutis; corolla tubo 

 incluso, labio calyce duplo longiore.— 7". Massiliense, Lour. Fl. Coch

 gustiora, basi attenuata.

 norum superiorum subsolitarii, a spica remoti. Folia floralia infe- 

 riora caul in is conformia, superiora subsessilia, ovato-oblonga, grosse 

 dentata. Calyx profunde 5-fidus, lobis lanceolatis, foliaceis. Corolla
