pubescent, branching from the base with rigid tufted stemlets again 

 decussately branching, leaves small elliptic subentire, heads few-fid.

Rootstock stout woody, stems 10 — 12 cm., branches 3 — 5 cm., leaves 

 Id mm. by 6 mm. apical third obtuse crenate, crenations shallow basal 

 Wo-thirds cuneate entire, bracts 6 mm. by 3 mm. entire or slightly 

 crenate at apex, calyx 6.5 mm. (tube 6 mm.), corolla 8 mm. Dr. Alcock 

 has described this species in the field, his notes say inter alia " leaves 

 " greyish green, odour highly aromatic, taste very bitter, flowers yellow ; 

 " not met with below 5000 feet on the Suleiman hills." It is most 

 nearly allied to T. leucocladum from Arabia and T. cuneifolvmn from 

 Crete. 



[In conclnding the Writer has to acknowledge his great indebtedness to Mr. 

 W. B. Hemsley, f. e. s. who has kuadly compored specimens of the majority of 

 the species here described with specimens at Kew. As is always the case thei-e are 

 a few points whei'eon opinions differ and in view of the fact that Mr. Hemsley's 

 experience and skill are much the greater, the writer feels it only just to mention 

 the chief of these, since they affect the systematic value of the plants concerned. 



Mr. Hemsley thinks that Plectranthus Brandisii (p. 296) might really be united 

 to P. Stracheyi and that Scutellaria andamanica (p. 307) may be only a form of 

 S. ohlonga ; he believes too, that the two forms of Zataria (p. 300) are not specif- 

 ically distinct but that the two forms included under Nepeta glomerulosa (p. 304) are. 

 In the two last cases Mr. Hemsley is almost certain to be right ; in the two first 

 it is possible that the writer has laid too great stress on the fact that both plants 

 exist at elevations, and flower at seasons of the year different from those charac- 

 terising the species which they respectively resemble. These characteristics may be 

 only due to their rather remote geographical areas ; in any case Scutellaria andaman- 

 ica and Plectranthus Brandisii may be looked an as representative of S. ohlonga 

 and P. Stracheyi respectively. Still the corolla of S. andamanica is somewhat 

 different from that of S. ohlonga, and the calyx of P. Brandisii from that of P. 

 Stracheyi. The prominent ruby-red glands characteristic of the outer surface of 

 the calyx and under surface of the leaves of P. Stracheyi are absent from P. 

 Brandisii which has leaves exactly like those of P. Walkeri and a calyx like that 

 of P. Stochsii. 



On the other hand the writer believes Di/sophylla communis (p. 299) to be only 

 a form (hardly distinguishable as a variety) of D. auricularia.^
