which emphasis requires to be put in connection with the remark is 

 that this striking " similarity, nay rather identity, of the shore vegeta- 

 tion " is due less, as Mr. Kurz appears to imply, to the general connec- 

 tion that subsists between the Andamans as a whole and Burma- 

 Malaya as a whole than to a special connection that subsists between 

 Diamond Island as the first segment, and the Andamans as the contin- 

 uation of a special geographical district whereof both are memhra 

 disjecta — a connection quite as strikingly exhibited in these features 

 wherein they together differ from Burma and Malaya as in the features 

 wherein they alike agree with those two areas.

The account of the Indian Labiate in the Flora of British India, 

 vol. iv, pp. 604 — 705 was published in August 1885, and since then a 

 number of forms new to India, including a few new to science, have been, 

 reported from outlying portions of the Indian Empiie. Having been 

 directed by Dr. King to arrange the Indian material of the order pre- 

 served in the Calcutta herbarium, and having had at the same time the 

 advantage of the use of the material of the order in the Saharanpur her- 

 barium, kindly lent for study by Mr. Duthie, as well as of that in the 

 private herbarium of Dr. Watt, kindly placed at my disposal by its 

 owner, I have taken the opportunity to provide diagnoses of all the forms 

 new to India arranged according to the method of the Flora and now 

 present these to the Society in the hope that they may prove of interest 

 to members who may be botanising in the field near the various Indian 

 frontiers.
