In the remarks of the above table I have used the word 

 tropical of tropical heat. 



The Malayan species appear to be 100. I have arrived at the 

 numbers of species by comparing Miquel with Mr. Kurz' authen- 

 tic specimens from Java, and by making a rough reduction of 

 the numbers so that the Malayan species may be aaquipollent 

 with the Indian species as near as I can guess. 



The comparison between my distribution and Mr. Benthan's 

 is greatly invalidated, because he has made a line at the base of 

 the Himalaya on its southern face to be the boundary of his 

 Tropical Asiatic Region : whereas my boundary of India on the 

 north is the political boundary. I would have made a separate 

 table of distribution of my Indian species on Mr. Bentham's lines 

 f or the sake of comparison : but I cannot make his table of numbers 

 fit with the southern base line of the Himalaya : thus the 5 species 

 of Myriactis are all placed by Mr. Bentham in his Tropical 

 Asiatic Region, whereas it is quite a High Himalayan genus : 

 Solidago is not admitted as a Tropical Asiatic plant though it 

 runs down to the very edge of the Malayan Mora : all the 

 Conyzas appear as Tropical Asiatic, though three of the Indian 

 species are confined to the very High Himalaya. I do not make 

 these remarks by way of criticism : my political line is perhaps 

 as arbitrary a boundary as Mr. Bentham's : and I have put many 

 of my numbers of species arbitrarily : but I do not know in what 

 way Mr. Benthamhas decided on theplacing of his species ; i. e., 

 as regards very numerous species I do not know whether Mr. 

 Bentham has included them in his numbers for Europaso-Asia 

 or f or Tropical Asia as only the total species are given. 



In criticising Mr. Bentham's notes on his Tropical Asiatic 

 Region (Linnaaan Journal Botany, XIII, p. 546) I may note that 

 Athroisma is mentioned as a plant having a restricted station on 

 the Mlgherries. I never saw it there, nor is there a trace in the 

 Calcutta Herbarium, nor in any other collection I have seen that 

 Athroisma is found there : indeed it seems improbable (from the 

 known habitat of Athroisma) that it has been or will be found 

 on the Nilgherries. Athroisma is found in Central Bengal (less 

 than 100 feet above sea) along the banks of the Ganges : in 

 the adjoining plain of north Bengal, extending into the 

 lower plain of Assam : southwards it has been found in the 

 Rajmahl Hills (less than 500 feet above sea) close to its principal
