This interesting species was first noticed in Oct. 1895, in one of 

 the flower-beds in the Royal Botanic Garden, in which it had appeared 

 spontaneously. A drawing was made and sent with specimens to Kew, 

 where it was examined by Mr. N. E. Brown, of the Kew staff, a very able 

 student of Aroidese ; Mr. Brown agreed with us in thinking it new. 

 No li^ht could be thrown, at the time of its first being noticed, on its 

 original habitat, though its introduction had apparently not been recent, 

 seeing that it was subsequently found, when looked for, in almost every 

 part of the Botanic Garden. The communication of specimens from 

 Myitkyina in Northern Burma seems at last to definitely settle the 

 original source of the species. It is noteworthy that the commonest 

 of the Typhonia in and around the Royal Botanic Garden, Typhonium 

 trilobatum Schott (Arum trilobatum Linn. = Aram orixense Roxb.), is 

 evidently a plant introduced here during or since Roxburgh's incum- 

 bency as Superintendent (1793-1815). Roxburgh did not collect it 

 in Bengal and we have been unable to find it in Bengal ourselves, or to 

 learn that any one has found it in Bengal except in the immediate neigh- 

 bourhood of these Gardens — where it is scarce, and inside them — 

 where it is abundant. Next most common in these Gardens is T. inopina- 

 tum, the species just described, while fairly plentiful but less common than 

 either is a species that during Roxburgh's superintendents hip was acci- 

 dentally introduced from the Moluccas, and that he has described as Arum 

 trilobatum in Flora Indica, iii. 505, but that is not the Arum, trilobatum of 

 Linnaeus, Sp. PI. ed. princeps, though it was included by Linnaeus with 

 the true T. trilobatum in his Systema ed. x. and his Sp. PL ed. ii. The 

 true Typhonium trilobatum is based on a figure by Hermann (Par. Bat.) 

 of the Ceylon "Panuala" which Thwaites, Trimen and others identify 

 with Arum orixense Roxb. whereas Roxburgh's plant is the same as 

 Rumphius' Arisarum amboinicum (Herb. Amboin. V. t. 110, f. 2). It is 

 usual to give the name Typhorium Eoxburghii to Roxburgh's plant, on 

 the authority of Schott, but there is a slight objection to this in the 

 fact that Schott gives a figure of the plant which he names T. Roxburghii
