Ttphonitjm tbilobatum, Schott. 



To the synonymy of this species as given by Engler add : — 

 Engler in Bull. Soc. Tosc. di Ort. iv. p. 301 ; Beprint {Ar. Born. 

 Sf Pap.), p. 15. — T. siamense, Engler in DC. Monog. ii. p. 615. — 

 T. triste, Griffith, Notulce, iii. p. 145. — Arum orixense, Boxb., 

 Lodd. Bot. Cab. t. 422. 



I can find nothing whatever whereby to separate T. siamense 

 from T. trilobalum ; the synonym T. triste, Griff., is entirely 

 omitted by Engler. From his monograph it appears that he has 

 seen very few specimens of T. trilobatum. The following are con- 

 tained in the Kew Herbarium : — 



Ceylon {Thwaites no. 2896! Walker no. 123!); Bengal {Grif- 

 fith no. 5999 ! BZooTc.f. Sf Thomson ! Jenkins !); Assam {Masters) ; 

 Mergui {Griffith no. 5998!); Malacca {Griffith nos. 5996 = T. 

 triste, Griff. ! 5997!); Siam {Schomburgk no. 334 = T. siamense, 

 Engl. !) ; Wallich, Cat. no. 8829 c ! ; Dacca {C. B. Clarke nos. 

 17082 ! 6739 !). 



T. Htjegelianum, Schott, vide iV. E. Broion in Gardeners' 

 Chronicle, 1879, n. s. xii. p. 70, sub Heterostalis Huegeliana ; and 

 Schott, Gen. Aroid. t. 18. f. 4-6. 



Engler, in DC. Monog. Phanerog. ii. p. 618, places this as a 

 variety of T. diversifolium, Wall. It may be so ; but there are 

 differences in the inflorescence that ought not to be overlooked. 



In T. Huegelianum, Schott, the appendix of the spadix is as long 

 and usually very much longer than the rest of the spadix ; the 

 neuter interval (between ovaries and anthers) is covered in the 

 upper part with very small pointed deflexed tubercles, which 

 almost become obliterated in drying. 



In T. diversifolium, "Wall., the appendix of the spadix is shorter 

 than the rest of the spadix, and much more slender than that of 

 T. Huegelianum ; the upper part of the neuter interval covered 

 with short deflexed subulate-pointed tubercles, which are di- 

 stinctly seen in the dried state, and are longer than those of T. 

 Huegelianum. The spathe, too, seems to be smaller than that of 

 T. Huegelianum. 



The only specimens of T. diversifolium I have seen belong to 

 no. 8933 a of Wallich's Catalogue, from Nepal, the type of this 

 species ! No. 8933 b, from Kumaon, is T. Huegelianum, Schott.
