ME. N. E. BROWN ON SOME NEW AROIDE^. 259 



This species is allied to T. Wightii, Schotfc, which, it resembles 

 in the form of the leaf, but differs in its very much smaller 

 spathe, and especially in its anthers, which are not more than 

 half as long as those of T. Wightii and have a roundish outline, 

 whereas in T. Wightii they are most distinctly oblong. The 

 first leaf, or the leaves of young plants, seem to be sometimes 

 oblong-acute or acuminate, sagittate at base, with short rounded 

 auricles. 



As to T. Wightii, Schott, I do not agree with Engler in con- 

 sidering it a variety of T. crenatum, Bl. ; and he is decidedly 

 wrong in quoting Arum crenatum, Wight, as a synonym of 

 T. Wightii, as that is the very plant upon which Blume founded 

 Theriophonum crenatum, aDd in my opinion is quite distinct from 

 T. Wightii ; of this latter there is but a single specimen (the 

 type !) in the Kew Herbarium, which Prof. Engler has not seen. 

 The two species may be distinguished by the following charac- 

 ters : — 



Theriophonum crenatum, Blume, Mumphia, i. p. 128. 



Leaves roundish oblong, or deltoid-oblong, or deltoid, cordate- 

 sagittate, or sagittate-hastate at base ; front lobe nearly as broad 

 as long, or sometimes broader, very obtuse, apiculate ; basal lobes 

 short and roundish, or rhomboid-oblong. Anthers with a very 

 short beak, much shorter than the cells, which, taken together, 

 are as broad as long, or rather broader, and somewhat roundish 

 in outline. Lower neuter organs l|-2-^ lines long. — Arum crena-

Leaves distintyo hastate, the front lobe about twice as long as 

 broad, acutish ; lq 1 lobes rhomboid-oblong, obtuse, not deflexed. 

 Anthers twice as * 'e as those of T. crenatum, with a long beak, 

 which is as long, or ger, than the cells; the cells, taken toge- 

 ther, are longer tk _ broad and distinctly oblong in outline. 

 Lower neuter organs 3-3^ lines long, twice as stout as those of
