drawings, of which there are none of this species from the 

 islands above mentioned, it is not safe to infer that it has 

 so exceptional a distribution. It is the type of the genus, 

 and of the first section, Gandarum, distinguished by its 

 short peduncle, very broad open campanulate spathe, 

 short thick appendix of the spadix, and globose ovaries 

 with long styles. (See t. 2812 and t. 5187 of this Maga- 

 zine.) In the second section Brachyspatha the peduncle is 

 elongated, the spathe short, the appendage of the spadix 

 very long, acute, and the style short. To this section 

 belongs the A. (Proteiophallus) Bivieri of this Magazine 

 (t. 6295). The third section Conophallus has a long or 

 short peduncle, a spathe with a convolute tube gradually 

 contracted into a concave limb, a thick conical appendix, 

 and sessile stigma. To it belongs A. bulbifer (Arum bulbi- 

 ferum, t. 2072 and t ; 2508). From these definitions it 

 will be seen that A. Titanum does not agree with any, but 

 that it comes nearest to Brachyspatha, in which Engler has 

 placed it, and I think rightly, provided the sectional 

 character be slightly modified by disregarding the length 

 of the style and form of the appendages of the spadix?—
