Willdenow's and Bartling's types are extant: of the former wc possess a carbon 
impression, of the latter fragments, both secured by Mr. Merrill, who was further 
able to compare them with more recent collections. Both were obtained by the 
same expedition, almost cei-tainly by the same collector, and it is highly probable 
that they are parts of a single collection. Of Meyen's type, we also have a 
carI)on impression, with notes, and it seem.s to differ only slightly from the older 
species, and then in pubescence. Taken in conjunction with numerous recent 
collections, including 6S32, from Polillo, it dues not seem possil)le to maintain 
it as a distinct species. The alliance is unquestionably with H. cougcsta R. Br., 
but it (lifFers from thu only Indian specimen of the latter which we possess, 
Dr. Praia's colfector 57, Andaman Islands, by thu thinner leaves with less con- 
spicuous and more arched venation. It has a rather wide Philippine distribution. 
Hydnophytum formicarum Jack in Trans. Linn. Soc. 14 (1823) 124. 
Represented by 908/,; other distriI)ution Tayaljas, Mindoro, Mindanao, Borneo. 
Java, Sumatra, Andaman Islands, Malay Peninsula. It may be worth adding 
that although the stem-ba^es were of large size and characteristically excavated, 
the few ants within were most peaceably disposed.
