106 flora indica, [Anonacea*. 



This genus was established as a section of Folyalthia by Blume, who, however, 

 only described one species. It is so well marked, both in characters and habit, that 

 we have no hesitation in regarding it as a distinct genus. The thick, strictly val- 

 yate, and broadly-clawed inner petals, closely connivent into a mi triform cap, occur 

 in no other genus. The nearest approach to this structure is found in Oxymitra 

 among Guatteriea ; but there the inner petals are not unguiculate. The species of 

 Goniothalamus appear for the most part to be undershrubs, rarely rising to the size 

 of trees. The leaves of many are very thick and coriaceous ; but the thinner-leaved 

 species and the young leaves of the others are pellucid-dotted. The nervation is pe- 

 culiar, the principal veins being connected by loops, which often form a very con- 

 spicuous intramarginal nerve. Many of the species are unfortunately very imper- 

 fectly known, and we are by no means satisfied with the diagnoses given, our materials 

 not being sufficient to enable as to form an opinion of the amount of constancy of 

 the characters on which we have relied. "We therefore recommend a careful study 

 of the floral organs of these plants to those botanists who may have an opportunity 

 of observing them in a living state. Goniothalamus appears to be entirely an Asiatic 

 genus. Several species occur among Cuming's Philippine plants, and others will 

 probably yet be met with in the Malayan Archipelago.

The style of this species is shorter and broader than that of those described be- 

 low. In this respect it agrees with G. macropky litis, Blume, the original species of 

 the genus.
