Hab. Muthuata, one of the smaller Feejee Islands. 



A tree or shrub (the size unknown), glabrous throughout. Leaves 

 chartaceous in texture, pellucid-punctate, opposite, oblong or elongated- 

 oblong, acute or acutish at both ends, entire, or the margins somewhat 

 undulate, 3 to 5 inches long, li to 2 inches wide, bright green and 

 rather shining above, scarcely pale underneath, inconspicuously 

 feather-veined and reticulated, long-petioled (the petioles about li 

 inches in length). Peduncles axillary, very short, 4 or 5 lines long in 

 fruit, apparently simple and very feio-flowered. Flowers not seen, 

 except the persistent calyx, corolla, and filaments under the base of 

 the fruit, to which they are closely appressed. Both the calyx and 

 corolla are cinereous externally with a close pubescence. The former 

 is four-lobed ; the lobes short and obtuse : the latter of 4 oval or 

 oblong petals of thickish texture, 2 lines long, twice the length of the 

 calyx. Persistent filaments 8, flattened, dilated-subulate, ciliate below 

 the middle, occasionally still bearing small two-celled anthers. Fruit 

 ovoid, slightly pointed, 6 to 8 lines long, minutely tomentose or canes- 

 cent, four-celled, with either one or two seeds in each cell ; the very 

 thick walls between corky and woody in texture, but the rind probably 

 fleshy, so as to be more or less drupaceous when fresh : the endocarp
