200 ON SOME NEW MALAYAN CORYLACEiE. 



Q. Amherstiana, Wall. ! between which it should be stationed. 

 The cup-scales are a good deal like those of the first-named species, 

 the foliage approaches that of the second, but both cup and acorn 

 are considerably smaller than m either, and the latter of a much 

 deeper hue.

In insula Lingga, ad oram orientalem ins. Sumatra, coll. 

 Teijsmann. (Herb. hort. Bogor, n. 11457.) 



Evidently very closely allied to C. smnatrana, A. DC, my 

 specimens of which are, I regret to say, imperfect and inadequate 

 for a proper comparison. It apx^ears, however, to differ by the 

 leaves bemg more lepidote beneath, by the peculiar shape of the 

 involucre, the arrangement of the tubercles, and by the manner in 

 which the perfectly smooth nuts are packed in the involucre, which 

 I find invariable, and indicated indeed externally. Though out- 

 wardly uninjured, the nuts were destroyed within, so that I could 

 not, unfortunately, determine the cotyledonar structure.
