518 ON AN UNDESCRIBED SPECIES OF CRYPTOCAEVA, 



The earliest herbarium specimen of this species extant is in 

 the Kew Herbarium. This was collected by Allan Cunningham 

 at Moreton Bay in 1828. 



The material collected by W. Bauerlen was under observation 

 for some time, and was at first placed provisionally as C. 

 glaucesceiis, var., as it was thought it might eventually work 

 out as one of the varieties of that species enumerated by 

 Bentham (B.Fl. Vol.v. 297). 



As material of these varieties (sic) was identified, it became 

 apparent that some of them were distinct species; and Maiden 

 and Baker"*^ restored Meissner's C. microneura to specific rank. 



When examining the Cryptocaryas in the Kew Gardens 

 herbarium recently, it appeared to me that more than one dis- 

 tinct species was included by Bentham under the name C. 

 glaucescens. It must not be forgotten, however, that Bentham 

 laboured under the great disadvantage of not knowing the trees 

 in the field, and so had only dried specimens upon which to 

 make his determinations. 



As Bentham's type C. glaucescens {loc. cit.) is identical with 

 what is so regarded in Australian herbaria, the way is thus clear 

 to differentiate the various forms at present placed under that 

 species. 



C. glaucescens (type) has an extensive range along the eastern 

 coast, is constant in morphological characters, and is distinct 

 from any other known Cryptocarya; and, so far, I have been 

 unable to trace any intermediary forms. 



This new species differs altogether from C. glaucescens in the 

 shape of fruit, also shape, size, texture and venation of the leaves, 

 and in inflorescence. 



C. microneura Meissn. has thin, long, narrow leaves, and an 

 elongated fruit. 



C. pate7itinervis F.v.M. has also long lanceolate leaves and a 

 very distinct cymose inflorescence, and an oblong fruit.
