THE NORTH-AUSTRALIAN EXPEDITION. 227 



the insertion of the valves of the capsule, a character which I found 

 by far more constant than the relative length of operculum and tube of 

 the calyx. Of the thirty-four species of this collection I have only 

 identified five as known with certainty, and only one (K rostrata), or 

 perhaps two more, as inhabitants of South Australia and Victoria. 

 Should you, Sir William, attach the same importance to this part of 

 my labours, with which I improperly, perhaps, regarded it, I should 

 be very glad indeed to see those species soon appear before the bota- 

 nical public. 



The rest of Myrtaeece, containing diagnoses of three new genera and 

 twenty-four species, are not devoid of interest :— four species of Calyco-

 Harmogia affinis, Schauer ; however, the two genera differ but slightly in 

 the structure of their anthers. Astartea, one species, characterized by 

 the absence of a true pedicel. Callhtemm requires a new study. My 

 Callutemon arborescent, mentioned in 1852, in the 'Linnsea,' is C. 

 brachyandrus, LdL, a plant at the time unknown to me. Amongst 

 Mitchell's plants I notice a gorgeous species, which seems to be very 

 distinct, having nearly persistent bracts. It is the most robust of all, 

 and I send notes on it and two others. Melaleuca contains, this time, 

 only two new kinds, both referable to, Asteromyrtus, if this genus 



should be kept.

The Angophor* are as well marked in decorticatmn aa m structure 

 and texture of bark as Eucalypti, and I have thus been compiled to 

 increase the species to six. Eugenia received three addition, at least
