an umlaut. In a similar way they altered Iantha, Iochroma, lone, 

 lonidiiim, Ionopsis, and similar names by substituting a j for the 

 initial i. The idea underlying the change was apparently to indicate 

 that the letter has the value of a consonant, but P. W. Myles, who 

 was an authority on classical pronunciation, stated that the initial 

 i in such cases formed a separate syllable (Nicholson, Diet. Card, iv. 



307, 308). n tt ... 



As the result of the change, Dalle Torre and Harms merged all 

 genera commencing with i or j in one alphabetical series in their 

 index, which is not very convenient. The list of Nomina conservanda 

 recognized by the Vienna and Brussels Congresses was arranged in 

 accordance with the Genera Siphonogamarum, and adopted the same 

 spelling. It does not appear, however, that the change from i to j 

 was actually sanctioned by either Congress, and it seems desirable 

 that the question should be decided at an early date. _ 



Typographic or orthographic errors have occurred in the following 

 cases, and require to be corrected. Quercus castanopsisifolia Hayata 

 should become Q. castanopseifol/a, but castanopseojjhylla would 

 have been better. Glutei benyhas Linn, should be G. renghas, as 

 the vernacular name of the tree is rengas, and benghas is meaningless. 

 Dombeya mupanqce K. Schum. was collected by Kirk at Shupanga, 

 and should become D. shupanga. Dracaena bracliystacnys Hook. i. 

 is a typographical error for B. trachystacliys, owing to an uncrossed 

 t hav'ing been mistaken for a b. Hooker described the species " from 

 one leaf and a portion of a panicle," and stated that the panicle was 

 apparently very large, with scaberulous branches. Similarly Globba 

 brachycarpa Baker is a typographical error for G. traclrycarpa, and 

 Hetceria alba Ridl., which is a tall plant with yellow fowers, should 

 be H. alta. For the last three examples I am indebted to Mr. H.N. 

 Bidley.
