alone the two were formerly known, for their guide : " a 

 spathe with an obtuse tridented outer valve " being made 

 the diiferential mark of the first, and ** a spathe with a 

 spear-pointed entire outer valve" of the latter: marks that 

 mutually occur throughout the genus in the spike of the 

 same plant, the outer valve being often entire at the bot- 

 tom of the spike, while it is indented at the top. For real 

 points of distinction between the species we must have re- 

 course, first : to the colour of the flower, which is tawny in 

 securigera and yellow in Jiava; secondly: to the irregu- 

 larity of the same, which is greater in Jlava than in the 

 other; thirdly: to the breadth and inequality of the seg- 

 ments, which are much broader in securigera, and more 

 unequal mjlava. Tlie two being however now represented 

 by good figui-es, can for the future cause no confusion.

The r^resentation of securigera (Giadiolus securigera), 

 in Curtis's Magazine (No. 383), is characteristic and every 

 way worthy of so excellent a botanical draughtsman as 

 Mr. Sydenham Edwards.
