before their full developement. Pentlandia has no connect- 
ing membrane, and the filaments, when pulled, snap off 
at the point of insertion. Urceolina hasa membrane adhering 
to the tube, but partible, and its edge discernible between 
the filaments; Stenomesson a free and dentate cup. Pent- 
landia and Stenomesson in habit and foliage are closely akin ; 
Urceolina flowers from between the leaves. Oporanthus (of 
which I have a two-flowered scape with two ripe capsules) 
has a naked tube, Chlidanthus a connecting irregularly den- 
tate membrane adhering to the tube, but partible ; Clitanthes 
a cup as perfect as that of Stenomesson. Urceolina and Chli- 
danthus, in which the cup is not manifest, but adhesive and 
imperfect or rather rudimentary, are therefore points from 
which the two sections diverge. The only known genera of 
this section are Pentlandia, Oporanthus, Sternebergia, and 
Gethyllis. Carpodetes has no immediate connexion with 
Stenomesson, with which Mr. Ker wished tounite it, but if it 
could merge in any other genus, that would be Coburghia, 
which in that case, having the priority, it would rather 
supersede.” 
For the whole of this article I have to express my obli- 
gations to the Honourable and Rev. William Herbert.
