 examples of that species in the Museum at Berlin), were cap- 

 tured by Scnhur ]\Iouiz, iu the houses and shops of Fuuchal, 

 diu-ing the summer of 1858; aud I may state that I have my- 

 self taken it in similar positions iu the Canary Islands.

2. NoTOPHvEXA. 



I propose this genus for a separate group, with flowers di- 

 stinguished by the same peculiarity as those of Colletia — the 

 total absence of petals, — but differing from the latter genus in 

 its habit, its copious foliage, and in the form of its disk, which 

 resembles that of Discaria. It is also characterized by the 

 peculiar feature before alluded to — the union of tlie base of the 

 opposite stipules, which gives an appearance of an articulation 

 at every node, — a peculiarity often seen also iu the middle of 

 the spines when they arc foliiferous. The type of the genus is 

 the Colletia serratifolia of Yeutenat, from Chile ; the other species 

 are mostly from the southern parts of the same country, and one 

 is from New Zealand : hence the generic name, from v6ro<i, auster ; 

 (^aivofiai, appareo. They sometimes form very leafy shrubs, 

 at other times low decumbent bushes, bare of spines. Here we 

 generally see a spineless branchlet issuing from below each spine, 

 and bearing both leaves and flowers, which quite confirms the 

 supposition that the scaly tubercle seen iu Colletia and other 

 genera is only a very abbreviated or suppressed branchlet,
