Mr. J. Miers on the genus Lycium. 



345 



This species seems to have escaped the notice of botanists, 

 although published ninety years ago, as I do not find it included 

 in the lists of any of the earlier authors, nor in Steudel, Walpers, 

 or yet more modern arrangements. The characters given by 

 Jacquin appear to conform with those of Lycium : the only 

 genus with which it is likely to be confounded is Dunalia. It is 

 described as a handsome shrub with crowded leaves, and its 

 flowers must be the largest in the genus. From 5 to 7 leaves 

 are fasciculated in each axil ; they are sessile, tapering from the 

 summit to the base, quite smooth, fleshy, nearly an inch long ; 

 the calyx is 3 lines long, the corolla is slender and an inch in 

 length.

* This plant, found by Meyen in the Cordillera of Southern Peru, has 

 been referred to Lycium and Grabowskya, but it appears to me that it 

 cannot belong to either : its long simple distichous patent branches, termi- 

 nating in a spine, indicate an opposition, not an alternation of its axils and 

 leaves ; its leaves are described as minute, but not as being clustered or 

 fascicled ; the corolla of its sohtary flowers is caeruleous, with a large 

 funnel-shaped limb and small erect segments, together with included sta- 

 mens. There is little here conforming to Lycium or Grabowskya. In its 

 peculiar habit, its minute leaves, its calyx, the colour and shape of its 

 flowers, it approaches more closely to the curious Bignoniaceous plant 

 which I found in the Cordillera of Mendoza, and which I described under 

 the name of Oxycladus aphyllus, a supposition rendered still more pro- 

 bable from the, analogous locality of its oria:in.
