LuzuLA RACE^iosA, Desv.y var. humilis = L. humilis, BucTien. in 

 AhhandL Nat, Ver. zu Bremen^ 1874, 125. Above Casapalta, 

 about 14,300 feet ! This plant, which bears a striking resemblance 

 to our European L, spicata^ appears to differ only in its smaller 

 size and more contracted inflorescence from i. racemosa^ as the 

 learned author of the species, to whom we are so much indebted 



for our knowledge of the South American Juncacecs^ appears 

 finally to hold. See ' Kritische Zusammenstellung der bis jetzt 

 bekannten Juncaceen aus Siid-Amerika,' by Franz Buchenau, in 

 the 6th volume of the Proceedino^s of the Bremen Natural 

 History Society. 



LuzuLA CHiLENsis, Nees et Meyen^ var. ? Chicla I I found 

 but a single specimen of this curious plant, which does not closely 

 agree with any of the described species, although I have been 

 able to compare it with authentic specimens of nearly all of them. 

 The stem is about a foot in height, with several broad flat leaves, 

 villous, especially at the opening of the sheath, and passing 

 gradually into the bracts at the base of each spike. Of the latter 

 there are three, few-flowered, lax and interrupted. So far, as 

 well as in the hexandrous flowers, this agrees well with Z. cliilensis 

 of Nees and Meyen; but the segments of the perlgone are much 

 longer and sharper, and dark brown m colour. The scarious 

 bracts are very conspicuous, broadly ovate, and tapering to a long 

 point, twice the length of the flowers, and covered, or at least bor- 

 dered, with white villose hairs. In examining the South American 



specimens of this genus in Kew Herbarium, I have been struck 

 by the great degree of variation in nearly all the organs, and I 

 suspect that it may hereafter be necessary to reduce the number 

 of species. Although they are very unlike in appearance, there 

 is little difference in structure between L. chilensis and L. alope- 

 curus^ Desv.
