Meteorological Observations. 803 



The establishment of this family appears to me to acquire greater 

 importance, as some at least of the genera Borya, Alnnia, Johnsonia, 

 and Laxmannia, must be referred to it ; these are genera allied to 

 AphyUanthes, which, in the characters of their vegetation, resemble 

 either the Juncece or the Cyperacece, and which have their petaloid 

 flowers accompanied by scale-like persistent bracts, the two superior 

 of which are opposite, almost like the glumes of the Graminece, and 

 are sometimes bifid or trifid, bidentate or tri dentate at the apex. 

 These flowers are also disposed in groups or heads, which, after 

 flowering, present a great resemblance to the heads of ChcBtosiwra or 

 Xyris after their petals have fallen. — Comptes Rendus, 27th August 

 1855, p. 344.
