Y. Whippleii, Torrey. A fine plant, which has been drawn by Mrs. 
Thiselton-Dyer, has just flowered and died at La Mortola. I saw 
another which had lately flowered at Hyéres, where it is grown under 
Lemaire’s name of Yucca californica. I now think this had better 
be kept as a genus distinct from Yweca, under Engelmann’s name

D. juncifolium, Hort. Hanbury. This I was very pleased to see in 
flower in a state of full perfection at Monte Carlo and again at Genoa. 
Tt has a great tuft of 200-300 recurving rigid linear leaves, 3-6 feet 
long, not more than a quarter of an inch broad at the middle, vertically 
striated, slightly glaucous and convex on both faces, scabrous on t Le 
Margin, not splitting up into threads at the top. The peduncle is 
15-20 feet long, bearing, in its upper half, dense spikes of minute whitish 
flowers in the axils of great scariose serrated lanceolate white bracts. 
Mr. Watson sent home specimens in fruit of the same plant two years 
ago from Hyères. It may be D. qguadrangulatum, S. Wats., in a state 
of full development.
