filiferous-leaved plant, said to have been introduced a few 
years before from the Carolinas, by Mr. Lyon, and to have | 
been confused, up to the time of its description, with Y. 
angustifolia* (for which the prior name Y. glauca is now 
commonly employed). The good illustration that he gives, 
and which is copied by Hemsley, shows, as the description 
indicates, that the plant is quite of the habit of Y. glauca, 
with similar narrow leaves and violet-tinged greenish flowers 
having the swollen green stigmas of Y. glauca; but the 
panicle is much branched below, the rather long branches 
reaching about to the top of the uppermost leaves, and the 
flowers are subglobose, with broad blunt perianth segments, 
in neither of the latter respects, however, differing from 
some specimens of Y. glauca. 
Yucca stricta, ever since its establishment, has been a - 
puzzle to botanists, partly because no plant exactly cor- 
responding with Sims’ figure seems to have been reported 
since then, and partly because M. Carriére,t and following 
him, Mr. Baker,t confused with it a garden plant, which, 
in fact, appears to be Y. Louisianensis. In his article in 
The Garden,§ Mr. Hemsley copies the original illustra- 
tions of both forms, though treating them as pertaining 
to one species. Both Baker and Hemsley mention her- 
barium specimens collected by Drummond in Texas and 
near New Orleans, as representing their Yucca stricta, 
which Mr. Baker subsequently called Y. angustifolia var. 
'Y. stricta || and which cannot well be the stricta of Sims or 
‘of Carritre, but is what is here called Y. Arkansana or 
Y. tenuistyla, or both. It is interestmg to note that 
although much collecting has been done in the South 
Atlantic region since the time of Sims’ publication of 
Yucca stricta, no green-styled species of the alliance of
