62 MISSOURI BOTANICAL GARDEN. 



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. Carriere,f and following 

 him, Mr. Baker, % 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 Carriere, but is what is here called Y. Arkansana or 

 Y. tenuistyla, or both. It is interesting 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
