34 MISSOURI BOTANICAL GARDEN. 



Some time after this, John Saul, of Washington, sent 

 flowers of Hesperaloe, from the Nueces river, to the editor 

 of The Garden, under the name of H. yuccaefolia* and 

 at about this time the genus seems to have gone into one 

 or more English gardens, probably from this source. f 

 The same form apparently was again introduced into En- 

 gland in 1888, % but I have not learned from what source. 



Dr. Watson, in his revision of the North American 

 Liliaceae, shortly after the discovery of H. Enrjelmanni, 

 mentions this proposed species as from the same region as 

 //. yuccaefolia, but imperfectly known, though perhaps 

 to be distinguished by the more slender and flexuous 

 branches of its inflorescence, smaller bracts, twice longer 

 anthers, and stouter included style scarcely longer than 

 the ovary. A similar equivocal mention was made in 

 1880 by Mr. Baker, of H. Engelmanni, which is ignored 

 by Professor Engler, but distinctly recognized by Pro- 

 fessor Coulter in his Botany of western Texas, in connec- 

 tion with the earlier species. 



So far as the evidence goes, all of the Hesperaloe culti- 

 vated in Europe, and to which reference has been made 

 above, belongs to this second form, and may perhaps have 

 been derived from Krauskopf 's original collection. 



In May, 1900, a plant procured some three years before 

 fromMr.P.J.Berckmans,1f and itself possibly derivedfrom 

 Krauskopf, originally, came into bloom at the Missouri 



* Garden. 18: 188. From the phraseology of a quotation from Mr. 

 Saul, it may be inferred, perhaps, that the plant bearing these flowers 

 was derived originally from Krauskopf.
