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. E’ngelmanni, 
mentions this proposed species as from the same region as 
H. 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. Hngelmanni, 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: 
from Mr. P.J. Berckmans,{ and itself possibly derived from 
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. 
+ See The Garden. 20: 71, 361. 21: 324, where a plant is said to 
have been in continuous bloom from July 1881 until May 1882, with 
promise of continuing to flower for another month or two. — Gard. Chron.
