32 MISSOURI BOTANICAL GARDEN. 



In April, 1900, while passing a day in San Antonio, 

 Texas, I observed a lltsperaloe planted in one of the plazas 

 of that city, which in its long arching concave filiferous 

 leaves, oblong Aloe-red flowers with white styles pro- 

 truding for a distance equal to one-third or one-half the 

 length of the perianth, and very short anthers, agreed with 

 the description and scanty available herbarium material of 

 //. yuccarfolia, and from this plant, offsets of which are now 

 growing in the Missouri Botanical Garden, the following 

 notes have been made. 



The flowers are ephemeral, and their original appearance 

 would scarcely be guessed from the withered remains after 

 they have fallen, or from such herbarium material as is 

 usually seen. Though the buds are erect, the soft, rosy 

 articulated pedicels ultimately arch over, so that the ex- 

 panded flowers are horizontal or more frequently pendent. 

 In texture they are suggestive of Lapageria, and this re- 

 semblance, notwithstanding their smaller size and some- 

 what different form, is increased by their beautiful 

 outward shading with rose-color, on a creamy ground 

 color which prevails on the inner surface. The firm 

 succulent distinct but closely appressed segments of 

 the perianth are about half a millimeter thick in the 

 middle and outwardly recurved near the end, which, as 

 in Yucca, is tipped with a minute tuft of white hair- 

 like papillae. The inner segments are 8 or 9 mm. 

 wide, and the outer segments a little narrower. The white 

 or rosy slightly tapering filaments are adnate to the seg- 

 ments for a short distance and then stand erect, with 

 the very slender apex abruptly incurved so as to make 

 the oblong versatile anthers suberect and introrse, close 

 against the filaments, with their abundant bright yellow 

 powdery pollen exposed toward the style. The conical- 

 ovoid greenish ovary is very slightly 6-grooved, and the 

 white style, somewhat tapering and triquetrous near the 

 base, soon becomes filiform and terete except for three
