The present plant is the true Yucca angustifolia of Pursh, 

 and different from the one which has been usually so called in 

 our collections, and which we have already published under 

 the name of stricta (No. 2222). The scape of angustifolia 

 is simple; the leaves are still narrower recurved, and the 

 threads on their margins very much longer; the Iaciniae of 

 the corolla more acute; and it is altogether of humbler 

 growth. Pursh described his plant from Nuttall's herba- 

 rium ; and our plant was raised from seeds brought over by 

 Mr. Nuttall, and presented to our friend Aylmer Bourke 

 Lambert, Esq. in whose garden at Boyton it flowered in July 

 1820. Our specific character is chiefly a version of that given 

 °y Nuttall in his work above referred to, which, though 

 small in bulk is weighty in valuable matter.
