ers dirty white." — Mr. Wright has sent the same plant from 

 near Austin. The leaves on the flowering branches are from 

 an inch to an inch and a half long ; those of young sterile 

 shoots larger. Tube of the corolla 5 lines long. — I possess 

 no specimen of the original L. albiflora ; from which this 

 apparently differs only as the L. flava /?• Torr. fy Gray, I. c. 

 differs from the type of that species. 1

 tera, A. F'endler, No. 283. — Hooker's A. Oxycedri from the Hudson Bay country 

 appears to belong here : the figure shows at least subsessile, erect fruits ; but the 

 segments of the male flowers are broadly oval, while those of the New Mexican 

 plant are lanceolate." G. Engelmann. 



1 From the collection made by Lindheimer in 1849, Dr. Engelmann communicates 

 the following : 



Symphoricarpus spicatus {Engelm. Mss.): foliis obovatis obtusis brevissime 

 petiolatis supra demum glabratis subtus pubescentibus pallidis; floribus (15 - 30) 

 in spicas axillares arcle glomeratas congestis ; corollis intus barbatis; baccis rubris. 

 — Shady bottom woods, New Braunfels. A small shrub, 2 or 3 feet high, with 

 numerous slender branches. Leaves about three fourths of an inch long, half an 

 inch wide ; the lower leaves wider, almost orbicular. Spikes from 4 to 6, or in fruit 

 8 or 10, lines long. Flowers a little smaller than in S 1 . glomeratus, to which our 

 species bears a strong affinity. It is, however, distinguished by its smaller, obtuse 

 leaves, the spiked flowers, the larger and apparently more juicy fruit, and the 

 broader, more compressed seeds. Of the numerous flowers in each spike only a 

 few mature fruit." Engelm.
