WS, Benth. ex Torr. 55CK Zygadexus glaucus, Nutt. 551. Amianthium 

 Nuttallii, Gray. 552. Lloydia serotina, Reich. "Pike's Peak, in the 

 alpine region." (5^3TSee Gentianaceaj.) 



JUXCACE.E. 



* 



554. Luzula spicata, DC, var. near L. Peruviana; the same as 392 of Dr. 

 Parry. 555. L. parviflora, DC. 556. L. COhosa, E. Meyer (with a little 

 L. campestris). £57. Juxcus triglumTs, L. 558. J. articulatis, L., var. 

 pelocarpus, Gray, Man. 559. J. bufoniits, L. " Subalpine." 560. J. « as- 

 taneus, Sm., an alpine form^ihe same as Parry's 358. 561, 562. J. ai;< tmh, 

 Willd., var. gracilis, Hook. ? Alpine and subalpine. TSe same as Parry's 

 360. It appears like a depauperate and attenuated form of J. arctii : but 

 as most of the cauline sheaths are leaf- bearing, it is probably of a distinct 

 species, so far as I know, yet undescribed. Dr. Lyall collected it, as well as 

 the true J", arcticus, in the Cascade Mountains, farther north. 563. J. arc- 

 ticus, Willd., proper, with leafless sheaths and more less attenuated stems.' 

 564. J. xiphioides, E. Meyer, Well marked by its flattened stems as well as 

 leaves. It was also collected in this region by Fendler (85S), H. Engelmann, 

 and in the Rocky Mountains, farther north, by Bourgeau. 565. J. ensifolius, 

 Wikstr. This has " terete flaccid culms." £66. J. Menziesii, R.Br.; the 

 same as Parry's 361 so named, Fendler's 857, T Wright's 1924, and Coulter's 

 808, the var. Calif amicus, Hook, and Am. Probably an unpublished species. 

 567. J. Balticus, Willd.
