tus, Benth. ex Torr. 550. Zygadenus glaucus, Nutt. 551. Amianthium 

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

 alpine region." (553. See Gentianaceze. ) 



JUXCACE/E. 



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

 Parry. 555. L. pakvifloka, DC. 556. L. comosa, E. Meyer (with a little 

 L. campestris). 557. Juncus triglcmis, L. 558. J. articulates, L., var. 

 jielocarpus, Gray, Man. 559. J. bufonius, L. " Subalpine." 560. J. CAS- 

 taneus, Sm., an alpine form, the same as Parry's 358. 561, 562. J. Alienors, 

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

 360. It appears like a depauperate and attenuated form of J. arcticus ; hut 

 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 (858), H. Engelmann, 

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

 Wikstr. This has " terete flaccid culms." 566. J. Menziesii, R.Br.; the 

 same as Parry's 361 so named, Fendler's 857, Wright's 1924, and Coulter's 

 SOS, the var. Califomicus, Hook, and Arn. Probably an unpublished species. 

 567. J. Bakhcus, Willd. 



568 580. Various Dicotyledonous plants, enumerated above under their 

 respective orders. 



CYPERACEiE. 



581. Fimbristylis laxa, Vahl. 582. Scirpus pauciflorus, Lightf., which 

 Drummond had formerly collected in the Rocky Mountains, and which has 

 been detected at several points along the northern frontier of the United 

 States. 583. S. cjespitosus, L. Also subalpine. 584. Cyperus Scuweikitzii, 

 Torr. "Low mountains, lat. 39."
