Both varieties are in Mr Douglas' collection from California. 



1. Trillium sessile, L. — Mich. Flor. Bor. Am. I. p. 215. Bot. Mag. t. 40 giganteum; 



foliis floribusque fere quadruplo majoribus. 



The var. /3. only is in Mr Douglas' collection, and what is remarkable, no form of this species appears to 

 have been elsewhere observed on the west side of the Rocky Mountains. The stem is from eight to fifteen 

 inches high, the leaves three or four inches long, and 2i or 3i broad, spotted like those of the plant from the 

 United States. The flowers are from 1\ to 3 inches long, and purple, as figured in the Botanical Magazine.

1. Juncus Menziesii {Brown); caule erecto tereti folioso, foliis lineari-acuminatis supra 

 canaliculatis, capitulis terminalibus globosis 1-3 bractea exteriori plerumque foliacea et 

 capitula superantibus, sepalis ovatis vel oblongis capsulam obovatam nitidam muticam 

 oequantibus dorso viridibus enerviis margine castaneomembranaceo versus apiceminvoluto. 

 — a. Menziesii; sepalis lato-ovatis obtusis. Brown, — Hook. Flor. Bor. Am. II. p. 192 — /3; 

 Californicus ; sepalis oblongis acuminatis, foliis angustioribus. 



We have only the second variety from California. In the Flor. Bor. Am. this was principally distinguish- 

 ed from J. castaneus by the broad sepals of a, and the capsule as long as the perianth. In J. castanem, 

 however, the sepals are only about half the length of the capsule, and are entirely brown, membranous and 

 3-ncrved.
