of the original species, owing to the long and squarrose points of the 

 scales, pale greenish. 



Eleocharis Bolanderi : E. uniglumi sirailis, absque rhizomati- 

 bus repentibus niodo E. multicaulis ; caule tenuiori striato-angulato ; 

 stigmatibus 3 ; achenio albido lasvi pyriformi angulis 3 acutis costato, 

 apice quasi truncato tuberculo latissirao depresso fere disciformi prorsus 

 confluente coronato ; setis tenuibus 3-4 retrorsum scabris achenio 

 2 - 4-plo brevioribus. — Mariposa County, on banks of stream near 

 Clark's, Bolander. Fruit mostly immature in the specimens : scales of 

 the spike dark brown. 



Scirpus (Isolepis) pygm^eus, — preserving the earliest specific 

 name for this common Californian as well as S. American and Austral- 

 ian plant, which was inadvertently named " Isolepis carinata " in an 

 early distribution of some of Mr. Bolander's plants, No. 57. It is 

 Isolepis leptocaulis, Torr. in Bot. Whippl. p. (153) 97. It appears 

 to grow in company with, but is quite distinct from, 



Scirpus (Isolepis) carinatus, the Isolepis carinata, Hook. & 

 Arm, which is near 1. cartilaginea, R. Br. 



Scirpus (Trichophorum) criniger : caulibus e rhizomatibus 

 dense caespitosis strictis (bipedalibus) triquetris, angulis sub apice 

 scabris ; foliis planis, radicalibus angusto-linearibus elongatis, caulinis 

 lato-linearibus brevibus saepius vagina brevioribus; spicis paucis oblongis 

 in capitulum unicum rariusve geminatum arete congestis ; involucro 

 monophyllo subulato vel subnullo ; squamis ovatis tenuibus trinervibus 

 fulvis muticis (infima majore bracteante acuminata vel cuspidata) fila- 

 mentis 3 et perigynii setis 6 tenuibus antrorsum scabris dimidio brevi- 

 oribus ; achenio obovato-triquetro cuspide brevi apiculato. — In bogs, 

 on Red Mountain, Humboldt Co., Bolander. An interesting plant, 

 with nearly the habit and inflorescence of Eriophorum Virginicum, but 

 usually with only one glomerule, composed of 5 to 9 very crowded 

 spikes, and the involucre small and simple or none, and comose with 

 fulvous, but not very tortuous, long bristles and persistent filaments. 

 The number and the serrulation of these bristles refer the species 

 to Trichophorum ; rather than to Eriophorum. The rather broad 

 cauline leaves are from 3 to only 1£ inches long, acute, smooth, or 

 the edges minutely scabrous. 



The Carices of these collections having been referred to Mr. Olney, 

 he has obligingly furnished characters of the following proposed new 

 species, along with two or three of Eastern habitat.
