SUPPLEMENTARY LIST OF CEDROS ISLAND PLANTS. 267 
somewhat superficially by the present writer in the spring of 
1885 ; again at what he calls the “southwest end,” a part of 
the island which has until now remained unknown. Besides 
furnishing us with fresh and excellent specimens of a few of 
the earlier known rarities of the island, his various packets 
have contained material for the following identifications and 
diagnoses, which may most conveniently be put forth in the 
form of a supplement to the list which ends with page 208 
preceding. 
83. CHENOPODIUM MURALE, Linn., Sp. Pl. 219. 
84. EnroGoNUM TAXIFOLIUM. Shrubby and apparently. 
diffuse, but low, the: slender branches tomentose-canescent : 
' leaves numerous, fascicled, narrowly lanceolate, the margins 
closely revolute, only 3 to 5 lines long, glabrate: involucres 
a line long, few-flowered, arranged in loose virgate somewhat 
arcuate terminal sessile spikes two to five inches long : flowers 
white, a line long; perianth-lobes similar, spatulate-oblong, 
obtuse. ‘ 
From a canon on the eastern side, four miles below the 
northern end; collected in flower in January. A species with 
the vegetative characters of E. fasciculatum, but the inflo- 
rescence virgate. 
85. EnrocowuM Ponpu. Shrubby, stout and low (only 
3— 6 inches high), iutricately branehed, the young branches 
and the foliage white-tomentose : leaves obcordate- or obovate- 
spatulate, 1—2 inch long: involucres 2 lines long, arranged 
in short-peduneled terminal eymose corymbs : flowers white 
or rose-tinted, a line or more in length: outer perianth 
segments round-obovate, the inner oblong, all retuse or 
emarginate. 
Common at the southwestern side of the island ; flowering 
in February. A very well marked and rather handsome 
species, I gladly dedicate it to the discoverer; and with it 
the following new cactus.
