A NEW SALICORNIA.

BY IVAR TIDESTROM.

On August

^6, 1912, Messrs.

Kearney and Shantz

^collected

some very

interesting plants ⁱⁿ the

Toele

_Valley,

some

three

miles northwest

of Grantsville,

Utah. The

_place

where

the plants

grew

^issituated

^south

^{of the}

^Great

^Salt

Lake and near the

base of the

Stansbury Range. The

principal species ^col- lected

bore

_{the aspect} of the desert flora

—

the

Chenopodiaceae and Compositae being

well represented.

In

the collection there is

a

_species of Salicornia hitherto

unknown,

^for

^which

^thefol-

lowing name and

diagnosis are

proposed:

Salicornia utahensis.

Perennisbasi lignosa,

2dm.

_plus minusve alta; caulibus pluribus de- cumbentibus^velerectis, ramiserectiusculis; articuliseaulium 15-18

mm.

longis, 3-5

mm.

_crassis,

ramorum

tenuioribus; spicis7-10articulatis, 15- 20

mm.

_longis, crassitudine _plusminusve4

mm.

Type ^{in the} U. S. National Herbarium,

Kearney and

Shantz, No.

3249, collected near the shore of the Great Salt

Lake

in strongly^saline soil, moisttothesurface.

Distinguished from Salicornia

ambigua and

^S. subterminalis (theone ofthe _Atlantic, theotherof the PacificCoast)

by

^itsshort,thick_spikes.

Intheformerthe spikes are from 18-20 _jointed, while in thelatter the

number

_{of joints} is 13ormore, consequently

much

longer than in our species, while the thickness of the spikes ⁱⁿ the old _species isscarcely

more

than one-halfofthatof S. utahensis.
