as great as the width. . Australis from Australia, as well as Cicendia 
from Europe, have stigmas like the American species, but 1. Chilensis (at 
least a specimen collected by Ochsenius in Valdivia, which I refer to that 
species) differs from all the others in having elongated, cuneate, emarginate 
stigmas. : 
The seeds of Erythrea are identical with those of a large group of 
Gentianee, which comprise perhaps all of Grisebach’s Chironiew and Chlo- 
ree, being very numerous and very small, from }to scarcely more than 
3™™ in the longer diameter, and, when fully mature, globose or oval, with 
their surface favose-reticulate. 
The North American genera belonging to this group may be arranged 
thus : 
1. Stamens inserted in the tube: EryrHrma. Eustoma. 
2. Stamens inserted in the throat: Sasnatia. Microcata. 
Cuiora, CurroniA, and Sepa of the Old World also belong here. 
My investigations have convinced me that the genus Cicendia, or at 
least its typical and original species, C. pusilla, is nothing but a reduced 
form of EHrythrea, distinguished from it only by its small oval anthers, less 
than 0.5™" in length, too short to twist much, but still, when drying, some- 
times twisting a little. Its stigma is by no means capitate, but regularly 
bi-lamellate, and, much like that of the American species, triangular-flabel- 
late, and broader than long. The flowers are 4-parted, which often occurs 
in genuine species of Hrythrea; seeds 0.4"™ long, large for the size of the 
plant. It will have to bear the name Erythrea pusilla. 
- Eryturaa Doverasu, Gray, FI. Calif. 1, 480; Syn. 113.—Slender, 
a span to a foot high, loosely and paniculately branched, usually sparse- 
flowered ; leaves from oblong to linear, acutish; flowers on strict, slender 
pedicels, 4-5" wide; lobes of the pale pink corolla obtuse, much shorter 
than the tube; anthers usually only 1”™ long, style short, stigma about 
1™™ wide; seeds sub-globose, 0.4™" in diameter.—Arizona, Utah, and 
northwestward to Oregon. This plant has been confounded by Mr. Watson 
with his EL. Nuttallii, which, however, is a smaller and more leafy plant, 
with larger flowers and much larger seeds (0.65™" long), but much smaller.
