190 BOTANY. 



as great as the width. E. Anstralis from Australia, as well as Cicendia 

 from Europe, have stigmas like the American species, but E. 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 Erythrcea are identical with those of a large group of 

 Gcntiai /etc, which comprise perhaps all of Grisebach's Chironiece and Chlo- 

 rcce, being very numerous and very small, from \ to scarcely more than 

 $ mm 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 : Erythema. Eustoma. 



2. Stamens inserted in the throat: Sabbatia. Mickocala. 

 Chloea, Ciiironia, and Seb^ea 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 Erythrcea, distinguished from it only by its small oval anthers, less 

 than 0.5 mm 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 Erythrcea ; seeds i)A mm long, large for the size of the 

 plant. It will have to bear the name Erythrcea pusilla. 



Erythema Douglasii, Gray, Fl. 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 l mm long, style short, stigma about 

 l mm wide ; seeds sub-globose, 0.4 mm in diameter. — Arizona, Utah, and 

 northwestward to Oregon. This plant has been confounded by Mr. Watson 

 with his E. Nuttallii, which, however, is a smaller and more leafy plant, 

 with larger flowers and much larger seeds (0.65 mm long), but much smaller 

 sti» - mas.
