84 Writings of Edivard L. Greene. [zoe 



Cardamine cardiophylla Greene as well as the revived syno- 

 nyms C integrifolia (Nutt.) and C. Calif o mica are all apparently 

 forms of the varying C. paucisecta Benth. C ameata Greene 

 known only in immature specimens may belong here also, but 

 the foliage is more dissected. C. integrifolia (Nutt.) is apparently 

 the oldest name. 



Streptanthus Parry i Greene is Caulanthus Lemmoni Wats., 

 the older name. 



Streptanthus niger, peramcenus, albidus, barbiger, Biolettii, pul- 



chelhis, Mildredcs, and seciindus Greene are nearly all separated by 



inconstant characters from 5". glandidosiis. Watson in one of his 



later papers reduced peramoenus and albidus; ptdchellus and 



■ secundus are the same thing from the same locality. 



Thysa7tocarpus ramosus * Greene is T. elcgans F. & M. 



Cerastiiim grande Greene is certainly C. maximuin I^edeb. 



Silene piirpurata Greene, by the description, seems to be 

 S. repens lycdeb. 



Silefie simulans Greene is S. laciniata Cav. 



Alsinella ciliata Greene is Sagina apetala 'L,. 



Paronychia pusilla Greene is Herniaria cinerea I,, another 

 waif from the Mediterranean region. A second species H. 

 glabra was collected by Mr. Congdon, near Darrah, in Mariposa 

 County, some years ago. Mr. Greene might be forgiven for 

 renaming the obscure weeds which make their advent into Cali- 

 fornia if he would but acquire the knowledge necessary to place 

 them in the proper genera. 



Tissa pallida, T. leucantha, T. Taliniim\ & T. valida\ Greene 

 are forms of that species of which the oldest name is, apparently, 

 vtacrotheca. T. Talinum and T. valida are perfectly inexcusable. 



Tissa Clevelandi Greene is rubra, the perennial form. 



Tissa tenuis Greene is Lepigomun gracile Wats, and both are 

 probably referable to diandra and perhaps to still older names. 

 The type of tenuis was collected at Alameda and Dr. Kellogg 

 collected It at the same place more than ten years earlier. It 

 often has four stamens, and is perhaps never truly apetalous ; 

 like gracile it has from one to four small, obovate, hyaline petals
