capsule, 5-6 mm. long, also appears to be slightly larger than in 
the species and the style slightly longer. 
When von SEEMEN described S. Bakeri he did not compare it with S. 
lasiolepis or mention that species in any way. He published two other species 
in the same paper, S. franciscana and S. ormsbyensis. In neither case did he 
indicate their relationships or mention other species in connection with them. 
We might infer either that American species were not well represented in the 
Berlin herbarium or that VON SEEMEN did not look them over. His description 
of S. Bakeri fits S.lasiolepis perfectly except in the one phrase “apex with short 
gray hairs” in reference to the capsule. All the evidence goes to show that the 
describer was unaware of S. lasiolepis rather than that he knowingly was 
segregating from it a new species with pubescent capsules. This variety is 
comparable to var. puberula under S. commutata. 
Two specimens collected by F. A. Walpole, at Modoc Point, Klamath 
County (2198, 2200), on June s, 1902 (N), are similar to the specimens cited 
later: The capsule in the Klamath specimens, however, is longer (6-8 mm.), 
much resembling that of S. scouleriana. I have considered these two, there- 
fore, to be hybrids between SS. lasiolepis and S. scouleriana. It is possible that 
the plants here referred to var. Bakeri are hybrids also, but this is less probable. 
One Striking character in the Klamath specimens is the elongated pedicel, 
I.5-2.5 mm. in no. 2198, which is longer than in either supposed parent.
