634 RvDBERG : The American Species of 



take as that species was described as having a spur longer than the 

 ovary, which is not the case with P. Unalascheiisis. 



The second species of Pipcrin was first described as PlatantJiera 

 elegans Lindl.* from specimens collected by Douglas in north- 

 western America. It seems from the description as if more than 

 one species had been included therein as for instance " cmile squa- 

 inis parvis ranicntaceis, spica longa densa cylindracca." Although 

 this species has scale-like stem leaves, they are not by far so con- 

 spicuous as in the species that Bolander took for PL elegans and 

 that the spike is described as dense does not very well fit this spe- 

 cies. Not having any authentic specimen I naturally thought 

 that the name Plataut/iera elegans Lindley belonged to the species 

 named Habenaria elegans by Bolander or else the one that I have 

 described here as Piperia multiflora. I therefore described the 

 lax-flowered species under the name P. elongata. At Kew last 

 summer, I found only one specimen collected by Douglas and 

 this I refer to my P. elongata although its spike is more dense 

 than in my type, but not denser than some specimens of the same 

 species in our herbaria. It is, therefore, best to pass my P. elon- 

 gata into synonymy for the present. 



With regard to Habenaria elegans Bolander it must be stated 

 that it was not properly published before it appeared in the Botany 

 of California, for in Bolander's Catalogue of the Flora of San 

 Francisco it is a nouicn nudum, without description or synonyms. 

 What Bolander's plant was is not unknown, for there is one speci- 

 men in the Torrey herbarium collected and named by Bolander. 

 This can scarcely be distinguished from Habenaria Michacli 

 Greene,t although it has a longer, less crowded spike. 



A further study has revealed that several other species than 

 the ones enumerated in the place of publication of Piperia, must be 

 included in that genus, viz., Habenaria Michaeli Greene, and Gyni- 

 nadenia longispica, both mentioned above, Habenat'ia Cooperi 

 Wats.:}: and Habenaria niaritinia Greene. § Concerning H. Cooperi 

 Wats, it may be remarked that it was placed by Watson in that
