On Certain Spir^ace-e. 



I had long suspected that Bongard's paper on the Vege- 

 tation of Sitka, read in the St Petersburg Academy on the 

 4th of May, 1831, must have been printed and distributed 

 before 1833; in which case it would antedate much of the 

 first vokime of Hooker's Flora. Dr. Otto Kuntze's careful 

 and extensive researches into bibliograpliy have brought forth 

 the fact that Bongard's paper was indeed distributed before 

 the end of 1831. It is therefore inevitable that Lutkea ranst 

 displace Eriogynia. To the species recognized by Dr. Kuntze 

 the following is to be added. 



L. Hendersonii. a low much branched and tufted but 



scarcely matted undershrub: branches leafy at summit only, 

 the leaves crowded but not rosulate, coriaceous and evergreen, 

 spatulate-oblong, entire, acutish, f to | inches long, rather 

 obscurely silky-pubescent or glabrate: peduncles scapiform, 

 an inch or two long, bearing a rather dense cylindrical raceme 

 of small white flowers: carpels 3 to 5, villous along the suture. 

 A near relative of L. ccj^pifosa, O. Ktze., but clearly dis- 

 tinct; inhabiting the Olympic Mountains, AVashington. Two 

 sheets of specimens are in my possession, presented by Mr. 

 Charles V. Piper, who collected them in 1890. The first 

 sheet Avas labelled Spircm cojspUosn, the second Eriogijniii 

 Hendersonii, Canby. I do not find that Mr. Canby has ever 

 published the species. 



SriRjiiA BETUL^FOLiA^, Pall Fl. Ross. i. 33. t. 16 (1781). 



From this Siberian species, all the American species which 

 have latterly been referred to it, are in my opini(m to be 



Issued May 14, 1892.
