author has not seen an original specimen, but he notes 

 tliat Kihlman had (Medd. Soc. Fl. et Fauna Fennica, xiv, 

 111, 1888). I possess two from the St. Petersburg herbarium, 

 from the author. They bear little resemblance to the 

 Swedish specimens named by Kihlman, but I hope to 

 send them to Dr. Hagstrom. 



P. peetinatux, Linn. — I (juite agree with the author in 

 referring P. eohimhimis, Suksdorf (Deut. Bot. Monatss., 

 xix, 92, 1901) to this, which Mr. H. St. John also does in 

 Rhodora, 124, 1916. It may here be noted that the author 

 uses " turios " for the winter-buds or gemmae, but he also 

 applies this name to the resting-buds on the roots ; but 

 the structure of these is quite different, though they ad- 

 mittedly answer the same end. He divides pectinatus into 

 five varieties and twenty-one forms, placing P. striatus, 

 Ruiz et Pavon, under three of them. The var. mongolicus, 

 Ar. Benn., he thinks may prove a new species, but I do 

 not consider the material is sufficient to so decide. He 

 places P. latifolius (Robbins), Morong, under P. zosteraceus, 

 Fries, but Robbins, in Bot. 40th Par., 338 (1871), distinctly 

 disclaims this, and it is a distinct species and very rare. 

 The "New Jersey"" station given by Graebner, Das Pflanz., 

 Heft 31, 128, 1907, is an error. The only other stations 

 known, besides the two given by Morong, are " Huachina 

 ]\rts., Arizona, 1882, G. Lemmon and wife," "King's River, 

 Lasson Co., California, Watson," Bot. Calif., ii, 1880, and 

 Mono Co., 1898, No. 9915, J. W. Congdon. 



P. Rohbinsill, Oakes (America). — One of the most distinct 

 species in the genus, and with P. Maaclcimius, Ar. Benn., 

 uni(iue in structure. 



P. Manckiaiiiix, Ar. Benn. (Asiatic). — The author remarks 

 oil Dr. Graebner's {I.e.) putting this species near ohtuslfolius, 

 and says it is an error; but I can explain this. Dr. Graebner 

 di'ew Md/ickijinus and named it ocJirc'ifii.s, Raoul (a near 

 ally of (Jjtusifoliiix). Fortunately I saw this in the proof 

 and corrected it, but Dr. Graebner neglected to revise the 

 reference, althougli I pointed out to him that there was 

 this error. 



P. ocJiredfiis, Raoul (Australia and New Zealand). — Dr. 

 Hagstrom makes a "new species (vel subspecies P. odiro- 

 ati {) P. furc'ifa, Hagst." I can well understand his
