pprigonio albo glaberrimo basi subcrassa 6-angulata ; segmentis spath- 

 ulato-oblongis retusis, interioribus jiarum angustioiibus ; tilamentis basi 

 liirsutulis ; achenio eloiigato, angulis scabris. — Southern Utah, Dr, 

 Parry, uo. 245. Plant with much the aspect of E. multiceps, on a 

 larger scale, with mostly triradiate scapes. 



Eriogoxum Pakryi. {Pedunculata, inter subdiv. * et * * in- 

 serendum.) Annuum ; foliis omnibus radicalibus reniformi-rotundatis 

 firmis (subpollicaribus) undique cum petiolo elongato albo-lanatis ; 

 scapo paniculaque effuso-ramosissima ultraspithama^a glandulis viscosis 

 parvulis crebris obsitis ; pedicellis involucro angusto-turbinato (lineam 

 longo) 4-5-lobato 7— 9-floro aut pauUo aut inferioribus 2-4-plo longi- 

 oribus, fructifei'is s^epius dellexis ; bracteolis filiformibus subglanduloso- 

 ciliatis ; perigonii basi brevi obtusissimo, segmentis albis linea media 

 viridula, exterioribus subcordato-ovatis obtusissimis, interioribus multo 

 minoribus oblongo-ovatis acuminatis. — Southern Utah, Dr. Parry, 

 no. 239 (1874). A well-marked species of this group, with the foliage 

 of £. dejlexum, tlie involucres rather of E. Watsoni, but the stems from 

 the base of the scape up to the involucres beset with small stipitate 

 glands, of a character between those on the pedicels of E. nutans and 

 those on the whole panicle of E. glandulosum ; and in the structure of 

 the perigonium different from all of them. To be reached by the key 

 in the Rev. Eriog., a line should be inserted on p. 151, before line 20, 

 thus : Ilerbte annute, prajter folia tenuiter viscoso-glandulosae. 



Sciiipus (Eleocharis) Wolfii. Rhizomatibus tenerrimis rejDen- 

 tibus perennans, ca^spitibus .parvis sparsis ; culmo pedali gracili glau- 

 cescenti-pallido ancipiti hinc piano illinc convexo undique tenuiter 

 striato, vagina ore oblique truncate hyalino ; spica ovato-oblonga acuta ; 

 squamis oblongo-ovatis obtusis scariosis pallidis jiurpureo tinctis ; stylo 

 tripartito ; achenio pyriformi nitidulo suba^qualiter obtuse circiter 

 9-costato inter costas transverse lineato-ruguloso, tuberculo parvo 

 depresso truncato centro pi. m, apiculato ; setis perigynii (an semper ?) 

 nuUis. — Margin of ponds, in very wet soil, Fulton County, Illinois, 

 John Wolf. Probably it will jirove to be not uncommon. I have 

 specimens collected in the same region, doubtless at Athens, Illinois, in 

 the year 18G1, by Elihu Hall. Professor Wolf in a letter alludes to 

 six set* of the perigynium ; but I detect none whatever in the speci- 

 mens. The spike as to form and imbrication of the scales is much as 

 in S. tenuis and S. compressus, &c. ; but the achenium, with its several 

 longitudinal ribs and delicate transverse lineation, is upon the plan of 

 that of S. acicularis. This renders the species a very peculiar and 

 distinct one.
