19-1 PROCEEDINGS OP THE AMERICAN ACADEMY 



long-petiolate, oblong to narrowly oblanceolate, thin, slightly crenate ; 

 the°cauline few, sessile, linear-lanceolate, acutely or spinosely toothed: 

 head oblong-ovate (about 6 lines long), shorter than the 10 or 12 

 linear-lanceolate bracts, which are white above and green beneath, 

 with a single spinose tooth on one or both sides ; head crowned with 

 3 or 4 similar bracts ; floral bracts very narrow and spinosely acu- 



jjjjjjate. At Cieneo-a in the Huachuca Mountains, Southern Arizona, 



growing in water; J. G. Lemmon, September, 1882. Allied to 

 E. Mettaueri, Wood. 



Su.EDA MiNUTiFLORA. Perennial (?), glabrous, the herbaceous 

 stems erect, 2 feet high, the branches mostly short and suberect : 

 leaves linear, not narrowed at base, 1 or 2 inches long, the upper 

 broader and clasping at base ; flo ,ver-bracts lanceolate to deltoid : in- 

 florescence mostly crowded, the very small flowers clustered in the 

 axils; perianth mostly scarious, not appendaged : seed less than half a 

 line broad. — At Santa Barbara, abundant in a marsh near the sea, 

 first collected by Mrs. Elwood Cooper, in 1879 ; also at Los Angeles, 

 by Rev. J. C. Nevin, 1882. 



EiuoGONUii Shockleyi. Closely allied to E. Kingii, dwarf and 

 very densely cespitose, densely tomentose throughout : leaves oblan- 

 ceolate and petiolate, 6 lines long or less : scapes less than an inch 

 hio-h : heads globose, compact ; involucres tomentose, scarious at base, 

 the lobes herbaceous : flowers included, rounded at base, pubescent or 

 nearly glabrous below, villous within, the narrowly oblong segments 

 white with a green midvein ; filaments and elongated styles exserted. 

 — At Candelaria, Esmeralda County, Nevada, on bare rocks at 6,500 

 feet altitude; discovered by W. H. Shockley, June, 1882. Differing 

 from E. Kingii in its shorter peduncles, more compact globose heads, 

 smaller included flowers, narrower perianth-segments, more elongated 

 styles, and less sharply angled akenes. 



Eriogonum Havardi. Perennial, with a very short branching 

 caudex : leaves all at the base, oblong-lanceolate, acute or acuminate, 

 petiolate, densely tomentose beneath and silky above, 1 to H inches 

 long : peduncles slender, 1 or 2 feet high, glabrous, sparingly dichoto- 

 mous above ; bracts small and ternate : involucres solitary, long-pedi- 

 cellate, or sessile at the forks, broadly turbinate and nerved, with 

 short erect teeth, somewhat pubescent or glabrate, a line long or more : 

 perianth densely silky, with narrow acute lanceolate segments, a line 

 long, yellowish : akene glabrous, ovate, acuminate, a line long. — Col- 

 lected in the Chenati Mountains, Western Texas, by Dr. V. Havard, 

 U. S. A., 1882. An anomalous species, i*esembling E. lachnogynum,
