foliaceous bracts subglabrate above : the broad inflorescence several 

 times di- or trichotomous upon naked peduncles ; pedicels mostly elon- 

 gated and naked; involucres at first nodding, campanulate (1^ to 2 

 lines long), the deltoid teeth erect : flowers very small, densely tomen- 

 tose, slightly exserted. — Near Waldo, southern Oregon ( T. Howell, 

 July, 1887). 



Eriogonum (§ Virgata) cithar^eforme. Annual, prostrate or 

 procumbent, branching from the base, mostly' glabrous excepting the 

 floccose-woolly lower surface of the leaves ; stems a foot high or less, 

 several times 2-3-plurichotomous, the lower bracts foliaceous, the 

 upper small and triangular : lower leaves 4 inches long or less, undu- 

 late, dilated and 3-5-nerved at the summit, the rounded blade abruptly 

 contracted into the long winged petiole : involucres glabrous, broadly 

 turbinate, with broad teeth, 1 to \\ lines long; flowers rose-color, a 

 line long, the segments spatulate-obovate. — Nearest to E. gracile. 

 Found by J. G. Lemrnon (n. 1584) on Baron Schroeder's ranch, 30 

 miles north of San Luis Obispo, in June, 1887. 



Tillandsia (Diaphoranthema) Wilsoni. Stem simple, very 

 short (about \ inch): leaves numerous, 1 to 3 or 4 inches long, grad- 

 ually narrowed from the clasping base to the long-attenuate apex, 

 channelled above, more or less hoary with minute appressed peltate 

 brown-centred scales : peduncle very slender, recurved, about equal- 

 ling the leaves, with 2 distinct bracts, probably 1-3 -flowered: flowers 

 and capsules not seen. — Abundant upon dead branches of the red 

 cedar in a hummock skirting the Pithlachascotee River in Hernando 

 County, Florida, about two miles above its mouth, where it was 

 discovered, in 1887, by Dr. W. P. Wilson, of the University of 

 Pennsylvania. It is in cultivation at Cambridge, but has not yet 

 flowered ; very distinct from all our other species. 



Brodi^ea Hendersoni. Closely related to B. Bridgesii: scape 

 and leaves about a foot high, the leaves 3 to 5 lines broad : pedicels 

 about an inch long : corolla salmon-color with often broad brown- 

 purple nerves, 6 to 12 lines long, the narrowly turbinate tube shorter 

 than or barely equalling the limb : stamens in one row at the throat, 

 the slender equal filaments scarcely or but slightly broader near the 

 insertion, somewhat wing-dilated below within the tube ; anthers very 

 short : capsule ovate, shorter than the stipe. — Near Ashland, Jackson 

 County, Oregon (L. F. Henderson, July, 1884 and 1886). 



Calochortus (Mariposa) Howellii. Of the C. nitidus group; 

 stem erect, a foot high or more, 1-2-flowered : leaves very narrow, 

 the cauline (one and a floral pair) short ; sepals ovate, shortly acumi-
