umbel. In this specimen, the stem is apparently a scape, the flowers 

 are paler blue, smaller, more globose, and bracts colored. 

 A beautiful species, worthy of the attention of florists. 



August 2, 1858. 

 President in the Chair. 



Dr. Kellogg presented a specimen, accompanied by a drawing, of 

 what appears to be a new species of Calochortus. 



O. Ulacinus, (Kellogg) or Blue Beard Butterfly Tulip. — 

 Stem six to eight inches high, two-flowered, on long penduncles, (four 

 or five in.) flowers pale lilac, one to one and one-half inches diame- 

 ter ; petals (three) broadly cuneate, apex truncately rounded, erose- 

 dentate, inner surface bearded below the middle, nectariferous scale 

 ciUated along the margin, the claw below and laterally glabrous, 

 adorned with two bright purple spots about the size of a large pin's 

 head, one on each side of the nectar scale within, also a few purple 

 lines marking the base without; (three) petaloid sepals lanceolate, 

 membranous apex convolute-acuminate, revolute, color similar to petals, 

 but paler ; filaments colored, strongly recurved against the petals, di- 

 minishing from a broad base to a fine point ; anthers erect, looking 

 inwards, more than half the length of the filament ; pollen pale blue ; 

 capsule winged, ovoid ; leaves linear-lanceolate, or broadly linear, 

 twisted, erect, sheathing, two radical, bracts short linear acute. 



Flowers in May and June. Specimens from Napa Valley. The 

 first we saw was a monster of four petals, eight stamens, four stigmas, 

 and four cells, etc. The flowers invariably open in the morning 

 and close at four, p. m., whether indoors or out. AlUed to C. sjylen- 

 dens, but differs in general by its more diminutive size, truncate erose 

 petals, nectar scale and variegations, and above all the winged ovoid 

 capsule, which forms so close a connecting link with the genus Ci/do- 

 hothra ; in fact, the plant in general more nearly resembles this latter 



genus. 



The following new species of Campanula was also presented, with 

 the description. The specimen was presented before the Society July 

 16th, 1855, but the description delayed for lack of the lower leaves : 



C. filiflora, (Kellogg) or Tubular Bellwort. — Stem about a 

 foot in height, pentangular, with intermediate nerves or slighter ridges, 

 angles minutely scabrous, alternate leaves small, less than one inch on 

 very small petioles, ovate-lanceolate, acute or acuminate ; apex entire, 

 mucronate-dentate below, scabrous throuffhout.
