168 PROCEEDINGS OP THE ACADEMY OF 



The Rcknowledgpd error of Lindley, Kunth, &c., of referring the original species of 

 Pursh {('. ekffans, A.D. 1816) to a genus invented ten years later {Cydoholhra, Sweet, IS26), is 

 avoided by including both genera in one, under Pursh's name. Moreover, Sweet's genus 

 cannot possibly be distinguished by "fovea nectarifera alte impressa" (the only distinc- 

 tion relied upon), for in C. elegans and its congeners " the pit" fades away by degrees, be- 

 coming imperceptible. If, however, the two genera be insisted on. Sweet's name must 

 give place to the prior one of Pursh, and a new name (none more appropriate than Mari- 

 posa) oonftiTredinp\aoe ot the Cahchrn-tus of Lindley, Ac. No one acquainted with these 

 beautiful flowers will regret the disuse of so distasiefnl a name as CydubMira. 



\Calochortidea, Petals impressed inside with a nectariferous pit, wliich is 

 gibbous outside, beard scattered, soft, margin ciliate-fringed.

 C. PULCHELLUS. Erect, branched above ; flowers globous, yellow ; the upper

C. ALBUS Dougl. Erect or inclined, branching; flowers oblong, inflated, 

 white, the upper in pairs, with lanceolate acuminate bracts ; sepals oval, much 

 shorter than the concave, scarcelj' fringed petals ; anthers obtuse ; ovary obo- 

 void. — California, common in all the foot hills. 1 — 2 f. Leaves and bracts

 whiteness. May, June. (Cyclobothra albu Benth., 1. c. G. alba and paniculata

** Perianth expanding, nodding (not pendulous). 



C. ELEGANS Pursh. Stem slender, with one radical, linear leaf; flowers in 

 pairs or threes, open, nodding or suberect, white or purplish ; sepals oblong, 

 cuspidate, greenish-purple, the petals much larger, roundish-obovate, soft-

i'/?^ Mariposa. Periasth erect, open. Sepals convolute-acuminate. Petals 



plane, erect-spreading, often spotted, but with no nectariferous pit. Seeds oval, 



compressed. (Vide G. venustus, below.)

 oval, obtuse, nodding 

 C. UMBELLATUS (n. sp.) FoUo radicali unico, lineari, caulera et bracteas 

 foliosas longe excedente; floribus 5 — 9, fere umbellatis, erectis ; pediculis 

 subradicalibus, longissirais, ebracteatis, fructiferis recurvatis ; petalis flabelli- 

 formibus, apice rotundatis, erosis, glaberrimis, basi squama ciliata instructis,

 Folium pedale. Petala 10 lin. Maia. [Cyclobothra elegans, ya,r. Torr.l R. R. 

 Rep. iv ) Distinguished from G. elegans by its many flowers, beardless petals, 

 entire absence of nectary, &c.
