﻿PLANTS PRATTENIANiE CALIFORNIA. 101 



globosa, multifloraj; involucrum maximum, campanulatum, lanugine densa tectum, 

 brevi-dentatum ; perianthiis exertis, glabris, purpureis ? in sicco ochroleucis. 



Mr. Pratten collected only two specimens, one without, the other with a verticil of 

 four small, oval and shortly-petioled leaves a little above the base of the glabrous scape ; 

 umbel terminal, globose, very crowded; involucre large, very lanuginous, with short 

 oval-acute teeth ; perianths exserted, glabrous, probably purplish, but yellow in the 

 dry state. Radical leaves wanting.

ORCHIDACE^]. 



GYMNADENIA longispica, sp. nova, (specimen cui folia radicalia desunt. ) Scapo 

 gracili, erecto, fere pedali; foliis 4 infra spicam, parvulis, bracteiformibus, ovato-lanceo- 

 latis ; spica circiter 50-flora, gradatim ad apicem gracilescenti, 7" longa ; bracteis lan- 

 ceolatis, ovaria gequantibus ; floribus minimis, albis? in sicco fuscantibus ; corollis 

 cernuis, sepalis subaequantibus, labio integro, calcare tenui, clavato, ovario longiori. 



The spike is very long, tapering, with at least fifty flowers. Sepals and petals 

 almost equal, lip entire, spur longer than the germ, filiform, clubshape, with a much 

 longer spike than Spiranthes bracteosa of Lindl. in Bot. Reg. T. 1934, to which Gytn- 

 nadenia longispica has a great resemblance. The inflorescence seems spirally twisted 

 round the scape.

FRITILLARIA lanceolata, Pursh. Fl. Am. vol. i. p. 230. Mr. Pratten's speci- 

 mens are, evidently, the same as Pursh's plant, although bearing from 2 — 4 flowers. 

 One specimen with a whorl of 3 leaves at the base is 14" long and has 4 flowers. 

 The whole plant is slightly pubescent ; the leaves are linear-lanceolate, parallel-veined, 

 those of the whorl about 4" long. Between the whorl and flowers the scape is naked ; 

 but each flower is in the axil of a leaf longer than the recurved peduncle. Flowers 

 campanulate, purplish, with darker spots, more than one inch diameter at top ; petals 

 narrow-lanceolate, longer than the stamina. Pistil and ovary minutely hispid. In 

 wet places around Nevada. May.
