﻿114 PLANTS FENDLERIAN.E. 



cially in M. Californica, namely, that two (opposite) bristles of the pappus are naked 

 instead of barbellate, and rather stronger and less deciduous than the others. 



• 454. Crepis ambigua (sp. nov. non Balb.) : eaule scapiformi e radice perenni sim- 

 plici basi folioso apice racemoso-5-8-cephalis foliisque obovati-oblongis integerrimis setis 

 patentibus sparsis hispidis cseterum glaberrimis; capitulis majusculis longiuscule peduncu- 

 latis circa 30-floris ; involucro cylindrico hirto, squamis linearibus, extimis duplo breviori- 

 bus appressis ; ligulis (flavis ?) genitalia haud superantibus ; acheniis fusiformibus superne 

 sensim angustatis multicostatis glaberrimis pappum albidum longitudine sequantibus. — 

 Level, grassy places along Santa Fe Creek ; June to Aug. — A foot high, from a thick 

 perennial root, which yields a white juice ; the purplish stem leafy only near the base, 

 above nearly smooth and bearing one or two linear bracts. Leaves 2 or 3 inches long, 

 sessile ; the radical with a tapering base, hispid with slender bristles above, purplish under- 

 neath, resembling those of Hieracium Gronovii, /3. subnudum. Heads two thirds of an 

 inch in length. Ligules very short, little longer than the pappus, usually shorter than 

 the styles. Mature achenia blackish, a third of an inch long, attenuated upwards, but 

 not truly rostrate. Pappus copious, dull white, of bristles nearly as stiff as those of 

 Hieracium, but occupying much more than one series; — on which account I refer the 

 plant to Crepis (although the pappus is not bright white) rather than to Hieracium. 



* 455. Macrorhynchus purpureus (sp. nov.): perennis ; foliis e caudice crasso 

 rosulatis linearibus integerrimis vel plerisque pinnati-3-7-lobatis acutis crassiusculis sub- 

 glaucis glaberrimis; scapo aphyllo (6-8-pollicari) juniore floccoso-pubescente sub ca- 

 pitulo lanoso ; involucri glabrati squamis 3-seriatis appressis purpureo pictis obtusiusculis, 

 intimis linearibus extimas oblongas duplo superantibus ; floribus (in sice.) purpureis bre- 

 viter ligulatis : acheniis lineari-fusiformibus sequaliter 10-costatis glaberrimis in rostrum 

 scabridum iisdem pappoque paulo brevius attenuatis. — Grassy places, bottom of Santa 

 Fe Creek ; July. — Plant with the thick caudex and the aspect of a Troximon ; but 

 most of the densely clustered leaves (two or three inches long) bear a few short linear 

 lobes about the middle. Scapes at length glabrous. Heads cylindraceous, two thirds 

 of an inch long ; the scales of the involucre mottled or spotted, or the broader exterior 

 ones entirely painted, except the margins, with deep purple. Flowers purple ; the ligule 



viridi scariosis late ovalibus obtusissimis, intimis lanceolatis acutis. — California, Coulter. — A foot high, 

 stout ; the root unknown. Leaves 2 inches long. Heads 10 lines in diameter. Flowers, ovaries, and pappus 

 as in Malacothrix; but the scarious involucre is very remarkable. The fruit is unknown. 



Remarkably large specimens of Malacothrix Californica, with coarser foliage, and the head, including the 

 expanded rays, two inches in diameter, were collected by Dr. Gambell at Pueblo de los Angelos and distributed 

 under the name of " Macrorhynchus laciniatus."
