BuRRiELiA GRACILIS, BG. Prodr. 5,^. 664. Californiaj near Monterey, etc.; May; fo abundant 

 as to give a yellow appearance to the hills ; Parry. Mostly rather large forms. In one specimen 

 a slight disposition to have lobes to the leaves appears. 



BuRRiELTA CURYSOSTOMA, Torr. db Gray. FL 2, ^9. 3T9. Hill sides, common From Monterey to 

 San Diego, California. The specimens occur mixed with the preceding, from the larger forms 



of which they are externally undistinguishable. Unless the more obtuse receptacle affords a 

 character, ii will probably come to be regarded as only an epappose state of B. gracilis. 



BuRRiELiA PLATYCARPHA (sp. nov.) : er< cta, spitham^a, subramosa, laxe pubcscens ; foliis sa3- 

 pissime trifidis segmentisq^ue filiformi-linearibus ; pedunculis sursum incras^atis ; involucri 

 multifiori squamis ovatis trinerviis ligulisque oblongo-linearibus stepius 7 ; coroHa imberbi ; 

 pappo conform! e paleis 7-8 oblongo-ovatis aristatis achenio a^quilongis ; receptaculo acute 

 conico. — Valley of the upper Sacramento ; Br. Snllman. This is a genuine Burrielia, having the 



pale;i3 of the pappus all alike and awned. The scales of the involucre (fully 4 lines long) and 

 theligules are considerably larger than those of the largest states of B. gracilis and B. (Bueria) 

 chrysostoma, although fewer. It is related on the one hand to B, gracilis, from which it is a 

 once distinguished by its lobed leaves, stouter peduncles, more upright habit, fewer rays and 

 involucral scales, the latter much broader as well as larger, 3-nerved and more pointed, and by 

 the equally larger and broader as well as more numerous paleae of the pappus ; on the other to 

 B. (Dicha^ta) Fremontii, which has much smaller heads, a dimorphous pappus of much smaller 

 pale?e, etc."^ 



Burrielia (Ptilomeris) anthemoides. Ptilomeris antheraoides^ Nutt. in Trans. Amer. Phil.

A, 



Capitulum homogamum multiflorum ; floribus hermaphroditis tubulosis. Involucrura circiter 

 10-phyllum, biseriale ; squamis fequalibus membranaceis, interioribus glandula apiculatis. 

 Receptaculum nudum, scrobiculatum. Corolla cylindrica; tubo proprio brevi angusto, dentibus 

 5 patentibus ovatis. Anther<ne ecaudate. Styli rami compressi, glaberrimi, apice tantum capi- 

 tellato-truncato brevissirae hirtelli. Achenia immatura oblonga, basi angustata, hirsutissiraa. 

 Pappus corolla brevier, e paleis 5 hyalinis enerviis oblongo-lanceolatis in setas plurimas rigidas 

 profunde fissis. Herba nana, hyemo-annua vel biennis, dicliotoma, humifusa, floccoso-lanata, 

 subglandulosa ; foliis alternis cuneato-oblongis argute inciso-dentatis lobatisve, dentibus cuspi- 

 dato-acuminatis ; pedunculis terminalibus et alaribus filiformibus monocephalis ; corollis ochro- 

 leucis?

montii ; Ltit all the specimens in my set are entirely destitute of pappus, which could not have been the case in those whicli 

 Mr. Bentham examined. Since the two plants apparently agree in all other particulars, it is most likely that my specimens 

 belong to an epappose state of the species ; just as all Nuttall's species of Ptilomeris are probably forms of one. At any 

 rate, it is now certain that Ptilomeris and Dicha^ta, as well as Baeria, must be reduced to sections of Burrielia.
