PLANTE FENDLERIANE. ot 103 
species between the Wallamet River and California; and a low form, with the heads even 
smaller than in Fendler’s plant, exists in Fremont’s third collection, apparently from the 
interior of the south part of Oregon.— Mr. Fendler gathered a monstrous state of this ° 
species, with the flowers of the head all pedicellate, so as to form an umbel, the pappus 
transformed more or less into bract-like lobes, the corolla prolonged and more herbaceous, 
the anthers distinct, &c. 
fe 
squamis totidem parvis truncatis 2—3-fidis alternantibus. — California, Fremont (1846). — Heads as large as 
those of Burrielia gracilis; the branches of the style tipped with a similar capitate cone ; while in B. micro- 
glossa and B. gracilis the appendage is more slender. ts 
A more striking case of diversity in the pappus of plants which are otherwise almost undistinguishable 
occurs in Layia, Hook. §& Arn. (Madaroglossa, DC.; Eriopappus, Arn.), Callichroa, Fisch. §- Mey., Calliglossa, 
Hook. § Arn., and Calliachyris, Torr. § Gray, which it is becoming evident should all be viewed as sections 
merely of a single genus, to which perhaps even Oxyura, with no pappus at all, will ultimately be added. 
Thus combined, the sections of the genus would be characterized thus : —

, § 1. MADAROGLOSSA, DC, (Eriopappus, Arn.) Pappi ariste setiformes, basin versus pilis tenuissimis 
prelongis lanato-plumosz seu villose: receptaculum inter flores radii et disci tantum paleaceum. z 
Lavi sp., Torr. & Gray, Fl. 2. p. 393, excl. no. 1.— L. elegans, which has been gathered by Coulter, 
Fremont, Hartweg, &c., occasionally is destitute of the crisped and interlaced wool of the inside of the pap- 
pus, which is then consequently less villous than in the other species, and connects this typical group with 
the third section. 
§ 2. LAYIA, Hook. §& Arn. Pappus ut in § 1: receptaculum inter flores disci exteriores paleaceum. 
L. Gartnarproiwes, Hook. § Arn. l.c. I have seen this species only in a collection made in California 
by some Russian botanist.

radii et disci tantum paleaceum.

the achenium, though longer) are similar to the more abundant ones of L. heterotricha.
