 Greene), of more northern range; the sontheru form passes into the type.

Viguiera tomentosa Gray. Proc. Ainer. Acad. V. 161. This is a very rare species 

 in herbaria and is only linown before from the collection of Xantiis (1859-60), 

 from the vicinity of Cape St. Lucas. An upright growing plant with several 

 woody stems. It has a large, loosely hanging top ; a very free bloomer. Com- 

 mon on arroyos and on uiesas. No. 83. 



Encelia Palmeri Vasey & Rose. Proc. Nat. Mns. IX. 5^5. These specimens have 

 somewhat smaller leaves, either cordate or cuueate at base; the akenes obo- 

 vate. Dr. Palmer says it ia a very common plant nere. It is '^ feet high, in 

 compact masses, and is a very showy plant. It has been collected by Mr. 

 Braudegee at Magdalena Island and San Grogorla. No. 15. 



Encelia farinosa Gray. Only a single plant collected. It is called " Incienso," be- 

 cause of the gum which the woody part yields being used by the priests in 

 early times for incenne. It is amber-colored and has a pleasant aroma. Not 

 before collected so far south. Mr. Brandegee has referred here his E. radians. 

 No. 50. 



Bidens Xantiaiia Kose, n. sp. Stems terete, a foot to 15 inches high, slender and 

 somewhat spreading at base, glabrous throughout: leaves much shorter than 

 iuternodes, opposite, bipiunate with short linear segments: head on* long 

 peduncles: the outer involucre of short linear bracts, the inner longer, ovate 

 and acute: disk about 3 lines high; rays 8, about 5 lines long, styliferous: 

 akenes 2-awned.— We name this species for Xantus, who collected here in 

 1859-60. It seems nearest B. arKjuHlissima H. B. K., bnt differs in its terete 

 stem, shorter leaflets, and glabrous involucre. It differs from most liidens in its 

 styliferous rays. Only a single plant seen; this grew in a shady arroyo. No. 5. 



Leptosyne parthenioides, var. dissecta Watson. Proc. Ainer. Acad. XXIV. 56. 

 Very similar in habit to this form. It is L. heterocarpha Gray, and if this spe- 

 cies is not to be kept distinct, as ia held by Mr. Watson and Mr. Brandegee, it 

 should be referred to this variety and not to the species proper, where it is 

 assigned by these authors. The akenes are smaller than in the species proper; 

 the dissected wings thick and corky, and the awn retrorsely hispid ; this was 

 noticed by Mr. Brandegee, but in Bentham's figure (Bot. Sulphurt. 16) they are 

 upwardly hispid. No. 62 of Xantus. Found in only a few places in the shade 

 of trees. No. 19.

Dysodia speciosa Gray. Proc. Amer. Acad. V. 163. Rather plentiful, growing near

 only known before from Palmer's 1887 collection from Guaymas, Mexico. No.
