PLANTS FROM BAJA CALIFORNIA. 175 



ciliate and somewhat saccate at the tip; palete of the recep- 

 tacle acute enfolding the disk-akenes, the center of the head 

 occupied bj a hispid awn which is evidently an abortive 

 scale: flowers yellow, 4 or 5 in a head; rays 1 or 2, broadly- 

 oval, 5-6 mm. long, irregularly 1-6 notched; akenes effete 

 obscurely triangular, very slenderly linear, with a pappus 

 of 3-5 lanceolate paleae: flowers of the disk 2 or 3, tubular; 

 tube pubescent; akenes clavate-oblong, quadrangular, trun- 

 cate, pubescent above, shorter than the ray-akenes; pappus 

 of 2-4 lanceolate, hispid, paleaceous awns from the angles 

 of and about as long as the akene, and 6-12 intermediate, 

 shorter and similar, all easily deciduous. — Not uncommon 

 on the elevated mesas about Purisima and Comondu. 



The small heads of this peculiar plant are so closely ap- 

 proximated that the outside bracts of those on the circum- 

 ference frequently simulate an involucre subtending the 

 glomerule, but careful inspection alwaj^s shows that they 

 are on different planes. 



Encelia ventorum. Perennial, glabrous, much branched 

 from the base, 3-4 feet high, 2-3 inches thick; branches 

 and leaves succulent: leaves crowTled at the ends of the 

 branches, linear, 2 mm. wide, 2-3 inches long, with 3-4 

 linear, sometimes dentate lobes from the upper half: heads 

 . numerous, fragrant, with rather small and inconspicuous rays 

 half hidden by the clustered leaves: scales of the involucre 

 ovate-acuminate: palese of the receptacle truncate, thick- 

 ened and pubescent at tip: tube of the neutral ray hirsute 

 and nearly as long as the ligule: style branches acute: an- 

 ther tips obtuse: akenes awnless, hardly auriculate, margins 

 long-villous. — Common on th^ narrow strip of sand between 

 the lagoons and the ocean near the Boca de Las Animas. 



Encelia laciniata Vasey & Kose. With ciliate involucral 

 scales. — San Gregorio. 



Encelia Californica Nutt. — Socorro.
