PITTONIA. 



as good were collected by his brotlier, Joseph Howell, near 

 Woodville, in 1888, and on Coquell Kiver early this year. 

 The species is so much like S. occidenialis in foliage," size 

 and general aspect, that it will easily be confounded with it 

 if one overlook the clavate filaments and the unguiculate 

 yellow-dotted petals. 



Saxifraga Califoknia, Greene, I. c. 256. Common in both 

 ranges of mountains throughout the entire length of Califor- 

 nia ; Mr. Joseph Howell now sends it from near Eoseburg, 

 m Southern Oregon. It, is very readily distinguished from 

 both those above mentioned, and also from S. rejlcxa to which 

 Dr. Gray at last referred it, by the strongly developed perig- 

 ynous disk by which the ovary in the flower is made to appear 

 very broad and flat-topped. 



Gayophytum lasiospeemum. Very slender, erect, 1 or 2 

 feet high, simple below, parted above into numerous diclio- 

 tomous somewhat flexuous branches ; glabrous except a scant 

 pubescence on the flower-buds : leaves narrowly linear, f to 1 

 inch long : corolla 1|- lines broad, rose-color changing to rose- 

 purplish : capsules linear-oblong, on capillary erect pedicels, 

 fevy-seeded, torulose : seeds canescent with an appressed 

 silky pubescence. 



Near Julian, San Diego Co., California, Aug. 1SS8. 



Choeizantiie Noetoni. Erect, a foot high or less, simple 

 below, tri- and dichotomously corymbose at summit ; canes- 

 ceutly soft-pubescent : leaves in 1 to 3 whorls, narrowly 

 oblanceolate, 1 to 2 inches long ; bracts narrowly lanceolate, 

 cuspidate : involucres solitary in the earliest forks, but at 

 the ends of the branches disposed in large dense capitate 

 clusters ; tube triquetrous, with 3 intervening ribs ; limb dila- 

 ted and tnanguLir, the three broad equal rose-purple seg- 

 ments acute or acuminate, ending in a short uncinate awn : 

 perianths 2 or more, pinkish changing to rose-red ; segments 

 oblong, obtuse, very unequal : stamens exserted.
