This handsome shrub belongs to the section to which the 

 generic names Thurherm and Ingenhouzia have been given. 

 The specimens were in flower and lacked mature fruit, 

 but fortunately some old empty capsules were yet persistent. 

 It was seen only upon Santa Margarita Island where it is 

 very common, often growing in masses. Named for Dr. H. 

 W. Harkness, President of the California Academy of Sci- 

 ences, as a tribute to his efforts in furthering the explora- 

 tion of Lower California. 



Ayenia Berlandieri Watson. — Comondu. 



Ayenia pusilla L. Specimens not so strict as those from 

 Sonora, smoother and with more ovate leaves. — Magdalena

Galphimia angustifolia Benth. var. oblongifolium Gray.

VisCAiNOA GENICULATA (Kell). These specimens, differ- 

 ing considerably from previous collections, show the species 

 to be very variable, and bring it even closer to Cliitonia 

 than had been previously supposed. The leaves are either 

 simple or imparipinnate, with 3-5 leaflets: petioles often 

 more than a half-inch in length : flowers ochroleucous. 

 Abundant in some places, and called by the inhabitants, 

 who have a very good idea of its botanical affinities, "guia- 

 can." — San Eaimundo, San Fernando. 



Fagonia Californica Benth. Leaflets sometimes an inch 

 long, larger than those of Californian specimens.
