142 ERYTHEA. 



part of the island, this side of "The Isthmus," as we say, while beyond 

 "The Isthmus" it is here, there and everywhere — a veritable Lyono- 

 thamnus land. This "rare" tree blooms in June. In only two 

 groves I have found divided leaves; yet a tendency toward divided 

 leaves and imperfectly divided leaves is everywhere present; indeed, 

 in most groves the exception is the entire leaf The flowers are 

 white and the clusters are very showy. The groves stand on steep 

 slopes among great rocks. The finest specimens are over foi'ty feet 

 high, straight and slender, branching near the top, the first limbs 

 having apparently died away. The bark hangs in long shreds. 

 There are groves on slopes 500 or 600 feet above sea-level; several 

 are also found at about 2,000 feet elevation, on one of our 

 highest peaks, just above one of the old craters, the only green 

 which touches this desolate height. 



A single specimen of Marrubrium vulgare was collected at 

 Avalon last summer by Dr. Bishop. Alyssum maritiraum was also 

 found on a clifF-edge. 



Gymnogramme triangularis is found not infrequently, but the 

 var. viscosa is on all moist slopes and in every canon, together with 

 Adiantum emarginatum. Polypodium Scouleri is not abundant as 

 is P. Californicuai. Cheilanthes Californica and Aspidium rigidura 

 (or A, aculeatum) are fairly represented on moist slopes and in the 

 canon?, while fine specimens of Pellsea Andromediefolia are hidden 

 away in "the bushes" on the open ridges and Pellsea Ornithopus 

 abounds among all the cacti. Here also are the white flowers of 

 Convolvulus occidentalis. 



Fine specimens of a Delphinum are found on dry hills in March, 

 with the bright Erythrsea venusta at its feet. 



In Avalon Canon, Eulobis Californicus was found in one locality^ 

 with a "decidedly woody base;" in the same locality was Antirrhinum 

 strictura with woody base, one-half inch in diameter; the plants 

 were about three feet high. 



On arid heights Gilia dianthoides flowers profusely; a stem 

 scarcely rising out of the ground, will bear half a dozen blooms — 

 large, white, and fragrant. 



The violet-blue flowers of Nemophila aurita are seen on nearly 

 all canon sides. N. insignis thrives in one locality. 



A species of Nicotiana was discovered on Fisherman's Beach
