134 Flora of Guadalupe Island. [zoE 
Prof. Greene, but also in the dry bed of the cafion and on the bare 
‘dry rock at the mouth of it, and a single specimen found on the 
ridge of the lower crater about the centre of the island east of Mt. 
Augusta. All these plants appear to be annual, but apparently 
the same species grows luxuriantly as a perennial on a nearly 
inaccessible cliff of lava detritus on the right bank of the cafion 
500 or 600 feet from the landing. These plants were already in 
flower at the beginning of January. The flowers have no green- 
ish tinge at all; petals not over two-thirds of an inch long. (20.) 
Oligomeris subulata Boiss. Cafion near the landing. (64.) 
Lepigonum macrothecum F. & M. Seen only on a perpen- 
dicular cliff on the right bank of the cafion, not far from the 
landing; growing there in number. Specimens of a Silene— 
dried stocks of the preceding year were abundant near the 
landing. (29.) 
* Claytonia perfoliata Donn. Quite common from centre to 
north, most luxuriant under the palms where it was in flower 
early in December. (53.) 
Lavatera occidentalis Wats. A few scattered specimens, all 
on the most inaccessible rocks east of the island. A few seed- 
lings not likely to survive found in several localities. (12.) 
Malva borealis Wallm. Now a common weed; apparently 
not liked by the goats. (54.) 
Spheralcea sulphurea Wats. Much more abundant than 
Lavatera, one of the very few plants of which some meager 
specimens may be seen scattered about even in places occasion- 
ally visited by goats. Seedlings and young plants observed near 
the landing both on the beach and on the dry lava rock. (13.) 
Evodium moschatum 1?Her. Plentiful all over, chiefly 
among rocks and stones; not so much so, however, as Evodium 
cicuiarium which now literally covers the whole surface of the 
island. £. moschatum appears not, to be liked by goats, at least 
where other food is obtainable. (22.) 
Ceanothus crassifolius Torr. Twelve to fifteen feet high. Only 
one plant found alive near the centre of the island west of Mount 
Augusta, among the cypresses, but surrounded by what appear
