134 Flora of Giiadaltipe Island. [zoe 



Prof. Greene, but also in the dry bed of the canon 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 canon 

 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. Canon near the landing. (64.) 

 Lepigomivi vi aero the cunt F. & M. Seen only on a perpen- 

 dicular cliff" on the right bank of the canon, not far from the 

 landing; growing there in number. Specimens of a Silene — 

 dried stocks of the preceding j-ear were abundant near the 

 landing, (29.) 



Claytoiiia 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. (540 



SphcBvalcea sulphiwea Wats. Much more abundant than 

 Lavatera, one of the very few plants of which some meager 

 specimens maj^ 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-) 



Erodmni moschatum L'Her. Plentiful all over, chiefly 

 among rocks and stones; not so much so, however, as Er odium 

 cicutarium which now literally covers the whole surface of the 

 island. E. moschahim appears not to be liked by goats, at least 

 where other food is obtainable. (22.) 



Ceanothus crassifoliics Torr. Twelve to fifteen feet high. Only 

 one plant found alive near the centre of the island west of IMount 

 Augusta, among the cypresses, but surrounded by what appear
