162 PROCEEDINGS OP THE AMERICAN ACADEMY 



The entire plia^nogamous flora native to the island, as given by Mr. 

 Hemsley, includes but twelve species, and ten of these are marked 

 by him as only doubtfully indigenous. The two other species, Hed- 

 yotis Adscensionis and Euphorbia origanoides, are endemic. The 

 cryptogamous flora is somewhat more extensive, the same authority 

 giving a list of fourteen ferns (including a Lycopodium), thirty-five 

 mosses and hepatics, and a dozen lichens. 



The following is a list of the species of every kind collected by 

 Mr. Loomis, of which those in italics are without doubt introduced 

 plants. The species of ferns described as new have been submitted 

 to Prof. Eaton and to Mr. J. G. Baker. The mosses were determined 

 by Prof. C. R. Barnes, the single hepatic by Prof. L. M. Underwood, 

 and the lichens by Prof. Farlow. It is to be regretted that the oppor- 

 tunity could not have been improved to make a larger and more 

 complete collection of the plants of the island, for it is probable that 

 a thorough search would increase considerably the number of indige- 

 nous species now known. 



Argemone Mexicana, L. Abundant. 



Senebiera didyma, Pers. 



Oxalis corniculata, L. 



RuBUS NANUS. Stems very short (1 or 2 inches high), from a 

 woody caudex, erect, armed with numerous short recurved prickles, 

 about 3-flowered at the summit: stipules narrow, acuminate, entire or 

 sparsely toothed ; petioles short, pubescent and prickly ; leaves mostly 

 simple and rounded, snbcordate at base, unequally and subincisely ser- 

 rate, somewhat .'3-lobed or sometimes ternate, sparsely villous above, 

 prickly on the veins beneath: calyx small (about 4 lines broad), the 

 base prickly : carpels rather numerous, on a depressed receptacle, gla- 

 brous ; styles short. — Described from a single specimen found near 

 the entrance of a tunnel in Elliott's Pass. It appears to be a very 

 distinct and peculiar species of a genus not otherwise represented in 

 the flora of the islands of the South Atlantic.
