its way into San Miguel. — E. mucronatus DC. is also naturalized 

 in many places, as at the Furnas. — E. linifolius Willd. Ponta 

 Delgada. 



Gnaphalium luteoalbumLi. and G-imrpureiim L. Ponta Delgada. 



Bidens inlosa L. Naturalized at Ponta Delgada, and likely, as 

 in Madeira, to become a pest. 



Petasites frag rails Presl. Near Ponta Delgada. 



Senecio malvcefolius DC. Rare ; on cliffs at Capellas. — 

 S. viikanioides Otto. This African species I saw on the site of 

 an old garden west of Ponta Delgada. It is quite naturalized in 

 Madeira. 



Urospermum picroides Schmidt. On waste ground at Ponta 

 Delgada ; Trelease says " not recently collected." 



Campanula Vidalii Watson. This very interesting and local 

 species was discovered by Captain Vidal, who picked it on an in- 

 sulated rock off the coast of Flores. Watson was unable to find 

 it on the mainland. Hunt, according to Watson, was afterwards 

 more successful in finding it locally on the coasts of Santa Maria 

 and San Miguel, whence its introduction to English gardens is 

 said to be due. Trelease, however, states that it " occurs on cliffs 

 and detritus by the sea-shore and on outlying rocks round the 

 entire island of Flores," and goes on to say that, as regards Santa 

 Maria and San Miguel, " the impression there and in Terceira is 

 that it occurs in cultivation only, and was originally derived from 

 Flores." It is therefore pleasing to be able to add a station where 

 it is indubitably native on San Miguel. This is at Capellas, a 

 fishing-town of about three thousand people, nearly nine miles 

 from Ponta Delgada. In the narrow bay is a considerable whale 

 fishery, which gives the town its prosperity. The bay is surrounded 

 on three sides by very steep cliffs, especially on the southern side. 

 In one a path has been cut in the solid lava, by which access is 

 given from the top to the sea-level. A wall protecting from the 

 sea is thus formed ; on this I climbed to see what vegetation grew 

 on the seaward side, where the cliff is vertical. - A plant, which 

 I took to be a Euplwrhia, grew temptingly out of reach, but I 

 managed to reach a few of the leaves and a flower-stalk of the 

 preceding year, and then recognized this extremely local species. 

 Dr. Carreiro has since seen the plant there, and I believe supports 

 my view of its being indigenous in a station where it is not likely 

 to be eradicated. The plant is full of an extremely viscid milky 

 juice, which can be drawn out in long threads. It grows well 

 from seed in England. 



Vaccmium cylindraceum Sm. Lameiro, &c. An endemic 

 species. 



Erica azorica Hochst. With other brushwood this species is 

 being rapidly destroyed, owing to the culture of pineapples. The 

 brushwood is cut into small pieces and spread about nine inches 

 thick in the glass-houses, then covered with some soil : into this 

 compost the pots of pineapples are placed, and the plants ripen 

 without other artificial heat than that induced by the fermentation 

 of this vegetable substance.
