Wahlenbergia grahamae. Hems!., n. sp. (Plate LYL, figs. 5, 10.) 



Species aff. Wahlenbergice fernandeziance a qua differt habitu robustiore foliis ovatis 

 vel leviter cordato-ovatis minute denticulatis puberulis, floribus majoribus, corollse lobis 

 latioribus, &e. 



Juan Fernandez. — Endemic. Mrs Graham, 1823; Moseley. 



Mrs Graham's specimen of this previously undescribed species of Wahlenbergia was on 

 a sheet with specimens of Wahlenbergia fernandeziana, from which it is easily distinguish- 

 able at a glance, as Miss Smith's drawing shows. Mr Moseley collected one sprig of the 

 same species, which is in no other collection that we have seen. 



Wahlenbergia tuberosa, Hook. f. 



Wahlenbergia tuberosa, Hook, f., Lot. Mag., t. 6155. 



Euphorbia maso/iienr, Philippi in Bot. Zeit., 1856, p. 647, et in Cat. PL Vase. Chil., p. 264. 



Masafuera. — Endemic. Leyboldt; Downton. 



It is remarkable that no other botanist or traveller who has investigated the flora 

 of the island has collected this very distinct species, which was discovered in 1873 by 

 Mr Downton, who introduced living plants for Messrs Veitch of Chelsea, where it flowered 

 in 1874. Probably the slender flowering stems are of short duration, and the tuberous 

 root-stock inconspicuous, hence the reason of its being overlooked. Leyboldt's specimen 

 wants flowers. 



Wahlenbergia berteroi, Hook, et Am.
