REPORT ON THE BOTANY OF JUAN FERNANDEZ AND MASAFUERA. 69 



Hymenophyllum tortuosum, Hook, and Grev. 



HymenopyUum tortuosum, Hook, and Grev., Ic. FiL, t. 129; Hook., Sp. Fil., i. p. 99 (excl. syn. 

 Hijmenoplujlhaii nigricans, Colla) ; Hook, and Bak., Synopsis FiL, p. 70. 



Juan Fernandez. Reed; Philippi; Downton. 

 A common species in extratropical South America. 



Hymenophyllum tunbridgense, Smith. 



Hymenophyllum tunbridgense, Smith, Fl. Brit., p. 1141 ; Hook., Sp. Fil., i. p. 95; Hook, and Bak., 

 Synopsis FiL, p. 67; Gay, Fl. Chil., vi. p. 530; Philippi in Bot. Zeit., 1856, p. 631. 



Juan Fernandez. Gay; Philippi. 



There are no Juan Fernandez specimens of this fern in Kew Herbarium, but as it is 

 the most universally dispersed species of the genus, it is not unlikely to occur. The form 

 having entire involucral valves (j3 wilsoni, Hook, and Bak.) is common in Chili. 



Trichomanes dichotomum, Philippi. 



Trkhomanes dichotomum, Philippi in Bot. Zeit., 1856, p. 650. 



Juan Fernandez. Philippi. 



In the collection of Chilian and Juan Fernandez plants in the Kew Herbarium, pur- 

 chased by Mr Reed in 1873, there is a specimen of this fern labelled " Valdivia," in the 

 handwriting apparently of Philippi, though in the place cited the latter records it from 

 Juan Fernandez, therefore its native country is a little uncertain. 



Trichomanes exsectum, Kunze, 



Trichomanes exsectum, Kunze, Anal. Pteridogr., p. 47, t. 29, fig. 2 ; Hook., Sp. Fil., i. p. 141 ; Hook. 



and Bak., Synopsis FiL, p. 85 ; Gay, Fl. Chil., vi. p. 537 (errore exscrtum). 

 Hymenophyllum fuciforme, Colla in Mem. Accad. Sc. Torino, xxxix. p. 33, t. 63, non Swartz. 



Juan Fernandez. — On rocks in dark shady places in the mountains — Bertero ; 

 Cuming; Moseley. Masafuera. — Reed. 



Also a native of the neighbourhood of Valdivia and Chiloe. 



Following the indication on Bertero's label, Colla published this as Hymenophyllvm 

 fuciforme of Swartz, while to Swartz's plant he gave the name of Hymenophyllum semiteres. 

 In each case there is no difficulty in determining the species, independently of the exact 

 copies of Bertero's labels which Colla gives. 



Trichomanes pyxidiferum, Lion. 



Trichomanes pyxidiferum, Linn., Sp. PL, ed. 2, p. 1561 ; Hook., Sp. Fil., i. p. 124 ; Hook, and Grev., 

 Ic. FiL, t. 206 ; Hook, and Bak., Synopsis FiL, p. 81. 



Juan Fernandez. Moseley. 



Common in America, from Mexico southward to Chili ; in Tropical and South Africa, 

 and in India ; also occurring in North-Eastern Australia.
