GLEICHENIACEAE. 



Genus 2. GLEICHENIA Sm. 



3. G. circinata, S\v. I cannot separate specifically G. patens, 



Colenso in Trans. New Zeal. Instit. 1888, 212. 



4. G. rupestris, R. Br., must evidently be placed as a mere variety 



of G. circinata. 

 8. G. littoralis, Colenso, in Trans. N. Zeal. Inst. 1883, 334, I 



cannot separate from G. flabellata. 

 12*. Mertensia littoralis, Philippi, Descr. Nuev. Plant. 1873, 104. 



Chili. Not seen. 

 15. G. subandina, Sodiro, Recens. 5, and G. hypoleuca, Sodiro, 



Recens. 8, Andes of Ecuador, I should place as varieties of 



G. revoluta. 

 17. G. seminuda, Moore, Ind. Fil. 383, Columbia, G. blepharilepis, 



Sodiro, Recens. 6, and G. leucocarpa, Sodiro, Recens. 8, Andes 



of Ecuador, I should place as varieties of G. pubescens. 

 17*. G. intermedia, Baker, in Journ. Bot. 1887, 24. Costa Rica, 



Cooper, Intermediate between pubescens and dichotoma. There 



are two varieties, flexuosa and dissitifolia. 

 19. G. Brackenridgei, Fourn. in Ann. Sc. Nat. sdr. 5, XVIII, 269, 



New Caledonia and Fiji, and G. oceanica, Kuhn, Hook, and 



Baker, Syn. Fil. edit. 2, 449, should probably be classed as 



varieties of G.flagellaris. 



23. G. linearis, Clarke, in Trans. Linn. Soc. ser. 2, I 428, (Poly- 

 podium lineare, Burm.), is a synonym of G. dichotoma, Hook. 



CYATHEACEAE. 



Genus 4. CYATHEA Sm. 



Bommer proposes to divide Cyathea into three genera, viz. i, 

 Cyathea, indusium of one single indehiscent piece; 2, Eatoniopteris, 

 indusium of one piece, membranous, breaking up into fragments; 

 3, Fourm'era, indusium formed of a number of narrow hyaline im- 

 bricated scales. For my own part, I feel more inclined to unite 

 Hemitelia to Cyathea than to divide Cyathea as it now stands. 



NEW WORLD SPECIES. 



3*. C. Nockii, Jenm., in Journ. Bot. 1879, 257. Jamaica, Nock. 

 Indusium of C. arborea, but frond bipinnate.
