12, Mertensia=Mecosorus, Hassk. The former name is preoccupied by a 



genus of Boraginacece. 

 species 7, glauca (Sw.), the oldest specific name. 



13, species 17. G.pallescens and rubiginosa, Mett. in Fil. Nov. Gran. p. 266, 

 are varieties of pubescens, as the species is here understood. 



19. Cyathea equestris appears to be a synonym of divergens. 



C. hirtula, Mart., appears to be a form of vestita. The species is 

 distinguished by its ultimate segments not more than a line broad, 

 very hairy frond and rachises, and very fragile involucre. 



C. Beyrichiana appears to be Alsophila setosa, Kaulf., and a Hemi- 

 telia, and therefore should be called H. setosa, Mett. MSS. 



25, species 46, for Mr. Lindsay read Mount Lindsay (in Queensland). 

 27, species 27. The Australian plant is probably C. medullaris.

30, species 14. H. Moricandiana, Kze. MSS., was previously published 

 by Presl (Die Gefass, p. 44) under the name of H. macrocarpa. 



32, species 3. Two quite distinct plants are here confounded. That to 

 which the name and diagnosis quoted from Martius refer is tripinnate, 

 and probably identical with species 11. The other appears to be 

 undescribed, and may be characterized as follows : 



A. pubescens, Baker ; caud. 6-10 ft. high ; st. 15-18 in. 1., densely 

 pubescent, not muricated, clothed below with rigid ovate-acuminate 

 scales \fr. oblong-deltoid, bipinnate, 3 ft. 1., more than 1 ft. br. ; lower 

 pinnae 6-8 in. 1., 1 j in. br., cut down nearly to the rachis into close 

 blunt lobes | in. br. ; texture herbaceous ; rachis and both sides densely 

 pubescent ; veinlets about 10 on a side, forked near the base ; sori at 

 the fork. 



Hab. Peru, Lechkr 2190, Spruce 4712 ; New Granada, Purdie. 



33. Species 8*. A. prcecincta, Kunze ; st. \\ ft. high, unarmed, glabrous, 

 dark-castaneous ; fr. subdeltoid, 4-5 ft"! 1., 3 ft. br., tripinnatifid ; 

 pinnce oblong-lanceolate, 1| ft, 1., 6-7 in. br., subequal below ; pinnl. 

 linear, 3-3^ in. 1., 9-10 lin. br., broadest at the base, cut down below 

 to a narrow wing, the point acuminate ; segm. linear-oblong, 2-2^ 

 lin. br., subobtuse, nearly straight, the barren ones crenulate ; texture 

 papyraceo-herbaceous ; both sides quite naked ; veins 7-8 on each side
