450 ADDENDA ET CORRIGENDA. 



in a segment, simple or forked at the point, all soriferous ; sori sub- 

 marginal ; recept. naked. 



Hab. Bahia, JBlancJiet. General habit of Hemitelia, guianensis. Well 

 marked in the genus by its broad segments, subsimple veins, and nearly 

 marginal sori. 



Page 33, species 10. Apparently the same as species 21, which is the original 

 Cyathea aculeata, Willd. Herb. Spreng. ; but annata is an older name. 



34, species 16. Omit the synonyms quoted from Klotzsch and Martius. 

 Probably this is identical with species 24, and it only differs from 23 

 by the frond being subglabrous. 



35, line 37, for arillare read axillare. 



species 23, for Klf. read Kze., the plant of Kaulfuss, according to 

 Mettenius, being our species 16. 



40, species 43. A. Macarthurii, Hk. In consequence of Sir W. Hooker's 

 death, this sheet was in print nearly a year before it was issued, and 

 this plant was published by Dr. F. Mueller (Fragm. 5. p. 53) under 

 the name of A. Leichhardtiana, and by J. Smith (Brit, and For. Ferns, 

 p. 245) as A. Moorei. The former of the two has priority. 



Species 45*. A. Robertsiana, F. Muell. ; caud. 6 ft. high ; fr. ample, 

 oblong-deltoid, quadripinnatifid ; lower pinnae oblong-lanceolate, 12-18 

 in. 1., 4-6 in. br. ; pinnl. linear, 2-3 in. 1., f in. br., cut down to a nar- 

 rowly-winged rachis into deeply-pinnatifid linear-oblong segm. \ in. br. ; 

 texture herbaceous ; rachis and both surfaces densely villose ; sori 1 to 

 each lower ult. lobe. Fragm. 5. p. 54. 



Hab. Queensland, Messrs. Dallachy & Hill. Nearest A. Colensoi, the 

 segments the same size, but here deeply pinnatifid, the rachises of the pinnae 

 and pinnules without scales, and the whole plant more hairy. 



A. Rebecca?, F. Muell. ; caud. slender, 8 ft. high ; fr. ample, bipin- 

 nate ; lower pinnae oblong-lanceolate, 12-15 in. 1., 4-5 in. br. ; pinnl. 

 20-30 on each side, the lower ones stalked, linear, 2-3 in. 1., f in. br., 

 the apex acuminate, the upper part deeply, the lower less deeply inciso- 

 crenate, the base rounded on both sides, slightly auricled above ; texture 

 subcoriaceous ; rachises reddish-brown, slightly fibrillose, the main one 

 rough, with raised points ; upper surface naked, lower scattered over 

 with small membranous scales ; veins fine, 4-5 in a group ; sori prin- 

 cipally in 2 rows midway the midrib and edge. Fraqm. 5. p. 53. 

 Hk. Ic. t. 1015. 



Hab. Rockingham Bay, Messrs. Hill & Dallachy. Very near A . podophylla, 

 but the veins few, and under surface with small scattered scales. 



47. Species 4*. Woodsia scopulina, Eaton ; st. tufted, not articulated, cas- 

 taneous at the base, stramineous upwards, 2-3 in. 1., the scales brown, 

 ovate-acuminate ; fr. lanceolate, bipinnate, 3-4 in. ]., 1-1 in. br. ; 

 pinnae oblong-lanceolate, cut down to the rachis below into 6-10 

 narrow-oblong crenate pinnl. on each side ; texture herbaceous, the 

 whole plant pubescent and glandular ; inv. with both cup and cilia 

 almost hidden by the sorus. Canad. Nat. April, 1865. 

 Hab. Rocky Mountains and British America. 



W. oregana., Eaton, is our obtusa (3 Lyallii, but evidently a distinct 

 species, with the involucre of Euwoodsia, general habit of obtusa, but 

 smaller, and not so hairy. Can. Nat. I. c. 



Hab. Oregon and Rocky Mountains. This and the preceding differ from 

 species 1-4 by their inarticulated stems. 



Species 7 is DicJcsonia fragilis,Trev. (1816), Woodsia, Moore. See 

 Milde, Fil. Eur. p. 167.
