when fully developed ; panicle close, 1-2 in. 1., lanceolate-deltoid, bipinnate. 

 fix. Br. F. t. 48. 



Hab. Arctic Europe and Iceland to Spain, Italy, Kamschatka, and the Himalayas 

 South Australia, Tasmania, Patagonia, N. W. America, Greenland, Newfoundland, 

 Canada. 



4. B. ternatum, Sw. ; st. 1-2 in. 1. ; petiole of the sterile segm. 2-4 in. 1., the 

 latter 3-6 in. each way, deltoid, tri- or quadripinnatifid ; lower pinnae much the 

 largest, and pinnl. of the lower side larger than the others, oblong or subdeltoid, 

 stalked, the ult. divisions oblong or obovate, often J in. br., blunt or acute, 

 slightly toothed ; fertile peduncle 6-9 in. 1., considerably overtopping the sterile 

 segm. ; panicle 1-6 in. 1., deltoid, very compound. Kunze, t. 121. Osmunda, 

 Thbg. Fl. Jap. f. 32. 



Hab. Nootka and Hudson's Bay territory southward to New Granada, Australia, 

 Tasmania, New Zealand, Lapland, to Siberia, Japan, Pyrenees, and Hungary. Of this 

 the European B. matricarioideSf^Willd. (B. rutcefolium, A. Br. & Koch), and the American 

 . lunarioides, Sw. (A. Gray, Man. t. 13), appear to be smaller, and the Australian 

 B. auslrale, R. Br., and the American B. obliquum, Muhl, and B. decompositum, M. & G., 

 larger and more divided forms. B. silaifolium, Presl, seems also to belong here. B. dis- 

 sectum, Muhl, is a curious form or variety, thinner in texture than the type, with the 

 ultimate divisions acute and sharply inciso-serrate, which occurs both in the United 

 States and New Zealand. 



** Texture thinner. Sp. 5-G. 



5. B. daucifolium, Wall. ; st. stout, 6-12 in. 1. ; petiole of sterile segm. 1-6 in. 1., 

 the latter 6-12 in. each way, deltoid, tripinnatifid or tripinnate, the lower pi nnce 

 much the largest ; segm. lanceolate -oblong, - in. br., finely toothed ; fertile 

 peduncle about equalling the sterile segm. when mature ; panicle 2-4 in. 1., 

 tripinnate, not very close. Hk. & Gr. t. 161. B. subcarnosum, Wall. Moore, 

 Beddome, t. 78. B. subbifoliatum, Brack, t. 44. 



Hab. Himalayas, Neilgherries, Ceylon, Japan, Java, Sandwich and Society Isles. 

 Distinguished from the next by its much less finely-cut fronds and stalked sterile seg- 

 ment. The Polynesian and Japanese specimens are forked considerably lower down 

 than the Indian ones, and Brackenridge's plate represents a pair of barren segments to 

 the stem. 



6. B. virginianum, Sw. ; st. 3-18 in. 1. ; sterile segm. sessile, 4-12 in. each way, 

 deltoid, quadripinnatifid ; lower pinnae much the largest ; pinnl. ovate-oblong, 

 close, cut down to a broadly-winged rachis into finely cut linear-oblong segm. ; 

 both sides naked ; fertile peduncle equalling or overtopping the sterile segm. 

 when mature, arising from its base ; panicle 1-4 in. 1., lax, oblong, generally not 

 more than bipinnate. Hk. G. F. t. 29. B. cicutarium, Sw. B. anthemoides, 

 Presl. B. brachystachys, Kze. B. lanuginosum, Hk. fy Gr. t. 79. ft, B. 

 lanuginosum, Wall. ; surface slightly hairy, fertile peduncle arising from the 

 centre of the sterile segm., which the panicle scarcely overtops. Beddome, t. 77- 



Hab. Oregon and North United States to Ecuador and Brazil ; Norway to Austria, 

 the Himalayas, and Tsus-Sima ; /3, Himalayas (up to 6,000 ft.), Neilgherries, Ceylon. 

 The leaf in cutting resembles that of Anthriscus sylvestris.
