flattened or slightly so either before or after the first fork. — Sturm in Mart. Fl.

Hab, Guiana and Brazil. — Perhaps this should be considered a reduced variety of 

 ele^ans. 



12. S. (Loph.) Sprucei, Hk. ]\ISS. ; caud. woody, suberect ; 5^.9-12 in 1., firm, 

 dense, erect, clothed, especially below, with squarrose fibrillose brownish scales; 

 //•. G-8 in. 1., very thick in texture, naked, channelled, | in. br. at the widest 

 part, narrowed gradually downwards, bearing at the apex 1-6 long-stalked 

 fertile segm., which aTre 1^-2 in. 1., the rachis spirally recurved, the spikes very 

 numerous, f-f in. 1., tomentose beneath. — Hk. Ic. t. 1016. 



Hab. Banks of the Rio Negro, S^rruce 3752. — A very distinct new species. 



13. S. (Loph.) dichotoma, Sw. ; st. 6-18 in. 1., firm, erect, glossy, channelled 

 on the face above ; /;'. faulike in general outline, 6-9 in. each way, many times 

 dichotomously forked, the ultimate divisions \-\ lin. br., with 1 fertile segm. to 

 each, \-\ in. 1., the rachis often curved, with 4-10 close, spreading spikes on each 

 side. — Hk. & Gr. t. 17. Bcddome, t. 65. S. Forsteri, *S>r. S. cristata, Willd.

Hab. Cuba, Venezuela, Peru, Polynesia, Australia, New Zealand, Philippines, Ma- 

 laccas, Neilgherries, Mascaren Isles. — The Polynesian S. cristata, Willd., is a large form 

 with broader divisions than usual. The American plant is S. occklentalis, Griseb., and 

 is said to have the fertile segment twice as long as in the type ; but we do not find the 

 character to always hold good. 



14. S. (Loph.) elcgans, Sw. ; st. 6-12 in. 1., firm, erect, naked ; fr. like the 

 letter V in outline, 4-8 in. each way, dichotomously forked or cleft, the divisions 

 varying greatly in number and breadth (j-2 in.), surface glossy; fertile segm. 

 copious, distinctly stalked, |-f in. 1., the rachis often recurved with 6-15 close 

 spreading linear-cylindrical spikes on each side. — Hk. G. F. t. 54. — /3, S.flahellum^

 spectabilis, Mart. Sturm. Fl. Bras.fasc. 23. t. 14. 



Hab. West Indies and Mexico to Brazil. — S. attenuafa, Beyr., appears to be a form 

 with unusually narrow divisions. S. pacificans, Mart. Icon. Crypt, t. 56, has two entire 

 divisions, each 6 in. br.

15. S. (Actin.) pennula, Sw. ; st. dense, 1-2 in. 1., subterete, brownish, passing 

 gradually into the //•., which is 1 ft. or more 1., nearly 1 lin. thick, triquetrous, 

 with 3 sharp angles, crowned at the apex with 6-12 subtriquetrous fertile, 

 spikes, which are \-\\ in. 1., pilose beneath, with the caps, usually in 4 rows.—

 often reduced to 3 or 4. — Kunze, t. 97./. 1. A. Germani, Fee, Fil. Ant. t. 29. 



Hab. West Indies to Rio, New Caledonia, Isle of Pines, Seychelles. — We csnnot 

 distinguish the Polynesian S. IcBvirjata from the American plant. The New Caledonian 

 S. intermedia, Mett., is intermediate between our two varieties. 



16. S. (Actin.) digitata, Sw. ; st. dense, 1-2 in. 1., brownish, subterete, passing 

 gradually into the fr., which is 1 ft. or more 1., 1-2 lin. br., flattened, the 

 midrib beneatli prominent, crowned at the apex with 6-15 subtriquetrous 

 fertile spikes, which are 1| in. 1., naked beneath, with the caps, in 4 rows and 

 the edge much inflexed. — Hk. G. F. t. 54.
