ASPIDIUM, § POLYSTICHUM. 21 



leatum. Simoda, Japan (true aculeatum), C. Wright, U. S. N. Pacif. Expl. Exped. 

 Polystichum polyblephariim, Kze. in Bol. Zeit. vi. p. 572 ; Mr. Wright justly ob-

8. Tkopical America. Much of the Aspid. aculeatum of tropical America is 

 the Aspid. Moritzianuni, A7. in Linn(Ba,x\. p. 367, and Aspid. ordinatum, Kze. in 

 Linncea. xviii.jw. 347, between which I can perceive no difference; and they quite 

 tally, some with the typical forms of aculeatum and var. angulare, others, from the 

 larger size, correspond with the usual tropical condition of tlie species. Abundant

 Aspid. paucicuspis, Sturm, may, I believe, be safely referred here. 



10. West Indian Islands. It is remarkable that I have seen no -well- 

 pronounced form of our present species from these islands ; unless a plant I have 

 received from Dr. Critger of Trinidad, " Serro de Arila," be from that island, as 

 it probably is, though the same package contained plants avowedly from the op- 

 posite mainland of Venezuela. The specimens quite resemble a rather small form 

 of the South American aculeatum, with pinnules a little more entire than usual. 

 This I possess also from C. IVright, Plantae Cubenses, ». 1056 (omitted m Eaton, 

 Fil. Wright et Fendi); it is proliferous at the apex, and the Polystichum hete- 

 rolepis. Fee, Gen. Fit. p. 279, allied to Polystichum viinparum, Fi'e, n. 17 of 

 this work, also from Cuba ; but it is throughout (excspt at the apex) bipinnate, and 

 in all other respects quite accords with acideatum. This seems to confirm an 

 opinion we have expressed under Aspid. viviparum, that this latter may be an im- 

 perfectly developed state of Aspid. aculeatum. 



11. S.\ndwich Islands. I possess no plant of the aculeatum-g;ro\ip from 

 these islands ; but Brackeitridge's Polystichum Ilaleakalense, Fil. U. S. E.rpl. 

 Exped. p. 204. t. 28, is from Hawaii. This I have little hesitation in referring to 

 aculeatum, and no peculiar form of it. Indeed, the author says, " .\llied to Aspid. 

 vestitum of Sw. (our aculeatum), from which, however, it is sufficiently distinct, 

 in the much smaller size of the whole plant, the shorter pinnae, and the deeper in- 

 cised pinnules."
