 Cordova, Dr. Gillies. Monte Video, Capt. Philip King, R.A\ Uruguay, Mr. 

 Fox. Buenos Ayres, Gillies, Iweedie. — (See our observations under the last 

 species, BL australe.) Tlie now greatly extended localities of these two species, 

 and allowing for a little modification in the position of the sorus between the 

 costa and the margin, may tend to confirm the view I have long entertained 

 that the two are not permanently distinct. My own Blechnum pubescens I 

 am very willing to sacrifice, and to consider a young state of the present, but 

 the sori are certainly more marginal than the ordinary form of Bl. hastatum. 

 Schlechtendal did not hesitate to unite the South American Bl. auriculafum of 

 Cavanilles (from B. Ayres) — probably the same as our hastatum — with the 

 African Bl. australe. The lobes at the base of our present species are extremely 

 variable, as shown by Kunzc, and that able botanist has, with equal accuracy, 

 represented the continuous and the interrupted forms of the sori, so interrupted 

 sometimes and with so much regularity as quite to resemble the fructifications of 

 a Doodia, a peculiarity however which is common also to Bl. australe.

Hab. Cape of Good Hope, Burmann 1, Drege (Presl). — This is scarcely known 

 but by the brief diagnosis of Swartz, who says of it, " Differt a Blcchno australi, 

 L., quod frondes majores, rigidiores ; pinna; angustiores, obtusa; (nee submucro- 

 nata^), et terminales confluentes." Pappe and Rawson do not acknowledge the 

 species in their Synops. Fil. Afr. Australis. — If Presl is right in referring Drege's 

 Lomaria punctulata to the Blechnum rigidum of Swartz, these two must be 

 united, for Droge's plant is correctly so named, at least in my specimens from 

 Drege. 



26. Bl. ciliatum, Pr. ; " fronds elongato-lanceolate pinnate, 

 pinncc sessile horizontal ciliate auriculate on each side at the 

 base, sterile ones oljlongo-lanceolate mncronate, fertile ones 

 linear acute, lowest ones opposite ovato-lanceolate, stipes 

 and rachis pubescent and paleaceous." Pr. Reliq. Hank,
