TETRAPOGON SPATHACEUS Benth. should be deleted. 



Engler & Prantl, Pfl. Fam. on Gramineae, p. 60, state that Tetrafogon 

 Desf. (Cryptochloris Benth.) has 5 species, 4 in North Africa, Abyssinia, 

 and West Asia; and i (Chryptochloris] elsewhere (Patagonia?). In my 

 copy of Speg. Plant. Pat. Austr. Spegazzini has left the following mar- 

 ginal note by Cryptochloris spathacea : "Elymus Kurtzii Speg.!" In this 

 he informs us that the determination, Cryptochloris spathacea, is wrong; 

 and the plant is identical with E. Kurtzii. 



Cf. F. Kurtz, Collectanea ad Flor. Argent., p. 259, "Cryptochloris 

 spathacea Speg. dans Rev. Fac. Agron. y Vet . . . est Elymus Spegaz- 

 zinii mihi, espece tres voisine (si non identique?) de 1' E. erianthus Phil.' 

 In 1908 Hackel informed me that Elymus Spegazzinii really is synony- 

 mous with E. erianthus Phil, this name being older than E. Spegazzinii. 



Hence we must delete Tetrapogon spathaceus Benth., without substitut- 

 ing anything, as the question is still unsettled. D.

PHRAGMITIS DIOICA Hack.
