at base, marginal cells 20 to 25. Prof. Evans writes "I have 

 examined with much interest the Herherta from Dominica, collected 

 by Miss Armitage, but have not reached a definite decision about it. 

 It bears a good deal of resemblance to H. commutata (Steph.), which 

 Stephani reports from Guadeloupe as well as from Ecuador, the type 

 locality.^ Have you compared it with that species? I wish that 

 Stephani had published figures of his new species. If the Dominica 

 plant proves distinct from H. commutata, I think it would be safe to 

 describe it as new." R. commutata (H. jyeiisilis Spruce non Taylor), 

 Hep. Am. et And.), of which there are fine specimens in the Man- 

 chester Museum, is a much more delicate , species, with distant, 

 squarrose leaves, not secund, vitta 18 cells wide, marginal cells 10 on 

 each side. 



H. costaricensis (Steph.) and H. angustifoUa (Steph.) which 

 have entire leaves, are described as with distant squarrose leaves. 

 I have not seen specimens of these. 



There are specimens in the Manchester Museum (n. 20247) named 

 '* Sendtnera juniperina, M. Perrim, Guadeloupe, Dr. Madiano," 

 which Austin has named Sendtnera pensilis Tayl. 



This, according to Taylor's original description (in Lond. Journ. 

 Bot. V. 372 ; 1846) is a plant a foot long ; he says *' the simpler, 

 subcompressed elongated, waved and pendent stems, and more distant 

 leaves easily separate this from S. jvniperina:' Stephani describes 

 H. pensilis, with coarsely laciniate leaves ; I have not been able to 

 examine Taylor's original specimen. 



The specimen, from Guadeloupe agrees exactly with those collected 

 by Miss Armitage in Dominica.

Dioicous, largish to large, dark to pale brown. Stems slightly 

 branched, strong, wiry. Leaves approximate, subimbricate, alternate, 

 patent-divergent to patent, 70°-50°, triangular, apex obtusate, sub- 

 truncate ; antical margin curved, decurrent, recurved, with 1 to 3 

 teeth ; apex with 3 to 5 long spines ; postical margin with about 

 15 long spines, 4 to 7 cells long, ampliate, crossing the stem slightly, 

 near the postical base sub-rotund, wdth 1 or 2 long spines. 



Named by Stephani P. dominicensis, and recorded as such in Sp. 

 Hep. p. 576, Dominica (Armitage). In his notes he says '* I have 

 not had the opportunity of examining the original, so describe the 

 plant from the above, Dominica (Armitage, Eggers), Guadeloupe 

 (I'Herminier), which agree perfectly with the original description. 

 The comparison of the authors (Taylor & Gottsche?) with P.siiperba 

 is strikingly exact. Gottsche had' this plant (legit FHerminier) as
