32 IIEMITELIA. 



Hah. Britisli Guiana, C. S. Parker, Esq, — I do not find tliis anywhere 

 described, nor am I clear that it shoukl not he placed in Cyathca. In 

 halnt and form of the pinnules it has the closest affinity with the following; 

 but the involucre is dissimilar. 



9. H. ? Parkeri, Hook. ; unarmed ? fronds bi-tri-pinnate? 

 main rachis slightly scaly and together with the lesser rachis 

 costa veins (more or less) and margin clothed with numerous 

 spreading hairs, rachis between the ])innules distinctly wing- 

 ed, pinnules sessile oblong-lanceolate bluntly acuminated 

 pinnatifid about half way down subcoriaceo-membranaceous 

 segments ovate obtuse entire, veins all free forked above the 

 middle and bearing the sori (several in each segment) in the 

 axil of the fork and rather nearer the margin than the costa, 

 involucre rather small ciliated dimidiate often bifid in age.

Hab. British Guiana, C. S. Parker, Fsc/. — The win<^ed rachis, very dis- 

 tinct in the upper part between the pinnules, is a striking character in this 

 and the preceding species : but this is easily recognized by its copious hairs 

 and more abundant sori and very different involucre, which I think may be 

 considered entirely that of a Hemifelia ; though the general habit approach- 

 es nearer that of a true Cyathca or Alsophila.

 long-lanceolate acuminate pinnatifid, segments oblong obtuse 

 obtusely serrated, rachis winged, caudex arborescent." Willd.

Hab. Jamaica; ex Herb. Banks. (Smith). — With this I am unacqnaint- 

 ed, and Mr. Brown is the authority for its being referred to Hemitelia. Sir 

 Jas. Smith, with whom tlie species originated, has merely said of it (under 



Cyuthea) " Caudice , fronde bipinuata pinuatifida, laciniis obtusis ser- 



ratis, rachi alata, floribus sparsis, calyce lacero." Willdenow, who seems 

 to have been acquainted with the species, and whose character I have given 

 above, further remarks upon it, " Rachis margined on eacli side with a nar- 

 row decurrent line. Partial pinnae 2 feet long. Pinnules 4 inches long, an 

 inch broad at the base, lanceolate, acuminate, pinnatifid. Segments 5 lines 

 long, oblong, rather acute, obtusely serrated." Unfortunately neither Smith 

 nor Willdenow alludes to the venation, nor, except the brief notice of the 

 former, to the involucres. ]\Ir. J. Smith, who, as well as Mr. Gardner, has 

 examined the original specimens, says that, as far as can be judged from 

 the imperfect specimens, it differs from the preceding (H.? Parkeri) only 

 in wanting the coarse hairs on the racliis. jNIr. Gardner considers it allied 

 to Alsophila Capensis. 



Doubtful Species. 



11. H. tnunita. Cnemidaria munita, ZV. Cyathea, IVilld. 

 Hab. ? — This, to the best of my knowledge, is luiwhere described. 



Presl places it in Cneviidaria, whence 1 have noticed it here.
