210 ACROSTICHUM, § ELAPHOGLOSSUM. 



Insulae Sanctje Helenae ;" since collected by Sir G. Staunton, Menzies, Shuier, 

 Cuming, n. 420 and 421, Nuttall, Lady Dalhousie, Dr. Lyall, Seemann, J. D. 

 Hooker, Haughion, etc. — A very curious and certainly very peculiar form for an 

 Acrostichum ; yet from its close natural affinity with A. dimorphicm, I should be 

 unvFilling to separate it from that genus (as Presl has done), nor can I see any 

 good to be derived from so doing. We have abnormal species in plenty and must 

 expect abnormal genera. 



** Fronds more or less soft or suhflaccid. 33, 44. 



33. A. (Elaphoglossum) Boryanum, Fee ; caudex large 

 creeping knotty the upper part densely ferrugineo-paleaccous 

 with large ovato-lanceolate scales, stipites aggregated 3-5 

 inches to a foot long (and in one of our sterile specimens 

 nearly 2\ feet long) copiously furfuraceo-squarrose with 

 spreading brownish sublanceolate scales but varying in size 

 and shape and more or less deciduous ; sterile fronds firm- 

 membranaceous subpellucid 8-10 inches to 12-15 inches 

 long 2\ (in one instance) to 5 inches broad oblong acuminate 

 or often notched and proliferous at the apex broadly cuneate 

 at the base minutely ciliato- serrate and often fringed with 

 scales when young, dotted more or less on both sides with 

 minute fringed scales, costa piloso-squamulose ; fertile fronds 

 smaller and narrower 6-8 inches long 1 inch wide. — Fee, 

 Acrost.p. 40. Elaphoglossum, Moore. 



Hab. Tropical America: Guadeloupe, VHerminier, in Herb, nostr.; Mar- 

 tinique {Fee); Dominica, Couliabon Mountains, Dr. Imray ; Trinidad, Crnger ; 

 Ecuador, on trees foot of Chimborazo, alt. 3000 feet, Spruce. — One specimen 

 including stipes, from Mr. Spruce, measures 3^ feet long, and some very young 

 fronds which we possess are caudato-acurainate at the apex and fringed with 

 scales at the minutely serrated margin. 



34. A. (Elaphoglossum) hyhridum, Bory; caudex stout 

 creeping knotty, where the stipites arise densely clothed with 

 silky slender glossy narrow-subulate dark purple-brown or 

 almost black scales, stipites aggregated 4-6-7 inches long 

 generally slender flexuose stramineous or tawny paleaceo- 

 villous with rather sparse long subulate horizontally patent 

 brown scales 2-3 lines long; sterile fronds submembrana- 

 ceous rarely subcoriaceous usually subpellucid 5-10 inches 

 long 1^-2 inches broad oblong-lanceolate acuminate obtuse 

 rarely attenuated at the base, the margin and partially the 

 costa beneath especially near the base fringed with long soft 

 subulate brown hairs, costa nearly plane on both sides, veins 

 manifest subhorizontally patent ; fertile frond smaller 3-5 

 inches long rarely 1 inch wide oblong obtuse with a stipes
