88 NORTH AMERICAN FLORA [VoLuME 16 
yellowish or grayish-brown, quickly breaking into numerous fragments, few of these 
persistent ; receptacle relatively large, elevated, capitate, dark-brown, setiferous, fragile. 
TYPE LOCALITY: Jalapa, Mexico. 
DISTRIBUTION : Humid regions of Vera Cruz, Mexico, southward to Chiapas and Alta Verapaz, 
Guatemala, up to 1300 meters altitude; also in Costa Rica. 
DOUBTFUL OR EXTRALIMITAL SPECIES 
Cyathea conqutsita Jenman, Jour. Bot. 20: 324. 1882. Known only from the orginal 
specimens from Jamaica, Wilson 134, in the herbarium of the British Museum (Natural 
History). See under C. pendula Jenman, below. 
Cyathea fulva (Mart. & Gal.) Fée, Mém. Foug. 9: 34 (25). 1857. (Alsophila fulva 
Mart. & Gal. Mém. Acad. Brux. 155: 78. A/. 23. 1842.) Type from the forests of Villa 
Alta, Oaxaca, Mexico, altitude 1500-1800 meters, Galeotti 6346. Apparently a very fertile 
contracted form of C. mexicana, but only fragments of the original number have been seen. 
Cyathea guadeloupensis Spreng. Nova Acta Acad. Leop.-Carol. 10: 233, 1821. Very 
briefly described upon Guadeloupe specimens collected by Bertier and Perrin. Referred by 
Christensen to C. arborea, but whether rightly or not is problematical without an exami- 
nation of the original specimens. 
Cyathea moniliformis Jenman, Ferns Brit. W. Ind. 59. 1898. ‘According to the 
original description the source of the type specimens is unknown. Christensen (Index 
Fil. 193. 1905) attributes the species to Central America. The specimen of the Jenman 
herbarium at the New York Botanical Garden is marked as from Trinidad, probably with 
correctness, and the species thus falls without the range of the present treatment. 
Cyathea monstrabila Jenman, Jour. Bot. 19: 275. 1881. Founded upon specimens 
collected by Nock in the high forest near Portland Gap, in the Blue Mountains of Jamaica, 
altitude 1500-1800 meters. Jenman subsequently (Bull. Dep. Agr. Jamaica 29: 7. 1892) 
regarded it as evidently an abnormal state, possibly of a species otherwise unknown, and 
called attention to differences in vestiture and color distinguishing it from C. furfuracea 
Baker and the species here described as C. Harrisii. The type specimens (herb. N. Y. 
Bot. Gard.) appear to the writer to represent a juvenile monstrous form of a species nearest 
C. furfuracea, or possibly of that species itself. 
Cyathea muricata Willd. Sp. Pl. 5: 497. 1810. Founded upon Plumier’s plate ¢ 
(Traité Foug.), representing a plant from Martinique. Baker, following Kaulfuss, has 
regarded Sieber’s xo. 374 from Martinique as agreeing with the plate; but the resemblance 
is slight. Sieber’s plant is a large state of Cyathea tenera ; and the plant figured by Plumier 
is, so far as the writer knows, yet to be rediscovered. The C. muricata of Grisebach is said 
by Christensen to be C. furfuracea Baker. Costa Rican specimens (P%éttier 1839) deter- 
mined by Bommer as “‘ Cyathea muricata Willd. (non Kaulf.)’’ are Cyathea onusta Christ. 
Cyathea papyracea Christ, Bull. Herb. Boiss. II. 4: 946. 1904. Very briefly described 
from Costa Rican specimens, Werckié52. From fragmentary material seen it appears to 
be closely related to C. onusta or to be possibly a form of that species. 
Cyathea patens Karst. Fl. Columb. 2: 173. pl. 197. 1869. A Colombian species 
recorded from Costa Rica by Bommer and Christ (Bull. Soc. Bot. Belg. 32: 176. 1893) 
upon the basis of specimens collected on the volcano Irazfi, altitude 2000 meters, Pittier 
4175, These, however, are Cyathea suprastrigosa (Christ) Maxon, only superficially 
resembling C. patens. 
Cyathea pendula Jenman, Jour. Bot. 20: 324. 1882. Known only from the original 
specimens, Jamaica, Wilson i6, in the herbarium of the British Museum (Natural History). 
This and Cyathea conguisita (mentioned above) were founded upon material regarded by 
Jenman as ‘‘ insufficient to show whether they are simply bipinnate or tripinnate species’’; 
the former supposition was ‘‘inferred from the fact of the rachises being channelled.’’
