Sagenia longicrure Christ in Bull. Geogr. Bot. Mans. (1906) 250. 



Stipe to 30 cm. or more long, shining, reddish-brown, glabrous; frond deltoid- 

 oblong, 40 cm. long, 35 cm. broad, bipinnate to tripinnatifid in the lower part, rachis 

 and the base of costa shining, light ebeneous, deeply grooved above; terminal pinna 

 large, petiolate, deeply trilobate, deltoid, the central lobe oblong, 15-30 cm. long, 5-10 

 cm. broad, margin coarsely repando-lobulate, with the base of lobes broadly adnate, 

 cuneat-elongate, repand; lateral pinnae 3 on each side, opposite, 12-16 cm. apart, the 

 lower ones 14 cm. long, the uper ones 8 cm. long, long-petiolate, the uppermost ones 

 subsessile, oblong, caudate, with obtuse hastate base, the middle pinnae deeply 3-lobed 

 down to the base, the lowest pinnate; pinnules 2, farapart, petiolulate, with hastate or 

 deeply lobed base, the terminal pinnules deeply trilobate; all pinnae ascendingly patent, 

 the uppermost pinnules to 10-13 cm. long, 4 cm. broad, margin repando-crenate, all 

 pinnae and pinnules acuminate, or long caudate; lateral veins prominent, almost reaching 

 the margin, areolae irregularly quadrangular, in 2-3 rows between main veins and about 

 6 between costa and margin, usually without free included veinlets; sori very numerous, 

 campital or dorsal, small, almost punctate, dark brown, irregularly disposed, inducium 

 destitute; texture thin herbaceous, lustrous green, surfaces naked but the costa and 

 veins are shortly pubescent. 



Distribution: Kweichow, Kwangsi. 



A bipinnate species of the group of A. cicutarium Sw., very distinct in pinnae and 

 lower pinnules being long-petiolate, narrowly elongate, few-lobed pinnules and segments 

 with very long-acuminate apex, stipes and rachis reddish-ebeneous, polished, and very 

 small irregular exinduciate sori. Collected for the first time by Pere Cavalerie in Kwei- 

 chow, (1904), later by J. Esquirol in the same locality and of very late from Kwangsi.
