ANGIOPTERIDACEA 
ARCHANGIOPTERIS CAUDATA Ching, sp. nov. 
Rhizomate suberecto, ca. 2 cm crasso, radicoso; stipite 30-45 cm longo, 3-4 mm diametro, virescenti, 
subglabro, circ. 16 cm supra basin tumide nodoso et geniculato; lamina ambitu ovata, 30 cm longa, ca. 
25 cm lata, impari-pinnata; pinnis uti videtur 2-jugis, suboppositis, 5-6 cm inter se remotis, pinna terminali 
paulo majore, 16-18 cm longa, 45-5 cm medio lata, lateralibus omnibus similibus, vel infimis vix breviori- 
bus, late oblanceolatis, basin versus gradatim angustatis, basi cuneatis, apice subito caudatis (cauda 1.5 cm 
longa, lineari, serrata), margine e basi sursum grosse dentatis; textura herbaceo-chartacea, virescenti, 
utraque facie subglabra, secus costam et venulam squamis minutis lanceolatis sparsis conspersis; venis sub- 
recte patentibus, sub angulo ca. 60° excurrentibus, plerisque furcatis, nonnullis simplicibus, intra marginem 
antrorsim curvatis et in dentes intrantibus; sorzs 8-10 mm longis, ca. 6 mm a margine et costa remotis, 
subcontiguis; sporangiis 40-70 pro soro vel rarius pluribus, receptaculo paulo elevato, pilis quam sporangiis 
multo brevioribus, rufis, articulatis, e basi dense ramosis praeditis; sporis globulo-tetraedribus, minutissime 
denseque echinatis. 
Southern Kwangsi: Min River, Kang Nu Shan, specimens ex Herb. Kwangsi University, in ravine 
under forest, about halfway up the mountain, Oct, 2, 1935. 
A very distinct local species, differing from A. Henryi Christ et Gies. in oblanceolate pinnae with 
abruptly caudate apices, coarsely dentate leaf-margin and in the very short and profusely branched para- 
physes so completely hidden under the sori that their presence can hardly be detected from above, or 
without the sporangia being carefully removed off the veins.

3. Scale from the lower part of stipe (X 30). 4. Two sporangia attached to the receptacle with very short paraphyses 
(X 20). 5. Paraphyses removed from the sori (X 100). 6. Spores (X 100), one enlarged (X 400).
