FROM THE SOLOMON ISLANDS. 295 
Pinnæ with a large rounded auricle on each side at the base, 
imbricated over the rhachis, and sori forming only a single row 
nearer the margin than the midrib. 
Gathered previously in San Cristoval by Milne. 
NEPHRODIUM (Š LASTREA) Harveyi, Baker. 
NEPHRODTUM (Š EUNEPHRODIUM) TRUNCATUM, Presl. 
NEPHRODIUM (Š EUNEPHRODIUM) AMBOINENSE, var, SUBGLAN- 
DULOSUM, n. var. 
A form intermediate between N. amboinense and glandulosum. 
The sterile pinne rather broader than in typical amboinense and 
shallowly lobed ; the fertile pinne entire, not more than 3 in. broad 
at the base, narrowed gradually to the very acuminate apex; the 
main veins š in. apart, the veinlets simple, erecto-patent, 4—5- 
Jugate, with a small median sorus on each of them. 
213*, NEPHRODIUM (Š SAGENIA) HEDERJEFOLIUM, n. sp. 
Stipite nudo castaneo, frondibus cordato-deltoideis profunde pinmati- 
fidis parvis papyraceis glabris, segmentis primariis subtrijugis, superiori- 
bus parvis integris, infimis multo majoribus inzequilateralibus latere inferiori 
profunde lobatis, venis przeter primarias rectas in areolas copiosas parvas 
anastomosantibus, soris magnis subregulariter seriatis. 
Stipe 6-9 in. long, naked, slender, castaneous. Frond cordate- 
deltoid, simple, 4 ft. long and broad, palmately lobed at the base 
Within a short distance of the rhachis, membranous, green and 
glabrous on both surfaces; the lower lobes much the largest, 
deeply pinnatifid on the lower side, with oblong segments; the 
central segments of the main frond erecto-patent, oblong-lanceo- 
late, subacute, reaching about halfway down; the other lobes 
very short. Areole very small and very distinct, with copious 
free included veinlets. Sori few, large, arranged in rows near 
the main veins. Involucre large, reniform, glabrous, persistent. 
Most like Aspidiwm platanifolium in the size and outline of the 
frond, with sori and involucre as in Nephrodium ($ Sagenia) Pica.

apice profunde pinnatifidis, venis primariis rectis, reliquis in areolas parvas 
Copiosas anastomosantibus, soris magnis in seriebus regularibus prope venas 
primarias dispositis.
