412 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
in dry spots during the rains. The floating and the erect forms both produce their barren 
and fertile fronds. In ditches the rhizome is somewhat creeping and stout.

[Beddome (Brit. Ferns, Suppl. p. 9) states that Lomaria Patersoni, Spreng., Hk. & 
Baker, Syn. Fil. 174, is generally distributed in India; but I never heard of its being 
collected in North India, and in the Kew Herbarium there is no specimen north of the 
Nilgherries. | 
Sect. Plagiogyria. Base of stipe dilated, triquetrous. Capsules with an oblique ring. 
1. L. ADNATA, Blume, Enum. Pl. Jav. Fil. 205. More than half the pinnze of the barren 
frond sessile adnate.—Hook. Sp. Fil. iii. 19, t. 147; Hk. & Baker, Syn. Fil. 182. 
L. euphlebia, Hook. 2nd Cent. Ferns, t. 89, not of Kunze. Plagiogyria adnata,

Khasia ; alt. 4000-5000 feet, plentiful.—Distrib. Java, Japan. 
Pinnæ of the barren frond usually approximate, often all adnate, so that the frond is ` 
pinnatifid, scarcely pinnate; pinne often faleate, simply serrate, or nearly entire in their 
lower portion, varying from scarcely acute to caudate.—The Indian L. adnata is easily 
separated from L. euphlebia, but the Japan critical examples unite the two species, 80 
that I cannot name them. The typical L. adnata is sent from Japan; but Maximowicz 
names the whole series Z. euphlebia, Mett.—As to the name L. adnata, Blume, the only 
example from Java so named is a portion of a fertile frond quite impossible of deter- 
mination. The Khasi plant may yet turn out something quite different from L. adnata. 
2. L. etauca, Blume, Enum. Pl. Jav. Fil 204. Lower pinns of the barren frond 
white-glaucous beneath, minutely serrate in their lower half, suddenly truncate to 
a very short stalk.—Kunze, 2nd Suppl. to Schkuhr, t. 138; Hook. Sp. Fil. iii. 22; 
Hk. & Baker, Syn. Fil. 182, Plagiogyria glauca, Mett, Farn. Plagiog. 9; Bedd.

Khasia, alt. 4000-5000 feet; Moflong Wood, Hk. f. & T.; Vale of Rocks, Upper 
Kalapani, Sohra Reen (Surareem), O.B. Clarke.—Distrib. Java. 
I think only a var. of L. pycnophylla, powdered beneath. There is no difference 
between the two in the degree of serration and acumination of the points of the pinnt, — 
or in the frequency of the presence of a gland at their base. F. Henderson observé — 
that the lower pinnæ, not the mere auricles, are distant. Some of the Java Z. glauca | 
are much larger than the Khasia, s 
3. L. rxcoPHYLLA, Kunze, in Bot. Zeit. 1848, 143. Lower pinns of the barren frond -
