The genus Zindsea of Dryander presents some discrepancies in its fructification, which have 
induced succeeding authors to divide it into different genera. Among these, is the ScAizoloma of 
Gaudichaud, distinguished by having the involucres double; that is to say, the margin of the frond 
apparently forms a portion of the involucre, and corresponds with the involucre itself; whereas in 
most of the true Zindsee the involucre is superficial, and placed at a distance from the margin. 
This character is often accompanied with a difference in habit; in Schizoloma the costa occupying 
the centre of the pinna, and the sorus being continued all round the margin. To this group or 
genus our plant evidently belongs, together with the Lindsea lanceolata of Mr. Brown, JL. ensifolia 
of this work, ScAizoloma cordatum of Gaudichaud, and |$. Guerinianum Gaud. To this latter, — 
a native of the Molucca Islands,—the present species has a very great affinity ; but it differs in its 
narrower and less oblique pinnz, in the nerves, which branch off from a central though slender 
costa, and are only once forked a little below their extremities; whereas im jS. Guerinianum there 
is a uniform reticulation : nor is the deep glossy and black colour of the stipes and rachis, which 
constitutes so remarkable a feature in our plant, at all noticed. 
Perhaps this group will scarcely be held distinct from Linds«a, when it is considered that in 
L. cultrata of this work (Tas. 144.) the involucre is as truly formed of a double involucre as in 
Sehizoloma ; notwithstanding which, the excentric costa, and the fructifications confined to the 
upper margin of the pinna, are characteristic of the true Zndse«. 
The slender costa and the nerves branching from it in our plant are not visible, unless the speci- 
men be held between the eye and the light; and then, in the dried state at least, the whole of the 
pinnz appear marked with small pellucid dots, arising from the reticulations.
