 ZONARIA SINCLAIRII, Rook. JU. et Ham. 



Gen. Char. Root woolly. Frond flat, ribless, coriaceo-menibranaceous, 

 flabelliform, entire or vertically nmltifid ; the surface-cellules set in 

 longitudinal lines, radiating from the base of the segments. Fructifi- 

 cation : spores superficial, collected in spot-like sori, and mixed with 

 jointed paranemata. — Zonaria {Ag.), from ^wvrj, a zone or girdle; 

 because the frond, in many species, is marked with distant, concen- 

 tric lines. 



Radix stuposa. Frons plana, ecostata, coriaceo-membranacea,flabellata, Integra 

 v. multisecta ; cellulis supeificialibus in tineas longitudinales e basi lacinia- 

 rum radiantes ordinatis. Fried., sporce in soros maculiformes collects, para- 

 nematibus artictdatis stipatce. 



Zonaria Sinclairii; erect; stem terete, slender, woolly, much branched; 

 branches ending in narrow, wedge-shaped, basally attenuated, entire 

 or inciso-pinnatifid segments; sori oblong or linear, longitudinally 

 extending.

 elongatis in laminas anguste cuneatas basi attenuatas integras v. inciso-pinnatifi- 

 das abeuntibus ; soris oblongis linearibusve.

Descr. Root an expanded, broadly conical disc, covered with rigid, woolly, rust- 

 coloured hairs. Fronds tufted, erect, 2-4 inches high, with a flabelliform 

 outline, much branched. Stem and branches filiform, clothed with ferrugi- 

 nous tomentum, the latter setaceous, the former as thick as whipcord. 

 Branches, or their divisions, ending in vertical, narrow wedge-shaped la- 

 mina?, an inch to an inch and a half in length, and from \-\ inch wide at the 

 top, tapering at base, rounded, inclining to fan-shaped at the apex, which 

 is pale and semi-transparent, like horn, smooth, except where joined to the 

 branch, marked with obsolete transverse concentric zones, and finely striated 

 with longitudinal radiating lines. Two forms of frond occur, often in the 

 same tide-pools. In one (as our fig. 1), the laminae are quite simple and 

 perfectly entire at the sides ; in the other (fig. 2), the sides of the laminae 

 are more or less deeply lacerated in an oblique direction, ascending from a
