Ilypole-jns] I. — filices. 57 



pinnules J in. long, ovate ; secondary pinnules deejjly cut in several 

 small sharply-toothed lobes ; costas and under surface of the frond 

 slightly hairy. Sori small, roundish, on the lobes of the pinnules, 

 usually solitary on the lobes. 



Distribution. — Confined to New Zealand, where it is wide-spread, 

 frequenting open and hilly ground, often up to considerable eleva- 

 tions. In the North Island it is local, having been gathered on the 

 Ruahine Mountains and at Wangarei in the far north. 



In the South Island it is common along the whole eastern side of 

 the main ranges, but is very local on the west. 



This is a hardy fern, and thrives very readily under cultivation. 

 Its fronds — like those of several species of Pteris, &c. — are cut down 

 ■every winter, and come up fresh and green in the spring. 



Genus XIV.— CHEILANTHES,* S^varts. (PL II. fig. 5.) 



Rhizome stout, short and scaly. Fronds rather small, seldom 

 exceeding 1 ft. in height, tufted, rigid, erect, 2- or 3-pinnatifid, 

 veins all free. Sori at first small, subglobose, terminal or nearly so 

 on the veins, afterwards more or less confluent. Involucres formed 

 from the rellexed margin of the fronds, not quite continuous. 



Fronds deltoid ; pinnules \-l in. long, 



ascending 1. C. tenuifoKa. 



Fronds oblong-lanceolate; pinnules J- J in. 



long 2. C. sieberi. 



1. C. tenuifolia, Swartz. 



Rhizome covered with silky scales. Stipes tufted, 4-8 in. long, 

 •erect, wiry, fiexuous, purplish-black, polished, slightly hairy below. 

 Fronds 4-8 in. long, 3-4 in. broad, deltoid, S-jjinnatifid ; rachis 

 narrowly winged above, or naked, polished; pinnae in G-12 nearly 

 opposite or alternate pairs, ascending at an acute angle with the 

 rachis, the lowest 2-4 in. long, 1-2 in. broad, deltoid ; pinnules 

 ■deltoid or oblong, cut down to the rachis into deltoid or oblong, 

 •entire or irregularly lobed segments. Sori often continuous, cover- 

 ing the back of the pinnule and projecting beyond its margin ; 

 involucres more or less toothed. 



Distribution. — Throughout India, S.E. China, Malay Peninsula 

 -and Archipelago, Polynesia, Australia, Tasmania and Uruguay 

 (S. America). 



Rare in New Zealand, having been collected only in the Hawke's 

 Bay district in the North Island ; and at Lyttelton Harbour, Banks' 

 Peninsula, Lake Hawea and mountains about Queenstown in the 

 South Island. 



* Gr. Oheilos, a lip ; aiitlios, a flower, from the fructification on the margins 

 •of the frond.
