C. (Eucheilanthes) bullosa— Eu-cheil-anth'-es ; bnl-lo'-sa (blistered or 

 puckered), Kunze. 



A greenhouse species, native of South Hindostan and the l^eilgherries, 

 where, according to Beddome, it is very common. Its fronds, 6in. to 9in. 

 long and 2in. to Sin. broad, are borne on densely-tufted stalks 4in. to Sin. 

 long, of a dark chestnut-brown colour, shghtly woolly below, and clothed with 

 spear-shaped scales their whole length. They are furnished with numerous 

 leaflets disposed in opposite pairs, the lower ones IJin. apart, IJin. long, |m. 

 broad, and spear-shaped. The pinnules (leafits) on the lower side are the 

 largest, and are cut down nearly to the midrib into numerous Imear-oblong 

 segments of a somewhat leathery texture. The abundant sori (spore masses) 

 are covered by involucres of a pale brown colouv— Hooker, Species Filicum,

C. (Adiantopsis) californica — Ad-i-ant-op'-sis ; cal-if-or'-nic-a (Cah- 

 fornian), Mettenius. 

 This exceedingly pretty Fern, commonly known in E'orth America under 

 the name of " Cahfornian Lip Fern," is found in moist and shady ravines and 

 canons, and known only from the coast ranges of the Southern part of 

 California and from Sonora, in Mexico. Its elegant fronds are borne on 

 densely-tufted, erect stalks about 6in. long and of a glossy nature, and proceed 

 from a short-creeping rootstock that is very cha% with rigid, narrow scales 

 of a pecuhar dark brown colour ; they are deltoid (in the shape of the Greek 

 delta, A), about 3in. each way, and quadripinnatifid (four times divided half-way 

 to the midrib). The leafits of the lower side, which are much larger than 

 the others, are cut down to the midrib into numerous segments, which are 

 again very sharply cut nearly to the centre. The sori (spore masses), which 

 are roundish, and disposed from two to six to a segment, are usually placed 

 at the base of the sinuses (depressions) at the ends of single veinlets. Eaton, 

 in his excellent work on North American Ferns, says that by its general 

 habit this extremely pretty and delicate little Fern reminds one of the 

 rare Cystopteris montana, but that its fronds are of firmer texture and 

 stiU more finely divided. He also adds that : " There is no other North 

 American Fern which resembles it, even slightly"; that C. Schimjjeri of 

 Kunze, from Abyssinia, and C. incisa, equally of Kunze, from Brazil, are its
