 or apiculate, areolation lax, costate to middle or beyond. — Bot. Centralbl. 

 44: 422. 1890. 



401. Neckera peterantha C. M. & Kindb. — Subspecies of N. oligo- 

 carpa: secondary stems nearly simple, about 1 dm. long, rigid and more 

 robust: leaves larger and more crowded, one branch of the costa prolonged 

 sometimes to middle: antheridia and archegonia very numerous: capsule 

 emergent. Mac. Cat. 162. — On rooks: Rocky Mountains, B. C. 



402. Neckera Donglasii Macounii Kindb. — Leaves less attenuate: cap- 

 sule turgid oval, completely exserted on long pedicel. Mac. Cat. 163. — 

 Hanging in long festoons from limbs of trees in shady woods: British 

 Columbia and Vancouver Island. 



403. Homalia Macounii C. M. & Kindb.— Very nearly allied to H. tri- 

 chomanoides : leaves longer, rather Ungulate, lowest basal cells yellowish; 

 perichsetial leaves more suddenly narrowed to very short acumen: segments 

 of peristome cleft between articulations. Mao. Cat. 163. — H. trichoman- 

 oides and H. obtusata Lesq. & James, Manual 285.^ — Canada; Newfound-

404. Pterigynandrum flliforme heteropterum Sch. — Plants morero-

 terum of this species. Mac. Cat. 165. — On rocks: British Columbia. 



406. Antitrichia Californica ambigna Ren. & Card. — Branches not
