Tribe XVII. Neckerace^;. 

 Gen. LI. NECKERA, Bruch et Schimp. 



Peristomium duplex : exterius, dentes 16, lanceolato-subulati, intus trabeculati, vix hygroscopici : in- 

 ternes, processus "16, e membrana angusta carinato-plicata hyalina, cum dentibus alternantes. Calyptra 

 cucullata, nuda. Capsula ovalis, sequalis, erecta, mollis, exannulata, immersa vel exserta. — Eolia octofariam 

 cauli inserta, distiche complanata, oiliqua, transverse undulata, nitida, tenuissime areolata. Canlis repens. 

 Surculi erecti, pinnatim ramosi. 



1. N eckera pennaia, Hedw. ; monoica, foliis ovato-lanceolatis acuminatis apice serrulatis undulatis 

 subenerviis, pericheetialibus internis elongato-lanceplatis acuminatis, capsula immersa, operculo brevirostri, 

 ealyptra parva vix infra operculum producta. — Hedw. Muse. Frond, v. 3. t. 19. Bruch et Schimp., Bryol.

Hab. Northern Island : trunks of trees ; Wangarei and Wairau, Colenso. 



Very rarely found in Scotland, Ireland, and throughout Europe ; abundant in North and South America, East 

 Indies, etc. 



2. Neckera laevigata, Hook. fil. et Wils. ; monoica, surculo pinnatim ramoso, foliis ovatis obtusis in- 

 tegerrimis dorso lsevigatis convexis (haud undulatis) nervo brevi, perichsetialibus convolutis lanceolatis, cap- 

 sula exserta brevipedicellata. (Tab. LXXXVIII. Fig. 3.) 



Hab. Middle Island : Banks' Peninsula and Port Cooper, Lyall. 



One inch in height. Leaves more loosely imbricated, full green, firm ; nerve ceasing below the middle. Cap- 

 sule just exserted, on a very short pedicel. — Allied to TV. Jamesoni, Taylor ; but that has the leaves acute and undu- 

 lated. — Plate LXXXVIII. Pig. 3 : — 1, plant, natural size; 2, portion of stem, perichsetium, and capsule ; 3, peri- 

 chsetium and capsule; 4, 5, leaves : — all but fig. 1. magnified. 



Gen. LIE TRACHYLOMA, Bridel. 



Peristomium duplex : exterius, dentes 16, angusti, snbnodulosi, duri : interim, cilia totidem cum iis 

 alternantia, e membrana brevi orta, angusta, carinata, nodulosa. Calyptra cuculliformis. Capsula erecta, 

 oblonga, subsequalis, curvula, exannulata. — Folia subenervia, complanata. Habitus dendroideus, caule 

 repenle, surculo superne pinnatim ramoso. 



The generic name is founded upon a mistaken view of the inner peristome : rpayyi, rough, and A<o/xa, margin (of 

 the cilia). The peristome, especially as to the structure of the teeth, is that of Neckera ; but the leaves, though 

 complanate, are not oblique, and the habit is more dendroid. The cilia of the inner peristome are not at all lacu- 

 nose, hence not in accordance with Climacium of Bruch and Schimper; and the pinnate ramification is also at 

 variance with the definition of that genus, and in the peristome it differs from Isothecium. — For the present it is con- 

 sidered inexpedient to change the name given by Bridel. 



1. Trachyloma planifolium, Hook.; dioicum, surculo erecto pinnatim ramoso, ramis complanatis, 

 foliis distiche imbricatis erecto-patentibus ovatis apice serratis subenerviis, capsula erecta subcylindrica, oper- 

 culo conico-subulato. — Bridel, Bryol. Univ. t. 2. p. 278. Neckera planifolia, Rook. Muse. Exot. t. 23
