FLORA OF NEW ZEALAND.

lanceolato obtuso, perianthio terminali elongato cylindraceo compresso bilabiato labiis subtruncatis integer- 

 rimis.— Lond. Joum. Bot. 1844, p. 566. 0. L. et N. Syn. Hep. p. 261. 

 Hab. Northern Island : Bay of Islands, /. D. H. 



Sordide luteo-viridis. Caulk pollicaris, ramosus. Folia laxe imbricata, e cellulis minutissimis rotundatis re- 

 motis areolata, margine incrassato subcorneo fusoa. Lobulus oblique ovatus, fere erectus, cauli appressus. Perian- 

 thium compressum, inferne angustatum, utroque latere marginatum. 



Easily distinguished from all its congeners by the thickened margin of its leaves, which is most evident in 

 the dry state. Dr. Taylor states the stems to be three inches long ; in our specimens they are about one inch long, 

 and agree nearly in size and habit with R. 



Gen. XVIII. MADOTHECA, Dumort.

Hab. Abundant throughout the Islands, Menzies, etc. 



Found as far south as Lord Auckland's Group. The differences in appearance of the varieties of this species 

 are great, but when a sufficient number of specimens are examined, they will be found gradually passing into each 

 other. The largest state has branches nearly a foot in length, and with the central parts of its stipules bossed out- 

 wards, forming an umbo, which is completely lost in the common states. 



Gen. XIX. LEJEUNIA, Goltsohe et JAndenberg. 



1 . Lejeunia Stepliensoniana, Mitten ; caule dichotome ramoso, foliis imbricatis oblongo-ovatis acutis 

 integerrimis margine ventrali incurvis et basi in lobulum parvum dentatum abeunte, amphigastriis obovatis 

 subtruncatis denticulatis. (Tab. CII. Eg. 3.) 



Hab. Northern Island : a fragment picked from Mosses gathered in ravines near Wellington by Mr. 

 W. Stephenson (Hb. Mitten). 



Olivacea, sesquipollicaris. Folia vel explanata vel apicibus incurvis et involutis. Amphigastria crenato-denti- 

 culata, lateribus paullulo recurvis. 



In size and appearance this closely resembles L. scutellata; in its denticulate stipules it is more nearly allied to 

 L. spatulistipa, Nees, and L. comosa, Ldbg., species from Java and Penang ; but its more remote leaves give the 

 branches a different appearance. The genera Thgsananthus, Phragmicoma, Omphalanthus, and at least the smaller 

 species of Ptycfamthus, are here considered Lejeunia, for the characters upon which they have been separated are those 

 which both in Lejeunia and Frullania are subject to wide variation : thus F. cylindrica is as much entitled to generic 

 distinction as Omplialanthus, for the smoothness or plication of the perianth in Frullania (which it seems impossible 

 to break up into smaller natural genera) has a corresponding series in Lejeunia understood as above ; indeed there 

 appears nothing but the greater size of the plants to keep Bryopteris and the larger species of PtgcJianthus from 

 falling into Lejeunia.— Plate CII. Fig. 3 :— 1, a stem, natural size; 2, a portion of the same with leaves and sti- 

 pule : —both magnified. 



2. Lejeunia scutellata, Mitten ; caule casspitoso adscendente dichotomo, surculis erectis, foliis imbricatis 

 subpatentibus convexis oblongis integerrimis apice recurvis basi sinuato-complicatis lobulis rotundis involu- 

 tis, amphigastriis subimbricatis rotundatis, perianthio axillari oblongo angulis integerrimis, foliis involucrali- 

 bus immersis subintegerrimis ovato-lanceolatis lobulis lanceolatis, amphigastriis floralibus elongato-obovatis 

 emarginato-bifidis.— Thysananthus scutellatus, HooJc.fil. et Tayl. Lond. Joum. Bot. 1846, p. 383. G. L 

 et N. Syn. Hep. p. 739. (Tab. OIL Kg. 4.)
