1. Racopilum australe, Hook. fil. et Wils. ; dioicum, caule repente radiculoso tomentoso rage sub- 

 pmnatim ramoso, foliis lateralibus disticlie patulis siccitate crispato-tortuosis oblongo-ovatis apice serrulatis 

 nervo peUucido excurrente longe cuspidatis intermediis paullo minoribus ovato-acummatis surrectis, seta 

 crassa breviuscula, capsula oblonga cernua arcuata sulcata basi strumulosa, operculo brevirostri, calyptra 

 pilosa basi campaimlata. (Tab. XCII. Fig. 7.) 



Hab. Northern and Middle Islands, in various localities ; common at the roots of trees. 

 A Tasmanian Moss.— Leaves in the principal specimens yellowish, in others deep green, much crisped and undu- 

 lated when dry. Seta very thick, triangular when dry, about i inch long. Capsule at first pale yellowish-olive, when 

 older deep red, with an operculum half its own length. Calyptra pale yellow, very hairy, inflated below, not dimi- 

 diate. Teeth red, large. Inner peristome with cilia.— In Colenso's specimen the male flowers are nidulant on the 

 fertile plant; but specimens from Dr. Sinclair are truly dioicous.— PiATE XCII. Fig. 7:— 1, plant, natural size; 

 2, young capsule and calyptra ; 3, mature capsule and operculum ; 4, 5, leaves :— all magnified. 



2. Eacopilum cristatum, Hook. fil. et Wils. ; monoicum?, caule repente, foliis lateralibus disticlie 

 patulis siccitate conniventibus ovali-oblongis obtnsiusculis apice serrulatis nervo concolore excurrente 

 cuspidatis intermediis cordato-acuminatis dnplo minoribus, seta longiore gracili, capsula arcuata sulcata, 

 operculo brevirostri, calyptra subulata dimidiata parce pilosa, peristomii dentibus dorso scabris.— B. 

 gymnanthe, Wils. MSS: (Tab. XCII. Kg. 5.) 



Hab. Northern Island : Tehawera forests, Colenso. 



A native of Norfolk Island, Australia, Juan Fernandez? Guadeloupe? East Indies? Mauritius?— Leaves more 

 obtuse than in the preceding, not tortuous when dry, the cuspidate points shorter, areolae larger. Seta about f inch 

 long, not angular. Male flowers nidulant.— Probably Hypmim mucronatum, P. Beauv., from Africa, is a robust form 

 of this, but the original specimen in Herb. Hook, is barren. The specimens from Juan Fernandez and Guadeloupe 

 have the capsule more elongated (B. leptocarpum, Wils. MSS.).— Plate XCII. Fig. 5 :— 1, plant, natural size; 2 

 capsule ; 3, operculum ; I, calyptra ; B, portion of branch and leaves :— all magnified. 



3. Racopilum robudum, Hook. fil. et Wils. ; monoicum?, caule repente, foliis uniformibus confertis 

 patentibus siccitate lateribus complicato-involutis cordato-ovatis acuminatis excurrentinerviis apice subser- 

 ratis, seta crassa longiuscula, capsula arcuato-cernua sulcata, calyptra pilosa mitrajformi (Tab XCII 

 Fig. 6.) 



Hab. Northern Island : forests of Teliautotara, Colenso. 



A larger species than either of the preceding. Leaves yellowish or pale green, more crowded, tapering gradually 

 to an acute point ; nerve much excurrent. Seta longer than in R. australe. Calyptra less hairy.— B. spectaMle, E. 

 et Hornsch., differs from this in the strongly serrated unequal leaves and dimidiate subulate calyptra. R tomen- 

 tosum, Swartz, differs from this and all the preceding in the truly monoicous inflorescence and naked dimidiate 

 calyptra.— Plate XCII. Fig. 6 .— 1, plant, natural size ; 2, capsule; 3, calyptra; 4, 5, leaves :— all magnified. 



Tribe XXIII. HooKERiACEiE. 



Gen. LXIII. HOOKERIA, Smith. 



Peristomium duplex : exterius, dentes 16, lanceolato-subulati, acuminata', incurvi, intus trabeculati, 



dorso costis prominentibus plus minus distantibus biliratis : interius, membrana plicata, in processus 16 



carinatos raro ciliis interpositis fissa. Calyptra mitrasformis. Capsula cernua, ovata, longius pedunculata. 



Caulis repens vel prostratus, vage ramosus. Rami plerumque compressi. Folia online •?- vel -2- disposita 



mpms disticlie imhricata vel complanata, lateralia obliquata, areolis majusculis, rhomhoideis vel hexagonis. 



The genus Eookeria, as limited in 'Bryologia Europsea,' not only excludes all the New Zealand species, but also
