MR. MITTEN ON SOME NEW SPECIES OF MUSCI.

(JPhragmicoma.) 
L. excavata, Mitten. Ramis csespitosis dichotome ramosis ; foliis divaricatis imbricatis 
rotundatis, apice decurvis sinu parvo minute bidentatis, basi lobnlo oblongo unidentato 
complicato, amphigastriis appressis orbiculatis foliis dimidio minoribus, cellulis parvis 
rotundatis ; involucralibus conformibus, lobulis minoribus ; perianthio oblongo obtuso 
appresso, dorso concavo, ventre convexo, lgevi. 
Hab. On trees. Niger {Barter). 
In size and appearance resembling Omphalanthus g eminiflorus , Nees, but more nearly allied to Phrag- 
micoma Mackaii, Dumort. 
Tab. VI. fig. 24. 1. Plant (natural size); 2. portion of stem with leaves and amphigastria ; 3. perianth 
and •involucral leaves ; 4. transverse section of perianth. 
(Acrogonia.) 
L. astroidea, Mitten. Epiphylla, maculas astroideas formans ; foliis patentibus rhom- 
boideis integerrimis, angulo externo superiore acuminato, inferiore rotundato lobulo 
minuto inflexo ; cellulis heteromorphis, minoribus rotundatis interstitiis crassiusculis, 
majoribus 3-5-seriatim inordinatimve per folium dispositis, una majore semper in 
angulo inferiore partim a lobulo obtecta ; amphigastriis alternis ad basin in lacinias 
duas patentes subulatas divisis. 
Hab. On living leaves. Niger {Barter). 
Loosely appressed to the surface of the leaves^ in company with a species of Radula which, in so far as 
it can be judged of in a barren state, does not differ from R. Grevilleana, Taylor. This Lejeunia evidently 
belongs to the same curious section as L. Krausiana and a number of other tropical species, for the most 
part growing on the surface of leaves, and producing a turbinate pentagonal perianth, the angles being 
more or less produced into a horn-like point.

On the earth with a Riccia. Niger (Barter) . 
brevibus decurvis lacinulis sparsis vestitis, capsula inclusa 
Resembling Notothylas valvata, Sullivant (in < Memoirs of the American Academy of Arts and Sciences/ 
vol. iii. new series, pi. 4) ; but, in proportion to the size of the frond, the involucra are much smaller. The 
capsule is not protruded in the few specimens examined, but seems entirely enclosed in the involucre ; 
no trace of the suture or columella was visible. Anthoceros Brpn.MiL GnttsrViP. frmnd \ n fU
