36 BOTAXICAL BULLETIK. 



On the bark of trees, "Seaboard of South Carolina," Eavenel (1874). A small 

 species, of a yellowish color. Looks much like a small form of L. clypeata, which 

 it also resembles very closely in its opake leaf-cells ; but is readily separated from 

 it by its more convex leaves and bilobed amphigastria. 



Lejfunia Caroliniaxa, n. sp. — Caule perbrevi (1-2 lin.) flaccido; foliis rotun- 

 dis convexis squarroso-patentibus subverticalibus confertis sed laxe imbricantibus 

 in siccis margine apice valde decurvis, lobulo parvo subinflato, rete e cellulis 

 mediocribns poriformibus illis versus marginem sensira rainoribus intercalaribns 

 latissimis formato; amphigastriis rotundis bifidis; colesula pyriformi subcom-* 

 presso cxuinquangulato, angulis nudis : monoica; amentula masc. magna termin- 

 al! et laterali,— With Frullania Kunzei, var. in Aust. Hepat. Exsic. from Mobile, 

 Alabama, Sullivant (1845). About the size of L. Bavenelii, but of a subfuscous 

 color, and rather flaccid habit. 



Lejeunia l^te-fusca, n. sj).^C;tule repente 5-S lineas longo; foliis magis 

 minusve imbricatis latissime falcato-ovatis patentibus leniter convexis deplanatis 

 obtnsis (in medio fere usque ad basim cellulis 2 ve\ 3 multum ampliatis) maculatis, 

 lobulo minuto subovato valde inflate, reti basilari et centrali magno versus mar- 

 ginem sensim decrescenti, amphigastriis parvis orbiculatis bifidis, segmentis 

 erectis acutiusculis : colore lajte-fusca : csetera desunt. 



A few stems of this apparently very distinct species were found in a south- 

 ern collection, made by Mr. Sullivant in 1845; mixed with L. ovata, Tayl. and 

 L. Lcete-virens, N. & M. About the size of L. flava, (Swautz). Eeadily distinguish- 

 ed by its fuscous color, and by the 2-3 much enlarged cells in the center next to 

 tlie basal row. 



Lejeunia obcordata, n. sp, — Caule arete repens debili prolifero-ramoso brevi 

 tenui, foliis ratione eaulis magnis elliptico-rotundis subimbricatis patenti-subver- 

 tiealibus integerrimis convexis, lobulo mediocri inflexo turaidiusculo margine 

 parce dentato, rete magno discreto, amphigastriis nullis, perianthio parvinsculo 

 latissime obcordato bialatove compresso margine versus apicem crenulato ore min- 

 ute mammillato, involucri foliis quam perianthio dimidio brevioribus asquilobis 

 obovatis obcuneatisve integerrimis; inflorescentia monoica, amentulis numerosis 

 brevibus teetis. 



On some small fern, with Mastifiohryum palens, Mont. (3/. parvistipulum, Aust.), 

 Sandwich Islands. Well characterized by the perianth, which is compressed, 

 much expanded and broadly emarginate at the apex. 



FossoMBRONiA Macouni, 11. sp.—Cim\% incrassato brevissimo; foliis imbricatis 

 verticalibus incurvis valde cristato-undulatis et plicatis acute inciso-dentatis; co- 

 lesula parva cupulato-infnndibuliformi, margine crenato et subundulato; capsula 

 magna longiuscule exserta, elateribus crassiusculis bispiris longiusculis, sporis 

 parviudfulis subopacis densissime minutissime papillosis. 



Portage La Lochs, Lat. 57, Sept. 1875, Macoun. Readily distinguished by the 

 vertical and incurved leaves, short wide-mouthed colesula and minutely and close- 

 ly papillose spores. Colesula with the short base leafy-squamulose. 



Fossombroxia Wrightii, n. sp. — In adspectu F. mu/uloscc valde affinis sed dif- 

 fert: sporis valde opacis dense minute tuberculatis, elateribus longioribus angus- 

 tioribus, foliis magis acute angulatis, etc. On riparian rocks, Cuba, Wright. 



Fossombronia ^Cubana (Gott.) Aust.— Diflert ah F. angnlosa prosima; foliis 

 latioribus, sporis minutius reticulatis, elateribus angustioribus. — F. pusilla, var. 

 Cubana. Gottsche in Wright's Hepatica3' Cuhensas.—F.Texana, LiXDB.in Act. Soc. 

 Fenn. X, p. 533. Texas and Cuba, Wright. 



A few specimens of the Texas plant were distributed by me, in the Hepat. 

 Exsic, under No. 118 (F. longiseta). The Texas plant is about tlie size of ordinary 

 forms of F. any ulosa:, and the Cuban plant appears to difter from it (the Texas 

 plant) only in size, being 2 or 3 times larger.
