obtnso plus minus decurvis, rete e cellulis minutis subrotundis margine 

 sinuatis, illis ad basiu valde majoiibus obscuris, intersticiis latis subobscuris 

 instructo ; auricula tecta cucullata valde compressa parva subovali cauli ad- 

 proxiniata ; ampbigastriis magnis orbiculatis planis apice integris vel rare 

 subemarginatis margine leniter repandis ; perianthio oblongo subexserto, dorso 

 ))lano convexove, ventre (carina valde compressa) unicarinato ; involucri foliis 

 semicordato-ovatis acutis integerrimis vel 5-ubundulato-repandis, lobulo 

 longiori lineari-setaceo canaliculate, ampbigastriis elongato-lanceolatis pro- 

 funde bifidis subintegerrimis. 



Nepal. Herb. Snlliv. 



Readily distinguished from F. iiitenristipula, Nees, by the fertile flower con- 

 taining but a single pistil, by the orbicular ampbigastria plane on the margins, 

 by the cucullate, suboval, compressed auricle, &c. 



FOSSOMBRONIA CrISTULA, Aust. 



F. minuta, albescens; caule perbrevi (1 — 2 lineas longo) arete repenti 

 furcatim vel fastigialim diviso, radicibus plerumque purpureis terram aflfixo ; 

 foliis angulariter lobulatis subintegrisve quadratis vel obovato-rotundis sub- 

 ditformibus plerumque basi subaugustatis atque apice valde undulato-crispatis; 

 perianthio fere ut in F.pusiUa ; involucro nullo ? capsulain pedicello brevissimo 

 immersa; sporis pallido-fuscis parce snbgrosseque tuberculatis circa 1-600 — 

 1-700 unc. metientibus ; elateribus delicatissimis hyalinis unicellularibus 

 brevibus crassiusculis plus minus difformibus, fibro tenuissimo pallido-fusco 

 annulari et spirali [plervmque partini annulari ac partim cpirali) depictis. — Hep. 

 Bor. Amer. Exsic. ined., No. 121. 



On damp sand, associated with Dicranum. cerviculatum and Jiingermannia 

 crfinidala, in an unfrequented path, near Batsto, New Jersey, (Oct., 18G8). 



Remarkable for its small size, and very delicate, often somewhat branched 

 elaters of more or less variable shapes (much as in the Anthocerotem), and with 

 the liingle fibre usually partly annular and partly spiral in the same example! 

 Antheridia few and large, oval or roundish obovate, nearly sessile on the back 

 of the stem. Pistillidia (about 20) somewhat crowded towards the apex of the 

 stem, above the antheridia, and just below the perianth, and partially immersed 

 in the stem ; not involucrate, or very imperfectly so. 



AXDROCRYPHIA LONGISETA. 



Fossombronia longiseta, Austin, MSS, 1864. 



A. dioica ; caule suberecto vel depresso 3 — 4 lin. longo e dorso prolifero- 

 ramoso, radicibus purpureis terram affingenti ; foliis pallidis subimbricatis sub- 

 horizontalibus subquadratis lobis plerumque obtusis undulato-lobulatis subin- 

 tegrisve inferioribus nonnullis parvis, involucralibus plerumque valde 

 majoribus subflabelliformibus basi nonnullo attenutttis ac in tubulum cum 

 caulis apice confluentibus ; perianthio plerumque magno campanulato varie 

 modo ineiso vel subintegro ; pedicello longiusculo (4 — 6 lin. alt.) tenui basi 

 in caulis apice longe incluso ; capsula irregulariter lacera magna calyptram 

 (et nonnullo perianthium) implenenti ; sporis subangularibus subuigris valde 

 muricatis ; elateribus longiusculis bispiris. 



€n the ground among mosses. California, Bolander; Texas, Wright. 



A variable species. The perianth often smallish, but frequently very large ; 

 sometimes divided to the base into 2 — 3 flabelliform divisions and again nearly 

 entire, the smaller ones undulate and crisped at the mouth, the larger ones 

 often nearly entire and nearly plane at the mouth. The upper leaves are more 

 or less involucrate, with their bases often costa-form, and more or less united 

 into a tube and confluent into the stem. Pistillidia quite numerous, at first 

 naked and scattered on the back of the stem (as in Fossombronia). Stem 

 frequently' bearing a descending tuber underneath the perianth, and usually 

 considerably eitending beyond it. On the prostrate stems the leaves are often
