BRUCHIA'CE^E. A family of inoper- 

 culate Acrocarpous Mosses, gregarious or 

 Cfespitose and terrestrial, in which the fruit- 

 stalks sometimes appear lateral, through 

 arising from innovations. The stems dwarf, 

 either simple or branched by innovations ; 

 the leaves lanceolate or awl-shaped from a 

 more or less oval base, composed of paren- 

 chymatous cells, larger and sometimes lax 

 at the base of the leaf, smaller and squarish 

 toward the apex, and furnished with a flat- 

 tened broad nerve (fig. 49), and standing up 

 like bristles ; the perichsetial leaves broader 

 at the base and sheathing j all of firm mem- 

 branous character, shining and smooth. 

 Capsules oval or globose, mostly straight- 

 beaked (fig. 50). British genera : 



Archidinm. Calyptra completely en- 

 closing the (globose) capsule, bursting above. 

 Inflorescence monoecious, bud-shaped. 



Astomum. Calyptra dimidiate. Capsule 

 equal. Inflorescence either monoecious, 

 gemmif orm and axillary, or with the anthe- 

 ridia and archegones together. 



BRU'CHUS, Linn. A genus of Coleo- 

 pterous Insects. 



B. pisi is a common small beetle ; black, 

 mottled with white. The larva feeds upon 

 peas. Several other species.

BRYA'CE^E. A family of operculate 

 Mosses, acrocarpous, or by innovation pleu- 

 rocarpous, with lan- 

 ceolate, oval, round, Fig. 81. 

 or spathulate leaves, 

 composed of cells pa- 

 rallelograrnmic below, 

 rhomboidal - paren- 

 chymatous above, 

 more or less dense, 

 with much chloro- 

 phyll or a persistent 

 primordial utricle, or 

 at length empty, very 

 smooth. Capsule more Mielichoferia nitida . 

 or less Pear-shaped, Teethfromther . 8tome 



Clavate, Oval or cylin- Magnified 150 diameters. 



drical, with a hemi- 

 spherical or conical operculum, erect, nod- 

 ding or pendulous. External peristome, 



when present, soft, lamellose, internal 

 membranous. British genera : 



Mielichoferia. Calyptra conical-dimi- 

 diate, split at the side. Peristoine wanting 

 or simple, then of sixteen equidistant, fili- 

 form, flattish, articulated pale teeth, some- 

 times placed on a short, sulcate, reticulate 

 basilar membrane (fig. 81). Capsule late- 

 ral, with a double annulus. 



Orthodontium. Calyptra smallish, hood- 

 shaped, fugacious. Peristome arising below 

 the orifice of the capsule, double j external : 

 of sixteen lanceolate-subulate teeth, like 

 those in Bryum j when dry, deflexed below 

 the orifice of the capsule, when moistened, 

 erect; internal: cilia alternating with the 

 external teeth, half as long or about equal, 

 filiform, from a short, somewhat keeled 

 membrane. Capsule annulate or exannu- 

 late, with a longish collum. 



Bryum. Calyptra dimidiate, smallish, 

 hood-shaped. Peristome double (fig. 82) ;

Bryum intermedium. 



A portion of the peristome. 

 Magnified 150 diameters. 



external of sixteen lanceolate, soft, yel- 

 lowish equidistant teeth, flat on the back 

 and transversely trabeculated, with a flexu- 

 ous longitudinal line in the middle, lamel- 

 late within, hygroscopic; internal a large 

 delicate membrane with sixteen keels, pro- 

 duced into more or less perfect lanceolate 

 teeth, often with intermediate cilia, some- 

 times without. Capsules mostly annu- 

 late.

 eyes near the hind angles of the cephalo-
