358 elater (pl. elateres; eleters) —- a differentiated elongate cell, dead at maturity and 
normally with one to three helicoidal wall thickenings, found interspersed among the 
spore mass in most liverwort capsules; function: to break up and subsequently help 
disperse the spores (cf. pseudoelaters) [(323, g266, 892, 370]. 
359 elaterocyte — diploid cell within most liverwort and all hornwort capsules that 
differentiates into an elater (liverworts) or undergoes a few mitotic divisions to form a 
pseudoelater (hornworts) [f324, g267, s371]. 
360 elaterophore — a tuft or brush-like cluster of elater-like cells attached to either the base or 
apex of a capsule in a few liverworts; e.g., Riccardia, Pellia [325, g268, s372, 910]. 
361 elimbate — lacking a border; referring to leaves without strongly differentiated marginal 
celis [f515, g1037, s373]. 
362 ellipsoidal -- an oval solid [f326, 340, g269, s374]. 
363 elliptical — oblong with convex sides or ends [f327, g270, s375]. 
364 elongate — stretched out; e.g., linear [f26, 1064, s36, 376]. 
365 emarginate — broad, shallowly notched apex, deeper than retuse; e.g., Tortula [[328, g118, 
s3 
366 duos — the developing sporophyte phase normally generated from a zygote; in most 
bryophytes it consists of capsule, seta and foot initials [(330, g271, s379]. 
367 embryogenesis — the process of embryo development [f329, g272, s378]. 
368 emergent — partially exposed, referring to capsules or perianths only partly projecting 
beyond the tips of perichaetial leaves (cf. exserted, immersed) [f331, g457, s380]. 
369 endemic - limited to a single country or floristic area [f332, g273, s381]. 
370 endogenous - originating from internal rather than superficial cells or tissues; €.g., 
endogenous branches in some liverworts [(333, g274, s382]. 
371 endogenous intercalary — in liverworts, endogenous brenches arising from internodal 
stem regions [f543, g275, s970]. 
372 endohyalocyst — see hyalocyst [f334, g276, s383]. 
373 endohydric — having water transport essentially internal (cf. exohydric, mesohydric) [£355, 
374 endosporic (etidojerid) — the occurrence of one or more mitotic divisions within the 
of the spore wall to produce a multicellular protonema prior to spore wall 
rupture; e.g., Pellia, Dicnemon, Drummondia (cf. precocious) [f336, g278, s385]. 
375 endostome — the inner circle of a diplolepidous peristome, formed from contiguous 
periclinal wall-pairs of the primary and inner peristomial layers; typically a weak 
membranous structure consisting of a basal membrane b nd cilia. The 
endostome is homologous with the haplolepidous peristome [f337, g280, s386 
376 endothecium (pl. endothecia) — in bryophytes the inner part of the embryonic ees € 
Bives rise to all tissue interior to the outer spore sac. In Sphagnum and hornworts the 
endothecium only produces the columella (see amphithecium) [£338, g281, s387]. 
377 enervate — lacking a costa (cf. cere [f339, g852, s388]. 
378 ensiform — sword-shaped [f344, s397]. 
m pom 7 Without teeth, more or vs smooth on the margin; e g., leaves, thalli [345, £362: 
380 - -lived [f354, g61 s368, 5

381 bcd —theu upper initial ( wes * l
