68 HEPATIC^. [Anthoceros. 



2-lobed, the upper lobe roundish, acute, the lower rotundato- 

 saccate ; stipules roundish, plane, emarginate ; fruit terminal ; 

 calyx obcordate, tuberculated, triangular. Linn. Sp. pi. p. 

 1600. Hook. Br. Jung. t. 5. 



On trees, also on rocks ; very common. 



75. J. Tamarisci, LINN. Stems prostrate ; leaves unequally 

 2-lobed, the upper lobe ovato-rotundate, the lower minute, 

 obovate, saccate ; stipules subquadrate, emarginate, their mar- 

 gins revolute ; fruit on short terminal branches ; calyx obovate, 

 smooth, triangular. Linn. sp. pL p. 1600. Hook. Br. Jung. 

 t. 6. 



On bushes, trees, and rocks ; common. The stipules are often 

 twice as wide as the stems. The middle and upper leaves of the 

 branch are frequently apiculated, and sometimes even the inferior like- 

 wise. 



7. ANTHOCEROS, Linn. 



Male flowers aggregate, immersed in the frond. Capsule linear, 

 2-valved, having a central filament, and issuing out of a tu- 

 bular prolongation of the superior membrane of the frond. 



1. A. punctatus, LINN. Frond subrotundate, stellato-lobate, 

 the lobes nerveless broad, obovate, their margins somewhat 

 elevated, waved, subcrenate. Linn. sp. pi. p. 1 606. Dill. Muse. 

 t. 68, /. 1, 2. Schmid. Ic. t. 19. Eng. Bot. t. 1538. Muse. Brit.

On clay or soil bare of other vegetation, as in fallow fields, sides of 

 ditches ; very common : flowering throughout the year in the County 

 of Kerry. That there are two distinct species on the Continent of 

 Europe, it may be rash to deny, as all Continental botanists seem 

 agreed on their existence. In Ireland I have seen but a single species, 

 sometimes exactly represented by the Dillenian figure 1, at other 

 times by 2 ; and not unfrequently intermediate specimens not quite 

 referable to one or the other are to be found. This genus has hitherto 

 been arranged among the calyptrati ; which, I fear, was only acci- 

 dentally true, as the real calyptra seems to have escaped observation. 

 It is true Hedwig has delineated and described in his Theoria, ed. of 

 l7VS,pag. 189, what would appear to be decisive on the subject ; he 

 says, " elevatur etiam monticu)us conicus, cujus summitati insidet opus 

 " fuscum e tenerrimis filamentis ad calyptrse formam compositum, brevi 

 " stylisco instructum. Emergit postea inde corpusculum cylindrico- 

 " conicum, corniculum referens, tec.tum in cacumine dicto stylisco mi- 

 " traeformi, qui diutius ibi, punctuli fusci specie ad nudum oculum, 

 " moram nectere solet, nisi tempestatum injuriis inde deturbetur. Non 

 " latuisse etiam Schmidelium hanc singularem partem constat e numero 

 " 8vo. suae descriptionis." I have repeatedly, at different seasons of 

 the year, at different periods of maturity, and for many years, in vain 

 looked for such a structure in our Irish species. I can hardly suppose 

 that Hedwig was deceived, although even in the foregoing extract 

 there is some confusion in first placing the calyptra on the top of the 

 conical elevation of the upper surface of the frond, and afterwards on
