bidentata, laciniis acuminatis aeutis porreetis, margine postico 

 persaepe parvo dente munito. Cellulse marginales 0*017, reliquse 

 0*025 mm., trigonis distinctis. Amphigastria bifida, laciniis 



setaceis rnaxime divaricatis, sinu levissimo discretis, extus dente 

 plus minus longo munitis, ad basin utroque latere lacinia retro- 

 spectante optime hastatim setacea. Cetera desunt. 



It is most difficult nowadays to publish a new Lophocolea or 

 Chiloscyphus, the old descriptions being so short as to make it 

 often impossible to recognize the plants ; it is much to be wished 

 that some English botanist would go to Kew and give us detailed 

 descriptions and good figures of all species contained in that vast 

 collection. These two genera want it more than any other genus 

 of Hepaticse. 



14. Lophocolea tkiangulifolia, Steph., sp. n. (PL XXVII. 



fig. 11.) 



Sterilis, pallida, in cortice longe lateque repens. Caulis 4-5 cm. 



longus vage ramosus. Folia dense imbricate, plano-disticha, 

 opposita, basi antica libera, triangulij brmia, e basi latissima 

 versus apicem maxime angustata (apice sextuplo angustiora) ipso 

 apice breviter emarginata, sinu obliquo plus minus angusto, den- 

 tibus insequalibus (ventrali minore) breviter acuminatis acutis, 

 versus apicem plant ce spectantibus. Cellulso marginales 0*025, 

 reliquie 0*035 mm., angulis haud incrassatis nisi ad basin foliorum. 

 Amphigastria majuscula cauli accumbentia utroque latere foliis 



limbo angusto connata, usque ad basin fere quadrifida, laciniis 

 lanceolato-subulatis, divaricatis. 



A well-distinguished species; the leaves are so broad at the 

 base, that each covers the base of the next two above and below, 

 four in all. The only species to be compared is Lophocolea tas- 

 manica, Mitten, the leaves of which are more slender and the 

 stipules of a very different shape. 



15. Pallaviclsia connivess, Steph. — Symphyogyna conni- 

 vens, Colenso, Trans. JV. Z. Inst. xx. p. 254. 



Dioica, minor, flavescens, gregarie crescens. Caulis (*. e. frondis 

 pars inferior exalatus) e caudice repente erectus, 2 cm. longus, 

 fusco-purpureus, fasciculo brunneo cellularum elongatarum per- 

 cursus, apice anguste alatus abrupte in frondem dilatatus. Frons 

 reniformis valde carnosa, marginibus erectis conniventibus vel 

 involutis, ccsta bis vel ter dichotoma ubique lamina tenera con- 

 nata, apice solum inter costas emarginata et plicatc-erispula,
