leaves, according to the figure, of a reuiform outline ; and probably 

 they are connected on the dorsal side, although on this point the 

 description is silent. The genus Lindigia was changed to Lin- 

 digina, Gottsche, " Prodr. PL Novo-Granatensis " in ' Ann. des Sc. 

 Nat/ 4nie serie, toni. i. 1864, Lindigia having been employed by 

 Hatnpe for some species of Meteoria, of which the Leskia acicu- 



lata, Taylor, is one. 



Z. scariosa in the * Synopsis ' is described with leaves " lato ro- 

 tundis," and in the 'Mexikanske Levermosser ' L, Lielmanniana 

 with leaves " obovatis cauli oblique adcretis ;" amongst further par- 

 ticulars below, they are " ovato-rotunda obovatave." Fortunately 

 there is a good figure of this species, exhibiting the leaves to be 

 really reniform, as in L. scariosa] or identification, from the de- 

 scription alone, would be in either case almost impossible. 



[Fragments have been seen of another species of the Lethocolea 

 group from the Cape of Good Hope, which may be the same as 

 the i. prostrata from Tristan d'Acunha. 



In the ' Handbook of the Tlora of New Zealand,' in ignorance 



* 



of Lindigina, LetJiocoIea was employed to designate some species 

 which agree with those referred by Gottsche himself to Lindigina, 

 yet in some respects diflTer from it if i. Liehnantiiana is taken as 

 the typical species, and also if its leaves are opposite and com- 

 bined; it would then, with L. scariosa and L, renijolia and some 

 other Mexican and South- American species, all with opposite and 

 combined leaves on the dorsal side, form a group with a more lax 

 areolation than is observable in the Lethocolea Drummondii and 

 L. concinna of the Taamanian flora, and also in the Lindigina 

 Oranatensis, Gottsche, " Prodr. Tl. N.-Granat." in 'Ann. des Sc. 

 Nat.' 5me ser. torn. i. 1864, 137, in all which the leaves are alter- 

 nate and of more dense substance. 



In a Mexican species belonging to the opposite-leaved section 

 oi Lindigina the male inflorescence consists of anthcridia in the 

 saccate bases of cauline leaves as in LopTiocoJea.
