the plant is sometimes obscurely blotched with purple ; the under side is less brightly-coloured and more even ; coral- 

 like processes yellowish (rising from the gonimical stratum). The apotheeia, however, perhaps afford the best marks, 

 as above indicated ; disc |-f- of an inch broad, or even more. Of the more rufous, more scrobiculated, and less divided 

 form, I have seen but indifferent specimens from New Zealand ; better examples abound in the beech-forests of 

 Tasmania. We add a figure of our b. pinnatifida, from a beautiful specimen of Mr. Colenso.— Plate CXXIII.

Very near the preceding, and perhaps not distinct from it ; and yet, after examining a considerable number of 

 specimens of this and the two preceding species, I have seldom found much difficulty in knowing to which I should 

 refer them ; the study of these intricate plants, however, must be left to colonial botanists. The pulvinate coralline 

 excrescences, the agreeable ochraceous hue, and especially the apotheeia, distinguish 8. D'Urvillei from its congeners. 

 " L. ochraceus, Menzies," without habitat, is the name attached to specimens in Sir W. J. Hooker's herbarium, and 

 in Aiton's (now my own). 8. D'Unittei occurs also in Chiloe, the Falklands, and Cape Horn. Dr. Hooker (with 

 whose views Dr. Montague accords doubtfully in a MS. note in Herb. Hook.) unites 8. endochrysa, Del. ! with 

 8. B' Urvillei, Del. ! ; but the former plant has the adult medullary stratum almost white, whereas in 8. D' Urvillei it 

 is, in every stage, of a full chrome-yellow ; there are, besides, other differences. I have not seen specimens from 

 New Zealand. 



b. Medullary stratum white in an adult state (the stratum towards the margins is slightly tinged with yellow).

 fluentibus viridi-tlavis (aliquando desunt), cyphellis minimis citrinis, apotlieciis submarginalibus extus sub-

A very variable plant, but in general readily recognized : perhaps some of Delise's species may be forms of 

 this. Fries (Lich. Europ.) says that the European plant cannot safely be distinguished from 8. aurata, but that 

 extra-European specimens are manifestly different. The European (at least the Scotch) plant agrees exactly with 

 that from New Zealand, and Delise says that Hooker's Scotch specimens are identical with those from the Sand- 

 wich Islands. If this species cannot be distinguished from 8. aurata, we must combine all the golden-cyphelled 

 Sticta; together, for no two are more distinct. In some European and New Zealand specimens the thallus is almost 

 or (in Sinclair's very fertile specimens) quite naked, in others nearly covered with green-yellow soredia. Cyphelte 

 sometimes almost obsolete.— The geographical range of this species is wide ; it occurs in England, Ireland, Scot- 

 land, France, Spain, the Canary Islands, Bourbon, Australia, Tasmania, Straits of Magellan, Falklands, Cape Horn, 

 west coast of South America, West Indies, Sandwich Islands, and the United States, and, if 8. gilva be the same, 

 at the Cape of Good Hope. This gives us as the range about 56° or 57° north and south. Dr. Hooker (Fl. Ant.) 

 names Invcrary as its northern limit, but I have gathered it at Arisaig, and also at Oban, both on the west coast
