FLORA OF NEW ZEALAND.

(see the excellent and learned remarks of Dr. Montague in the Annales des Sciences Nat. vol. xvi. ser. ii. p. 123 

 sqq.). — The species of the genus are found in the Canaries, the East and West Indies, throughout a great part of 

 South America, the Moluccas, Philippines, and the Ladrone Islands.

If Fee's figure belongs to this species, it represents a discoloured state different to anything that I have seen. 

 Specimens agreeing with the New Zealand form have been collected by Mr. Spruce at Para, and named by Dr. Mon- 

 tagne C. smaragdina, Pers. Solorina maculata, Tayl. ! in Herb. Hook., from the West Indies and the Philippines, 

 appears to be a form of this species. — Plate CXXIX. D. Fig. 1, plants, natural size; 2, portion of thallus, show-

Dr. Nylander's remark (Essai d'une Nouv. Class, des Lichens in Mem. Soc. Sc. Nat. Cherb. vol. ii. p. 15), that 

 this perhaps belongs to Coccocarpia, appears to us extremely just, and I have accordingly assigned it, with a marl 

 of doubt, to that genus. True apothecia unknown. 



Gen. VIII. STICTA, Ach. 



A large genus, principally inhabiting the southern hemisphere. The Lichens which compose it are among the 

 handsomest, and at the same time the most difficult and variable plants of the Order, and their study is especially 

 commended to the colonial botanist. I have endeavoured to revise the characters, but am much dissatisfied with 

 my efforts. Delise attempted a monograph of this genus, but his materials were quite insufficient ; his figures also 

 are oftentimes very indifferent. 



§ A. Cypliellm punctiform, bright golden-yellow. (Chrysosticta, Bad.) [The species of this section are nearly 

 allied, and very difficult to be defined by characters, which are more or less variable in all the Lichens 

 which compose it : they principally inhabit the southern hemisphere.] 

 a. Medullary stratum yellow. 



1. Sticta aurata, Ach. et Auctt.; thallo subcoriaceo lobato glaucescente passim lateritio rutilante 

 lobis sinuatis rotundatis non scroiiculatis marginibus (sterilibus) aurato-marginatis s. pulverulento-aureis, 

 subtus plus minus tomentoso ad centrum nigricante, apotheciis extus plus minus pubescentibus margina- 

 libus disco atro-purpureo planiusculo, margine (perfecto) lato citrino vel inflexo et obsolete — Fschw. Ic.

Hab. New Zealand, all travellers. Found fertile in Auckland by Dr. Sinclair. 



S. angustata of Delise (Stict. pp. 52, 598. t. 3. f. 7), from New Zealand, is not even a variety, being only a form 

 with rather longer lobes ; the black processes mentioned by him occur on both sides of the thallus in specimens from 

 Colenso and Sinclair; they appear to be accidental, and to result from age and decay. The S. aurata is subject to 

 considerable variation, even in its apothecia, which are sometimes almost smooth, sometimes a little hairy, but it is 

 usually known by its bright brick-red colour and pulverulent golden margins ; the thallus is not pitted in the manner 

 of the following species. It ranges from the equator to about 50° of latitude, north and south, fructifying princi- 

 pally within the tropics. I have seen specimens from Cornwall (Mr. Eagle), the Channel Islands, France, Corsica, 

 Canary Islands, St. Helena, the Cape, Van Diemen's Land, Brazil, and the West Indies. It has also been found in
