chaud's figure of the anther of V. penduliflorum. Striking as are the 

 very reticulated and spinulosely-serrate, Barberry-like leaves, these are 

 not diagnostic of the species, since the teeth are not prolonged in the 

 plant figured by Gaudichaud, and, on the other hand, this foliage is 

 imitated in some specimens from Mouna Kea, which have roundish 

 calyx-lobes and no basal cusp to the anthers, therefore belonging to 

 the var. dentatum of the preceding species. 



Nuttall's genus Metagonia is equivalent to Klotzsch's sections Ma- 

 cropelma, Disterigma, Neurodesia, and a part of Vitis-Idcea, including a 

 variety of species, which, however distributed, cannot be properly sep- 

 arated from Vaccinium. The dorsal awns are not always erect in the 

 section Macropelma ; in our specimens of V. cereum, from Tahiti, they 

 are sometimes (perhaps abnormally) reflexed. 



Our collection has nothing answering to the Epigynium ? Vitiense, 

 Seem., no. 284 of his Feejee collection. 



Gaultheria (Dipltcosia) Luzonica (sp. nov.) : foliis ovalibus 

 utrinque acuminatis supra glabris subtus ramisque novellis parce stri- 

 goso-hispidis ; pedunculis fasciculatis petiolo longioribus ; bracteolis 

 connatis orbiculatis. — Luzon, in the Majaijai Mountains ; in fruit.

The pollen in all the following species of Cyathodes is four-lobed, in 

 the manner of Ericacece, to a suborder of which the Epacridece should 

 be reduced. 



Cyathodes Pomar^e (sp. nov.): fruticosa, erecta; foliis subpatulis 

 oblongo-linearibus mucronatis margine integerrimis (novellis prope api- 

 cem ciliolatis) subtus glaucis multinervibus, nervis extimis subramosis; 

 sepalis bracteolisque rotundatis subciliolatis ; corollne tubo calycem bis 

 superante, lobis imberbibus ; stylo subulato ovario .5 - 7-loculari triplo 

 longiore. — Society Islands, on the mountains of Tahiti. Dr. Picker- 

 ing in his notes does not distinguish this from the plant gathered on 

 Eimeo, which is not well to be discriminated fi'om the following species ; 

 while this has larger flowers as well as leaves, the tube of the corolla 

 exserted beyond the calyx, and a longer style. Mr. Brown long ago 

 alluded to a Tahitian Cyathodes (Prodr. p. 539), but it seems to have 

 been unnoticed from the time of Cook's voyages down to our own 

 Expedition. The two brought by our collectors appear not to be 

 uncommon ; so it is remarkable that nothing of the kind was collected 

 by Bertero or Moerenhout ; at least none is mentioned in Guillemin's
