Forst., and which varies considerably in the shape of the leaves (in 

 one form lanceolate-oblong and more or less acuminate), was gathered 

 at the Tonga or Friendly, and the Samoan or Navigators' Islands, 

 with the nascent leaves and shoots fulvous-hirsute, as described ; while 

 the Feejean collection has apparently the same species with the young 

 parts glabrous. To this last may probably be referred all three Mabce 

 of Dr. Seemann's collection. 



Maba Sandwicensis (A. DC.) : foliis lato-lanceolatis oblongis sen 

 ovalibus coriaceis pallidis venuloso-reticulatis glabratis, novellis cum 

 ramulis floribusque sericeo-pilosis ; floribus in axillis subsessilibus, 



masculis 15-17-andris calyce alte trifido, foemineis ; fructu ovali 



calyce breviter trilobo stipato. — Ludit foliis nunc utrinque acutiusculis 

 vel obtusiusculis, nunc basi rotundatis, nunc utrinque rotundatis basi 

 retusis, sesquipoll. ad 4-poll. — Oahu, Hawaii. 



Sapotacece. 



Sersalisia glabra (sp. nov.) : foliis obovato-oblongis basi attenu- 

 atis coriaceis glabris, venis reticulatis ; pedicellis in axillis fasciculatis 

 petiolo duplo longioribus ; corolla calyce subsericeo paullo longiori 

 campanulata 5-fida glabra, lobis rotundatis filamenta sterilia subulata 

 multo superantibus stylo gracili requilongis. — Woolongong, New South 

 Wales. There is a specimen of this in the Hookerian herbarium from 

 Mr. Backhouse ; also a related one from Fraser, which is perhaps the 

 S. laurifolia of Richard, and one from Cunningham, named Mimusops 

 myrsinoides, may be the same thing. 



Isonandra ? RiCHii (sp. nov.) : undique glabra ; foliis chartaceis 

 obovatis apice rotundatis nunc retusis basi acutis ; pedicelUs calyce 

 4-fido plusduplo longioribus ; filamentis barbatis. Bassia retusa, Rich, 

 in herb. — Tongatabu. Only a single and not very perfect corolla is 

 extant from which to determine the genus. As that appears to be 

 four-cleft, like the calyx, and with a fertile stamen in the sinuses, as 

 w^ell as one before each lobe, and there are no appendages, I refer the 

 plant to Isonandra, notwithstanding the bearded filaments. 



Bassia Amicorum (sp. nov.) : foliis obovatis seu ovalibus retusis 

 glabris viridibus (3 — 6-poll.) ; pedicellis elongatis ; corolla glabra 6- 

 partita (semipollicari) calyce 6-nervi plusduplo longiore ; staminibus 

 18 ; filamentis subulato-filiformibus antheris lineari-sagittatis cuspidatis 

 ajquilongis. — Tongatabu, on the shore. Mr. Rich supposed this to be 

 Forster's B. obovata, from Tanna ; but that has the leaves less veiny,
