Yar. y. PARVIFOLIA : foliis minoribus ellipticis (1^ - 2-poll.) ; pe- 

 dunculis paucifloris nunc elongatis, fructifex'is petiolo bis longioribus. 

 Feejee Islands. 



The other species of the collection are A. stellata, from the same 

 groups of islands, and from Tahiti and Eimeo ; A. scandens, only from 

 the latter ; and the Sandwichian A. olivcBformis, Gaud., to which must 

 be referred A. sulcata, Hook. & Arn., and may be referred a small- 

 leaved variety, myrtillifolia. 



Cerbera Odollam, Gsertn., from Tahiti, &c. (where it is not 

 indigenous), must be Forster's and Guillemin's G. Manghas. 



Cerbera lactaria, Hamilton ((7. Odollam of Dr. Seemann's 

 collection) comes from Tongatabu and the Feejee Islands. So also 

 does 



OCHROSIA PARVIFLORA, Hensl. {Cerbera, Forst.) : it is named 0. 

 elliptica by Seemann, and perhaps it is Labillardiere's plant. To the 

 lamented Prof. Henslow's account may be added, that the ovaries are 

 not really united except at their apices, that the ovules are eight, four 

 on'each margin of the suture, amphitropous, the micropyle superior. 



OcHROSiA Sandwicensis, A. DC. is not in the collection of the 

 Expedition, but is in Remy's collection ; the flower-buds almost an 

 inch long, the narrow lobes of the corolla rather longer than the tube, 

 which is glabrous within. Ovules 3 or 4 in each ovary. Seeds pel- 

 tate on each face of the nearly complete false partition, exalbuminous ? 

 Radicle inferior ! 



Ltonsia l^vis (sp. nov.) : glabra ; foliis ovatis subcordatis acu- 

 tato-acuminatis ; calycis lobis triangularibus acutis brevibus ; corolla 

 fere glabra fauce tantum annulatim barbata ; squamis nectarii dis- 

 cretis glaberrimis ovarium sub^quantibus ; capsula cylindrica leviter 

 bisulcata. — Feejee Islands. This is probably the Echites scahra ? of 

 Dr. Seemann's collection, no. 315, of which I have seen no specimen ; 

 but it differs from the New Caledonian plant (judging from Labillar- 

 diere's figure) in the pointed leaves, the general smoothness, smaller 

 and acute calyx-lobes, glabrous nectary and ovary, terete capsule, and 

 nearly glabrous corolla, within having a bearded ring instead of five 

 vertical bearded lines. Of his Lyonsia, Brown well remarked that it 

 is Parsonsice nimis affinis. The best distinction is to be found in the 

 thickish lobes of the corolla, essentially or nearly valvate in aestiva- 

 tion ; so that here, rather than in Parsonsia, belongs P. ventricosa of 

 F. MuUer.
