FLORA VITIENSIS. COT ED 
Hook. et Arn. Bot. Beech. p. 64), from the Society Islands (Lay and Collie !), Low Island (Capt. Cook !) 
Savage Island (Forster!), Fotuna (Milne!), Tobie Island (Barclay !), Tongan Islands (Nelson! Mathews! 
Harvey ), and New Hebrides (M‘Gillivray ), and a new allied genus from New Caledonia.* We have also 
the genus Kadua, confined to the Sandwich Islands, and of which A. Gray (Proceed. Amer. Acad. vol. iv.) 
enumerates ten species, viz. 1. K. centranthoides, Hook. et Arn. Bot. Beech. p. 85, collected by Nelson !, 
Macrae!, Nuttall!, and Menzies!; 2. K. glomerata, Hook. et Arn. Bot. Beech. p. 85; 3. K. cordata, Cham. 
et Schlecht. in Linnea, vol. iv. p. 160 (Wiegmannia glauca, Meyen, Reise, vol. ii. p. 189), which I have seen 
from Nuttall! and Menzies!; 4. K. Cookiana, Cham. et Schlecht. in Linnea, vol. iv. p. 158; 5. K. parvula, 
A. Gray, l.c, collected by D. Nelson!; 6. K. glaucifolia, A. Gray, l.e.; 7. K. Menziesiana, Cham. et 
Schlecht. in Linnea, vol. iv. p. 160 (Hedyotis coriacea, Smith; H. conostyla, Gaud.; Kadua Smithii, Hook. 
et Arn. Bot. Beech. p. 86), collected by Menzies!; 8. K. acuminata, Cham. et Schlecht. in Linnea, vol. iv. 
p. 163; 9. K. petiolata, A. Gray, l. c., and var. ovalifolia; and 10. K. grandis, A. Gray, l.c. Kadua affinis 
and K. Romanzoffiensis have been referred to the genus Gouldia in Eugardenice. 
VI. Hedyotis, Linn. Gen. n. 118; Endl. Gen. n. 3240 e. Calyx tubo ovato v. globoso, limbo 
4-fido, laciniis in fructu patentibus, sinu angusto separatis. Corolla breviter tubulosa, tubo vix lim- 
bum calycis zquante, fauce pilosa. Stamina exserta; filamenta brevia; anthere ovate. Ovarium 
inferum. Capsula subglobosa, nucamentacea, vertice breviter exserto styli basi persistente mucro- 
nata,indehiscens v. tardius dehiscens. Semina pauca, peltata.—Suffrutices, ramis procumbentibus 
divaricatis; foliis venoso-lineatis, stipulis ]-oo-setis; floribus axillaribus corymbosis v. capitatis, 
pedunculatis v. sessilibus.—Huhedyotis, Wight et Arn. Prodr. p. 411; A. Gray in Proceed. Amer. : 
Acad. vol. iv. 
Hedyotis gracilis, DC. Prodr. vol. iv. p. 419, from New Caledonia (Labillardiére), which must look 
very much like Oldenlandia tenuifolia, and H. Laperousii, DC. l. e. p. 420, from Vanikoro (Lesson), have 
not been met with in Viti, and must be re-examined now that the limits of Hedyotis and allied genera are 
more clearly defined. | 
l. H. Cratzeogonum, Spreng. Pug. vol. ii. p. 35; caule tereti glabro articulato; foliis lanceo- 
latis acuminatis venosis; stipulis setoso-laceris; floribus sessilibus glomerato-verticillatis.—DC. 
Prodr. vol. iv. p. 420; Rumph. Amb. vol. vi. p. 25. t. 10.—A common weed throughout Viti (See- 
mann! n. 235; Harvey! Milne!). Also collected in the Solomon group (Milne!). - 
My plant has not the leaves seabrous, as those of the Java plant are described to be, but otherwise it 
does not seem to differ from it. It is closely allied to H. venosa, Korth., but differs in shape of leaf and 
general glabrousness. 
VII. Oldenlandia, Linn. Gen. n. 154; Endl. Gen. n. 3240 g. Calyx tubo ovato v. globoso, 
limbo 4-dentato v. -fido, lobis v. dentibus in fructu erectis. Corolla breviter tubulosa, infundibuli- 
formis v. subrotata, fauce glabra v. villosa. Stamina exserta; filamenta brevia; anthere ovatze v. 
orbiculate. Ovarium inferum v. semiinferum, 2-loculare. Ovula in placentis dissepimento utrin- 
que adnatis, oo, horizontalia, anatropa. Capsula ovato-subglobosa, apice breviter exserto, rimula 
* Tarea (gen. nov. Hedyotidearum), Seem. Calyx tubo oblongo, limbo 5-lobo, lobis insequalibus lan- 
ceolatis. Corolla pentagono-infundibuliformis, tubo brevi, limbo 5-fido, lobis 3-angularibus acutis, zstiva- 
tione plicato-valvatis. Stamina 5, ima basi coroll: insert: ; filamenta elongata; antherz lineares. Ovarium 
oblongum, 2-loeulare, loculis oo-ovulatis, ovulis suborbieulagibus compressis in utroque loculo 2-seriatis 
adscendentibus imbricatis, stylo elongato; stigma indivisum. Capsula inequilatere pentagono-oblonga. 
Cet. ign. Frutex glaber, inermis ; foliis oppositis, obovatis breviter acuminatis v. obtusis; pedunculis axil- 
laribus 3-5-fidis; floribus magnis, pulchris, albis.—Species unica, T. portlandioides, Seem. mss. Kanala, 
New Caledonia (Vieillard! n. 890). Corolla 2 inches long, with 5 prominent ribs between the lobes. 
Stamens and style slightly exserted ; filaments hairy towards the base, and merely adhering to the corolla 
at the point of insertion; anthers slightly twisted in a dried state. This new genus l have named in 
honour of Mr. Ralph Tate, F.G.S., author of a Florà of Belfast and an Enumeration of Shetland Plants. 
It is closely related to Bikkia and Portlandia. From the former it differs by its pentamerous flowers, 
from the latter in having adscending (not horizontal) ovules, overlapping each other. On account of its 
beauty, it is fully deserving the attention of the horticulturist.
