Hook, et Arn. Bot, Beech. p. 64), from the Society Islands (Lay and ollie !), Low Island (Capt. Cook!) 
Sayage Island (Forster!), Fotuna (Milne!), Tobie Island (Barelay!), Tongan Islands (Nelson! Mathews! 
Harvey !), and New Hebrides (M‘Gillivray !), and a new allied genus from New Caledonia.* We have also 
the genus Aadua, confined to the Sandwich Islands, and of which A. Gray (Proceed. Amer. Acad. vol. iv.) 
enumerates ten species, viz. 1. J. centranthoides, Hook. et Aru, Bot. Beech. p. 85, collected by Nelson !, 
Macrae!, Nuttall!, and Menzies!; 2, K. glomerata, Hook. et Arn. Bot. Beech, p. 85; 3. A. cordata, Cham. 
et Schlecht. in Linnea, vol. iv. p. 160 (Wiegmannia glauca, Meyen, Reise, vol. ii, p. 139), which I have seen 
from Nuttall! and Menzies!; 4. K. Oookiana, Cham. et Schlecht. in Linnea, vol, iv. p. 158; 5. K. parvula, 
A. Gray, lc, collected by D. Nelson!; 6. K. glaucifolia, A, Gray, le.; 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 Linnawa, vol. iv. 
p. 163; 9. A. petiolata, A, Gray, |.¢., and var. ovalifolia; and 10. A. grandis, A. Gray, l.e. Kadua affinis 
and K. Romanzoffiensis have been referred to the genus Gouldia in Eugardenicae. 
VI. Hedyotis, Linn. Gen, n, 118; BWndl. Gen, n. 3240 e. Calyx tubo ovato v. globoso, limbo 
4.fido, laciniis in fructu patentibus, simu angusto separatis. Corolla breviter tubulosa, tubo vix lim- 
bum calycis eequante, fauce pilosa. Stamina exserta; filamenta brevia; anthers ovate. Ovarium 
inferum, Capsula subglobosa, nucamentacea, vertice breviter cxserto styli basi persistente mucro- 
nata, indehiscens vy. tardius dehiscens, Semina pauca, peltata.—Suffrutices, ramis procumbentibus 
divaricatis; foliis venoso-lineatis, stipulis ]-so-setis; floribus axillaribus corymbosis y. capitatis, 
pedunculatis y. sessilibus.—Luhedyotis, Wight et Arn. Prodr. p. 411; A. Gray in Proceed. Amer, 
Acad, vol. iv, 
fedyotis gracilis, DC. Prodr, vol. iy. p. 419, from New Caledonia (Labillardiére), which must look 
very much like Oldenlandia tenuifolia, and H. Laperousii, DC. 1.c. p. 420, from Vanikoro (Lesson), have 
not been met with in Viti, and must be re-examined now that the limits of Hedyotts and allied genera are 
more clearly defined. 
1, H, Cratzogonum, Spreng. Pug. vol. ii. p. 35; caule tereti glabro articulato; folis lanceo- 
latis acuminatis venosis; stipulis setoso-laceris; floribus sessilibus glomerato-yerticillatis.—DC, 
Prodr, vol. ivy. p. 420; Rumph. Amb. vol. vi. p. 25. t. 10.—A common weed throughout Viti (See- 
mann! n. 255; Harvey! Milne!). Also collected in the Solomon group (Milue!), 
My plant has not the leaves scabrous, 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. 32409. 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; antherz ovate v, 
orbiculatze. Ovarium inferum v, semiinferum, 2-loculare, Ovula in placentis dissepimento utrin- 
que adnatis, co, horizontalia, anatropa. Capsula ovato-subglobosa, apice breviter exserto, rimula 
* Tarea (gen, nov. Hedyotidearum), Seem, Calyx tubo oblongo, limbo 5-lobo, lobis inequalibus Jan- 
eeolatis, Corolla pentagono-infundibuliformis, tubo brevi, limbo 5-tido, lobis 3-angularibus acutis, eestiva- 
tione plicato-valvatis. Stamina 5, ima basi corollie inserte ; filamenta elongata; anthere lineares. Ovariui 
oblongum, 2-loculare, loculis c0-ovulatis, ovulis suborbicularibus compressis in utroque loculo 2-seriatis 
adscendentibus imbricatis, stylo elongato; stigma indivisam, Capsula inzquilatere pentagono-oblonga. 
Cet. ign. Frutex glaber, inermis; foliis oppositis, obovatis breviter acuminatis v. obtusis; pedunculis axil- 
laribus 8—5-fidis; floribus magnis, pulchris, albis.—Species unica, 7. 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 mew genus 1 have named in 
honour of Mr, Ralph Tate, F.G.5., author of a Flora of Belfast and an Enumeration of Shetland Plants. 
It is closely related to Bithia and Portlandia. Fyrom the former it differs by its pentamerous flowers, 
from the latter in haying adseending (uot horizontal) ovules, overlapping each other. On account of its 
beauty, it is fully deserving the attention of the horticulturist.
