Rubiacea.} SOCIETY ISLANDS.

breviores ad medium bi-bracteati: Bractea rotundato-ovatse. Calycis tubus subrotundus: Limbus brevis, 4- 

 dentatus. Corolla (nobis non visa, at, secundum Collie) infundibuliformis, 4-loba, cum antheris 4 in faucem 

 sessilibus. Fructus junior bilocularis, polyspermus : maturus (sec. Collie) baccatus. 



This appears to us to belong decidedly to Petesia, as described by De Candolle, (Prodr. v. 4. p. 395.) It 

 cannot be the P. carnea, Forst. (Eumachia, DC), since that has only one seed in each cell of the fruit; and 

 it differs from most Rubiacea in its carnose leaves. 



1. Morinda citrifolia. Linn. — De Cand. Prodr. v. 4. p. 446. 



1. Timonius Forsteri; foliis obovatis, floribus axillaribus, masculis cymosis, hermaphro- 

 ditis solitariis, bacca subrotunda. De Cand. Prodr. v. 4. p. 461. — Erithalis polygama, a . 

 " Forst. Prodr. 1. n. 101." — Bumeya Forsteri. Cham, et ScMecht. 



In the Linnsea, the parts of the flower are described as quinary or quaternary. In our specimens, their 

 arrangement is sometimes senary.

 Hab. Whitsunday Island. (Mr. Lay.) 



1. Canthium lucidum; ramis inermibus, foliis breviter petiolatis ellipticis obtusis, basi 

 paululum attenuatis coriaceis supra lucidis subtus pallidis, cymis pedunculatis axillaribus, 

 bacca subglobosa. 



This plant has the calyx 4— 5-toothed, the corolla 4~5-lobed, and either 4 or 5 stamens. The character 

 accords with that of the genus in De Candolle's Prodr. v. 4. p. 473, and our species appears closely allied 

 both to C. glabrum and C. nitens. 



1. Chiococca barbata; erecta, foliis ovalibus basi acutis in petiolum brevissimum attenu- 

 atis apice acuminatis obtusis, pedunculis axillaribus solitariis uni-trifloris, corolla fauce 

 barbata. (Tab. XIV.)—" Forst. Prodr. 1. p. 96." De Cand. Prodr. v. 4. p. 483. 



Caulis subarboreus; ramis erectis, elongatis, glabris, teretibus. Folia digitalia, ovalia, membranaceo- 

 coriacea, subnitida, integerrima, subtus pallida, basi in petiolum perbrevem attenuata, apice acuminata, obtusa. 

 Stipula late cordato-ovata?, mucronato-acuminabe, rigida?. Pedunculi axillares, triflori, supremi uniflori: 

 Pedicelli bracteis brevissimis suffulti. Calyx quinquedentatus, dentibus brevibus acutis. Corolla infundi- 

 buliformis, 5-fida, ore barbato, laciniis ovatis, demum reflexis. Stamina paululum exserta. Stylus filiformis. 

 Stigma capitatum, obscure bilobum. Fructus: Drvpa magnitudine Nucis Avellaiwe, obcordata: nucibus 

 duabus monospermis. 



This appears to us to be the C. barbata of Forster. Yet it is described as having the leaves acute at both 

 extremities, and the peduncles single-flowered. De Candolle says that in habit this differs from the genus, 

 but he was only acquainted with the plant in an indifferent state.

2. Chiococca odorata; foliis lato-ovalibus subcoriaceis obtusissimis basi acutis in petio- 

 lum brevem decurrentibus, pedunculis axillaribus solitariis 3-4-floris, corolla fauce barbata. 

 — Coffaea odorata. " Forst. Prodr. 1. ». 94." ? 



Hab. Elizabeth Island.— Of this we have seen no fruit ; but the flowers and the general habit of the 

 plant are so very similar to those of the preceding, that we cannot separate it from the genus Chiococca. 

 The flowers are described as fragrant, and smelling like cowslips ; and it may be the Coffeea odorata of 

 Forster, but the description given of that plant is too brief to enable us to judge with certainty respecting it.
