FLORA VITIENSIS. 183 
eo-floris; bracteis amplis; calyce pedicello longiori tubuloso fere zequaliter 5-dentato persistente 
fructum ovatum includente.—Taviuni (Seemann! n, 281). 
A remarkable species, of which the corollas are unknown, The very shaggy petioles, 3 or 4 inches 
long; the blade of the leaf conspicuously veiny. Fructiferous calyx 7 to 10 lines long, cylindraceous or 
tubular-cyathiform, glabrate, longer than the included even full-grown fruit. 
10. C. dolichocarpa, A. Gray, 1. c.; frutescens; ramis gracilibus junioribus cum petiolis pedun- 
culis calycibusque pilis longis rufescentibus multiseptatis (modo C. Milnei) barbatis; foliis oppositis 
subsequalibus lanceolato-oblongis acuminatis denticulatis supra hispidulis subtus breviter fulvo- 
pubescentibus; pedunculis axillaribus 1-floris; calyce longe tubuloso fructu cylindrico siliqueeformi 
(14-2-pollicari) acuto + breyiore, sero deciduo.—Woods of Sandal-wood or Bua Bay and Nady, 
Vanua Levu (U. 8. Expl. Exped., Milne!). 
“ Bvidently allied to O. Wilnei, by the pubescence, tubular calyx, ete. The latter is made out from 
vestiges which remain upon one side of one of the fruits, showing that it attains fully an inch in length. 
Yet it is exceeded by the singularly elongated fruit, which, except in form, resembles that of other species 
of Cyrtandra, 7. e, is corticate, probably fleshy when fresh, but juiceless and indebiscent. The stamens must 
determine whether its relationship is with Bieldia or Whitia (the latter probably no good genus); but 
other Polynesian species exhibit a similar, only less elongated fruit.”—Asa Gray.

Orpo LXIX, ACANTHACEA. 
Besides the species enumerated or alluded to below, this Natural Order is represented in tropical 
Polynesia by :— 
1. Dilivaria ilicifolia, Juss. (Acanthus ilicifolius, Linn.), which has been found in New Caledonia 
(W. Anderson !) and Tana (Forster !). ; 
2. Ruellia reptans, Forst. Prodr. n. 242, and Icon. (ined.) t, 181,—a plant with white flowers, appa- 
rently different from Dipteracanthus lanceolatus, to which the Linnean Ruellia reptans is referred by Nees, 
and eollected in Tana, Eromanga, and Aneitum, New Hebrides (orster!, W. Anderson!, Barclay !, 
M‘Gillivray !). 
3. Dicliptera pubescens, Juss, (Dianthera cerulea, Forst. Prodr. n. 14, et Icon. (ined.) t. 9), from 
the Isle of Pines and Botanist’s Island off New Caledonia (Forster!, W. Anderson !, M‘Gillivray !) 
4. Dicliptera clavata, Juss. (Dianthera clavata, Forst. Prodr. n. 15, t. 10), from the Society Islands 
(Banks and Solander!, Nelson !), and haying white flowers, subulate bracts, aud spathulate involucral 
bracts. ; ; 
5. Dicliptera frondosa, Juss. (Dianthera floribuada, Sol. Prim. Fl. Ins, Pacif. (ined.) p, 203), from 
Tahiti (Forster!, Wiles and Smith!), and of which Solander says: “ Suffrutex Dianthere bracteata, Sol., 
simillimus quoad caulem, ramos, folia, et modum florendi, immo flores et fructum ; differt_ autem bracteis 
angulatis, cuneiformibus, stipulis subdivisionum pedunculi subulatis. A Dianthera velata differt pedunculis 
numerosis seu pluries subdivisis et angustia bractearum. Stipule sub singula divisura pedunculorum 
bine, opposite, subulate. Bractee caneitormes, obtuse, basi attenuate, integra, altera minore. Capsule 
obcordatza, basi attenuates. Dianthera velata, bracteata, Hloribunda, et leta valde aflines. ; 
6. Dicliptera velata, Seem, (Dianthera velata, Sol. Prim. Fl, Ins. Pacif. p, 201; Parkins. Drawings 
of Tahit. Plants t. 8 (ined.)), Society Islands (Banks and Solander !). Suffrutex 3-pedalis, ramosus. Cawles 
erecti, glabri, obtuse tetragont ; lateralibus alternis suleatis, alteris carinatis ; carma obtusa. Rami bra- 
chiati, supra genicula tumidi sea substantia molli farcti, unde in speciminibus exsiccatis ibidem coarctatt. 
Folia caulina et ramea, opposita, petiolata, patentia, oyato-elliptica, acuminata, obsolete crenata, sinubus 
erenarum puneto glandulaceo albido notatis, glabra, tenuia, venosa; venis remotis apicem yersus flexis ;
