FLORA VITIENSIS. 189 
Natural Order Verbenacea, and closely related to Olerodendron and Oxera. Let me state the history of the 
genus. In 1862, I described, in the tenth volume of the ‘ Bonplandia,’ p. 249, a Olerodendron, from the 
Tongan or Friendly Islands, under the name of ©, Amicorum. Shortly afterwards, Asa Gray, travelling 
over the same ground, also came across this species, and had already given it exactly the same name when 
the ‘ Bonplandia’ reached him. On describing it in the Proceedings of the American Academy, vol. vi. p. 
50, he added another species (C. ovalifolium), from the Viti Islands, and pointed out that both agreed in 
their 4-lobed, almost regular calyx and corolla, and 4 stamens, at the same time proposing the sectional 
name Tetrathyranthus for these two Clerodendrons. At the beginning of the year 1865, an allied third 
species, collected by Mr. J. Storck in Viti, reached me, which also had a 4-lobed corolla and 4 stamens, but 
the calyx was almost invariably 2-lobed, the lower lobe frequently splitting into 2. This led to renewed 
examination. The calyx I found to be closed before anthesis and splitting, or rather tearing irregularly 
into 4, 8, or 2 lobes, when the corolla is forcibly pushed through a very narrow aperture at the apex, 
indicated by four very minute points,—one would hardly call them teeth, though they are in reality the 
teeth of the calyx. The splitting of the calyx is analogous to what we find in the genus Zecoma (as now 
circumscribed) and several genera of Hubignoniee; we have nothing like it in the genuine Cleroden- 
dron, and I think there can be no doubt that this set of plants must constitute a separate genus. I 
meant to have taken this view of the case in dealing with them in this place, and to have adopted A. Gray’s 
sectional name for the genus; but, as I find the species from Rockingham Bay to be a congener, and as a 
new name has actually been published, I adopted (Journ. of Bot. 1865, p. 258), Mueller’s name. 
In looking over the herbarium of the British Museum for congeners, I met with a plant having a calyx 
similar to my Furadaya Vitiensis, and provisionally named by R. Brown Vitex (?) macrophylla (foliis sim- 
plicibus integerrimis ovato-oblongis glabris costatis basi 2-glandulosis; caule arboreo), and discovered by 
Banks and Solander at Cape Grafton, east coast of New Holland. There is only one specimen extant, and 
an examination showed that the ovary is 5-celled, and that the carpellary leaves are involute, as in Clero- 
dendron and Faradaya. Solander gave to this plant the manuscript name Mphiélis simplicifolia, coupling 
it with another Verbenaceous plant (Vitex littoralis, A. Cunningh.), from New Zealand. As the former 
represents an entirely new generic type, Solander’s name might be adopted, since Schreber’s Hphiélis does 
not stand, being synonymous with Aublet’s datayba, and now regarded as a section of Ratonia. I should 
add that the only flower which could be examined had only four equal lobes of the corolla, whilst Solander 
mentions five; in estivation the external lobe overlaps the two placed next it, and these again overlapping 
the internal one. 
Epxtexis, Solander, mss. in Herb. Mus. Brit. excl. sp. Calyx ante anthesin clausus, demum irregula- 
riter 2-fidus, “ glaber, persistens, 3 lineas longus.” Corolla “irregularis (extus sericea); tubus cylindra- 
ceus, deorsum incurvus, longitudine calycis; faux magna, ventricosa, tubo duplo longior; limbus 5-parti- 
tus ; laciniz oblongsx, obtuse, patule, longitudine tubi, 2 superiores erectiuscule (intus nivese), 2 laterales 
divaricatz (colore superiorum); infima lacinia dependens, ceteris paulo longior (intus rubicunda, macula 
baseos magna lutea).” Stamina 4, “tubo longiora; anthere 2-lobe.” Ovarium 5-loculare, ovulis soli- 
 tariis. “Stylus filiformis, subulatis, inclinatus, corolla paulo longior. Stigma subulatum, acutum, re- 
flexum. Drupa oblongo-obovata, subtus 2-nata, obtusissima, (non penitus mutura magnitudine nucis Avel- 
lan#,) nux ovalis, 5-locularis, loculo centrali majore, nuclei oblongi solitarii.’"—Arbor Nove Hollandie orien- 
talis, foliis oppositis ovato-oblongis integerrimis costatis glabris, basi 2-glandulosis; floribus eymoso-pani- 
culatis axillaribus et terminalibus, albidis.—Seem. in ‘ Journal of Botany,’ 1865, p. 258. 
Species unica :— 
1, H. simplicifolia, Soland. mss. l.c.; Seem. in Journ. of Bot. 1. c.—Vitex (?) macrophylla, R. Brown, 
Prodr, p. 512.—Cape Grafton (Banks et Solander!). Dr. Mueller (Hragm, Phytogr. vol. vy. p. 72) observes 
with regard to this plant :—‘ Hphiélis, quam cl. Seemann sub generis dignitate adumbravit, fortassis V7- 
ticis genere haud removenda est, quia etiam Vitex Dalrympliana (eadem apparens ac V. macrophylla) pas- 
sim putamen 5-loculatum offert.”” Yet the calyx of Vitex macrophylla differs from that of all other species 
of Vitex, and seems to point to a generic diffefence.
