FLORA VITIENSIS. 191

rulis; stigmatis cruribus inzqualibus acutis.—Gmelina Vitiensis, Seem., Mission to Viti, p. 440.— 
Viti, locality not specified (Milne !). : 
Milne collected only one specimen of this singular plant, all the leaves of which are truly simple; 
but it may be that the species has also compound leaves, like most of its congeners. The unequal lobes of 
the stigma point to a certain relationship with Gmelina, but all the other characters are those of a genuine 
Vitex. Petioles 6-12 lines long. Blade of leaf from 3-5 inches long, and 131—243 inches broad. Corolla 2- 
labiate, the upper lip 2-lobed, the lower 3-lobed. Calyx, corolla, and filaments covered with down. Anthers 
ovate. Ovary 4-celled. Ripe fruit unknown. 
EXPLANATION. oF Prate XLV., representing Vitex Vitiensis, from specimens collected by Milne and a

open; 4, stamen; 5, calyx and pistil; 6, pistil; 7, cross-section of ovary,—all magnified. 
Orpo LXXI. LABIATZE. 
Four genera of Polynesian Lebiatz have as yet not been met with in Viti, viz. Sphacele, Coleus, Phyllo- 
stegia, and Stenogyne. Sphacele is represented by S. hastata, A. Gray, in the Sandwich Islands (U. S. Expl. 
Exped.); Coleus by C. scutellarioides, Benth. (Ocimum scutellarioides, Linn.) in Tana (Forster! M‘Gilli- 
“vray !) and Eromanga (M‘Gillivray !) ; the two other genera are confined to the Hawaiian Islands, and they 
have recently been revised by Asa Gray. Of Phyllostegia we have, 1, P. vestita, Benth. (P. dentata, Benth.), 
2, P. grandiflora, Benth. (Prasium macrophyllum, Gaud. ?) ; 3, P. brevidens, A. Gray, et var. (P) ambigua ; 
4, P. glabra, Benth. (P. Macraei et Chamissonis of Benth., Prasium glabrum, Gaud.) ; 5, P. hirsuta, Benth. ; 
6, P. parviflora, Benth., var. a. Gaudichaudi (P. parviflora, Benth.), var. B. glabriuscula (P. macrophylla, 
Benth. presertim pl. Macraei), and var. y. mollis (P. mollis, Benth.) ; 7, P. stachyoides, A, Gray ; 8, P. cla- 
vata, Benth.; 9, P. racemosa, Benth.; 10, P. haplostachya, A. Gray, and var. P. leptostachya; 11, P. trun- 
cata, A. Gray; and 12, P. floribunda, Benth. Of Stenogyne we have, 1, S. macrantha, Benth.; 2, S. rotun- 
difolia, A. Gray ; 8, S. cordata, Benth. ; 4, S. sessilis, Benth. ; 5, S. calaminthoides, A. Gray ; 6, S. scrophu- 
larioides, Benth., and var. B (S. Nelsoni, Benth., Pheopsis montana, Nutt.) ; 7, S. rugosa, Benth. ; 8, S. 
angustifolia, &. Gray ; 9, S. microphylla, Benth. ; 10, S. crenata, A. Gray; and 11, S. diffusa, A. Gray.
