bus; laciuiis calycis setaceo-subulatis tubo brevissimo pluries longioribus; corolla hypocraterimor- 
pha (purpureo-czerulea), lobis ovalibus.—Bua Bay, Vanua Levu (U, 8. Expl. Exped.), Ovalau (See- 
mann! n. 351, ex parte). 
Frequently cultivated as an ornamental plant, together with the following, by the Huropean set- 
tlers in Fiji, The colour of the flowers of all I have seen is, as represented in the Plate, a purplish-blue, 
—not pure blue, as stated in Pickering’s notes, Iam inclined to think that this species gradually passes 
into EZ. insularum; indeed, both were distributed by me as one species, and under n. 351. H. lexiflorum 
is a half-shrub, 3-4 feet high, the lower leaves (one of which is represented (Fig. 1) in the background 
of the Plate) are sometimes 8-9 inches long, and 4-5 inches broad, whilst the leaves of the flowering 
branches are very much smaller, and more lanceolate in shape.

Orvo LXX. VERBENACEZ:. 
The most singular genera of Verbenacee occurring in tropical Polynesia are Faradaya and Oxera (both 
represented by several species), and the monotypic Wesogenes (NV. euphrasioides, DC. ; Myoporum euphra- 
sioides, Hook. et Arn.), In the Hawatian Islands we have three introduced species, viz. Verbena Bonarien- 
sis, Linn., collected in Oahu (Seemann! n, 1719! Barclay!); Stachytarpheta dichotoma, Vahl. (Maerae !), 
and some Lantana, which, from the scrap colleeted by Lay and Collie, was referred, with a mark of doubt, 
to L. annua, Linn, Lippia nodiflora, Rich (Zapania nodifiora, Lam,), has been found by Milne and M*Gil- 
livray in the Isle of Pines, off New Caledonia, by Forster in Tana, and by M‘Gillivray in Aneitum; and 
there can be little doubt that this common tropical weed occurs in Viti also.
