bus; laciniis calycis setaceo-subulatis tubo brevissimo pluries longioribus; corolla hypocraterimor- 
pha (purpureo-czrulea), lobis ovalibus.— Bua Bay, Vanua Levu (U. S. Expl. Exped.), Ovalau (See- 
mann ! n. 351, ex parte). 
Frequently cultivated as an ornamental plant, together with the following, by the European 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. I am inclined to think that this species gradually passes 
into E. insularum; indeed, both were distributed by me as one species, and under n. 851. E. laxiflorum 
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. VERBENACEA. 
The most singular genera of Verbenacee occurring in tropical Polynesia are Faradaya and Overa (both 
represented by several species), and the monotypic Nesogenes (N. euphrasioides, DC.; Myoporum euphra- 
sioides, Hook. et Arn.). In the Hawaiian Islands we have three introduced species, viz. Verbena Bonarien-: 
sis, Linn., collected in Oahu (Seemann! n. 1719! Barclay !) ; Stachytarpheta dichotoma, Vahl. (Macrae !), 
and some Lantana, which, from the scrap collected by Lay and Collie, was referred, with a mark of doubt, 
to L. annua, Linn. Lippia nodiflora, Rich (Zapania nodiflora, 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.
