Elatostema filicoides, Seem. in Bonpl. vol. ix. p. 259.  Pellionia Vitiensis, A. Gray, mss. in Herb. 
Hook.— Woods on the banks of the Navua river, Viti Levu (Seemann! n. 421). Also collected by 
Williams ! and Harvey ! in Viti. 
An erect shrub, 4-5 feet high, much resembling some kinds of Fern in appearance. Stem terete, 
whitish ; branches and leaves distichous. Largest leaves 1-14 inch long, 3-4 lines broad. My specimens 
and those of Williams are sterile; those of Harvey, existing at Kew, have imperfect inflorescence, and are 
mere scraps. É

E. sessile, Forst. (Dorstenia pubescens, Forst. Prodr. n. 59. D. serrata, Sol. Prim. Fl. Ins. Pacif. 
(ined.) p. 320.  Procris sessilis, Hook. et Arn. Bot. Beech. p. 70), will probably be also met with in Viti, 
as it has been detected in the Samoan (Powell!) and Society Islands (Forster! Banks and Solander !), in 
. Lord Howe's Island (Milne! M‘Gillivray !), New Holland, Java, Philippine Islands, and Bootan. 
]. E. nemorosum, (n. sp.) Seem. (Tab. LXI.); hirsutum; caule erecto crasso suffruticoso ; 
folis alternis amplis obovatis acuminatis in petiolum alatum basi 1l-auriculatum attenuatis, ab ima 
basi usque ad acumen grosse et inzequaliter serratis, penninerviis, subtus in nervis hirsutissimis ; sti- 
pulis magnis lanceolatis persistentibus ; capitulis brevissime pedunculatis ; receptaculo inflorescentiz 
d discoideo.—Island of Taviuni (Seemann ! n. 422). 
One of the largest species of the genus, which must be placed amongst Weddell’s first ten species. 
Stem erect. Largest leaves from 12-15 inches long, and from 4-5 inches broad. Primary veins of blade 
12-15 on each side of the midrib. Male flower-heads not seen. Female flower-heads with a disk-like 
receptacle. Bracts long, linear, acute. F emale flowers pedicellate. Lobes of perigone linear.
