Exsiccata : — Billot, 2525, as Obione pedunculata ; Fries, i, 57, as Halymus peduncidatus ; Reichenbach, 483, 
as Halimus pedunculatns ; Wirtgen, viii, 398, as Halimus peduncidatus. 
Annual ; very mealy and silvery-glaucous. Stem erect, from about 3 — 30 cm. high, usually 
5 — 20, slender, rather zigzag, angular, subsimple or branched, branches 
spreading or decumbent. Leaves alternate. Petioles short. Laminae ovate- 
lanceolate to obovate-lanceolate, entire, apex rounded and often with rather 
blunt apiculus, rather succulent, about i'2 — 37 cm. long. Partial inflorescences 
lax, interrupted, axillary. Flowers in August and September. Pistillate flowers 
subsessile, pedicel elongating greatly as the fruit ripens. Fruiting bracteoles 
obdeltoid, compressed, united almost up to the top, 3-lobed, the central lobe very 
small, the lateral lobes spreading. Mature pedicel up to about 1 2 — 13 mm. long. 
Seeds small, nearly 2 mm. in diameter, compressed, dull, light brown. 
The A. maritima nostras ocimi minoris folio Ray loc. cit. was probably a dwarf-form of 
this species: it was named A. pedunculata var. humilis by Gray in his Nat. Arr. ii, 282 
(1821). 
An extremely large form, with laminae 2 — 5 cm. long and very thick, was collected 
among rubbish on a salt-marsh in Kent in 1902 by Mr H. Groves. 
Very rare ; on salt-marshes, in the wetter portions of the associa- 
tion of Glyceria maritima. Kent, Suffolk, Norfolk, Cambridgeshire and 
Lincolnshire : only found recently, we believe, in Kent : an Irish record from 
western Galway is perhaps due to some error. Rarely adventitious on foreign 
ballast, as in Durham and Carnarvonshire. 
Western Europe, from southern Sweden to Normandy, Baltic coasts — Germany and north- 
wards to Osel in Russia, central Germany, south-eastern Europe ; Asia Minor, Caucasus, central 
Asia.
