SALICORNIA 
Annual. Stem usually erect, rarely prostrate, up to about 20 — 25 cm. high, rigid. Branches 
numerous, arising at acute angles. Segments 
yellowish green, fading to a brownish yellow, 
about 5 — 8 mm. long. Spikes very short, ter- 
minal ones up to about 6 mm. long and about 
2 — 4 fertile segments, lateral ones up to about 
3 mm. long and usually with 1 — 2 fertile seg- 
ments ; sterile basal segment about 1 — 2 mm. 
long, tapering at the base ; spikes disarticulating 
as a whole shortly before the seeds are ripe. 
Flowers solitary, the lateral ones being totally 
suppressed, reaching about two-thirds of the way 
up the segment ; September. Stamens 1. Seeds 
ripe in late October and early November. 
The uniflorous character is remarkably constant. Many 
thousands of flowers have been examined, and only in 1 or 2 
cases has a cyme been observed with a second abortive 
lateral flower. 
Drier parts of salt-marshes ; Carmarthen, Dorset, Isle of Wight, Hampshire, Sussex, Kent, 
Essex, Norfolk. 
Northern France (several salt-marshes between St Malo and Erquy). 
iS. disarticulata x. gracillima Moss and Salisbury in Camb. Brit. FI. ii, 196. 
Habit of S. disarticulata. Segments small but usually larger than in S. disarticulata. Spikes 
small but larger than in S', disarticulata. Cymes with 1 — 3 flowers. 
Intermediates between S. disarticulata and other species of the genus are either very rare or, perhaps (if the 
uniflorous character disappears in hybrids), difficult to distinguish. However, there are specimens in the private her- 
barium of the Rev. E. F. Linton which approach S. disarticulata in habit, in the small size of the segments, and 
which have triflorous cymes and larger spikes than in S. disarticulata ; and similar plants were included in a gathering 
of 6 1 . disarticulata , which Mr C. E. Britton sent to the British Botanical Exchange Club in 1912. Mr Linton’s plants 
were collected in Dorset, Mr Britton’s in Essex. We refer them to the putative hybrid S. disarticulata x gracillima. 
Very rare. Dorset and Essex. Not known elsewhere.
