. A tribe of Chenopodiaceae, popularly called ‘‘samphire’’ 
in Australia; low shrubs composed of imbricate articles more 
articles, but in Salicornia australis 1 or 2 pairs of flowers are 
added at each side of the triad, so that we have a row of 5 or 7 
flowers, instead of 3, or a whorl of 10 or 14 flowers, instead 
of one of 6. In Tecticornia cinerea, on the other hand, the 
triad is doubled and there are 6 flowers under each scale, or a 
whorl of 12 in all. The flowers are more or less protected by 
the margin of the article just below them. The article is 
usually regarded as consisting of 2 opposite rudimentary 
leaves, united by a sheath and combined with a succulent base 
which surrounds the whole internode. 
n all the genera except Tecticornia the articles are 
practically of one form and there is so little difference between 
barren and fertile articles that in Arthrocnemum halocnem- 
odes and Pachycornia tenuis one sometimes finds new shoots 
springing from the summit of the flowering spike, or the 
lower articles of the spike are barren. In Tecticornia the 
barren articles resemble those of other genera, but the fertile 
ones are split to the axis into 2 spreading opposite scales, and 
the stout Spike consists of these scales decussately arranged 
along the axis. 
The flowers are either bisexual or male only. In most 
* Species they are bisexual, but in Arthrocnemum 
arbuscula and in Pachycornia the central flower is bisexu 
and the 2 lateral ar e. is usually one stamen to 
s . The stamens ripen and protrude while the pistil is 
still very young, and this fact may easily lead to error in the 
examination of relaxed specimens, because the stamen is con- 
| eem. while the pistil is very difficult to find, and a flower
