DouBTFUL SPECIES 
CorRiISPERMUM PiLosuM Raf. New Fl. 4: 46. 1838. Described from specimens collected 
in Florida by Kin [or Kinn]. No species of the genus has been collected along the southern 
Atlantic coast in recent years. The plant may be C. hyssopifolium L., if it was correctly 
referred to this genus. 
VII. SALICORNIEAE. Succulent glabrous herbs or shrubs with articu- 
late branches. Leaves scale-like, opposite or alternate. Flowers mostly per- 
fect, usually in glomerules of 3 in the axils of bracts, often sunken in the stems; 
perianth-segments 3 or 4, united nearly to the apex, herbaceous or mem- 
branaceous. Stamens 1 or 2. Seed erect; embryo annular or conduplicate. 
Bracts subtending the flowers alternate, arranged spirally. 21. ALLENROLFEA. 
Bracts opposite. 
Bracts free, deciduous, subpeltate, the inflorescence strobiliform. 22, HETEROSTACHYS. 
Bracts united, persistent. the flowers sunken in depressions of the branches. 
Seed glabrous; endosperm present; embryo curved. 23. ARTHROCNEMUM. 
Seed pubescent; endosperm none; embryo conduplicate. 24. SALICORNIA. 
21. ALLENROLFEA Kuntze, Rev. Gen. 545. 1891. 
Spirostachys S, Wats. Proc. Am. Acad. 9: 125. 1874. Not Spivostachys Sonder, 1850. 
Much branched, glabrous, erect, succulent, suffruticose perennials with alternate branches, 
the branches articulate. Leaves reduced to short scales. Flowers perfect, sessile, arranged 
spirally by 3’s or 5’s in the axils of fleshy, peltate, persistent or tardily deciduous bracts, 
forming dense cylindric sessile spikes. Perianth obpyramidal, small, angled, truncate above, the 
apex truncate or 4- or 5-lobed, unchanged in fruit. Stamens 1 or 2; filaments exserted; anthers 
broadly oblong or orbicular. Stigmas 2 or rarely 3, short, usually distinct. Utricle ovoid, 
compressed, the pericarp membranaceous, free. Seed erect, oblong, smooth; embryo partly 
enclosing the copious endosperm; radicle inferior. 
Type species, Spirostachys occidentalis S. Wats.
