f to 4in. long, slightly dilated at the top. Spikes terminal, oblong-cylindrical, 
rounded at both ends, very compact, 4 to fin. long, 2 to 24 lines diameter, the 
articles very numerous, closely imbricate, the margins dilated into opposite 
semicircular scarious scales, without projecting points, but forming projecting 
acute lines. Flowers in threes, all apparently hermaphrodite and monandrous. 
Perianths immersed in and adnate to the rhachis at the base, thin and free at
