One to two feet long. Root thick, in some degree globular, from whence 
two or three principal stems proceed, which throw out branches on each 
side in an alternate series, two or sometimes more growing from the 
same knot or joint; and these also are subdivided into long slender 
thread-shaped but flattened leaves, each of which, as well as the second 
branches, are armed with short sharp-pointed prickles. Stems thread¬ 
shaped. Plant olive green. Major Velley. Stem crooked, twisted, wiry, 
the size of a small quill, solid, shining, smooth. Branches set with soft 
prickles pointing upwards. Fructifications in the forks of the lower 
branches, wart-like, irregular, granulated, yellowish, studded with 
brown. Stackhouse. Ner. Brit. p. 25. We are indebted to this gen¬ 
tleman for the discovery of the fructification, which he found in 
winter, and he suspects that many other species are to be observed in 
fruit during the winter months only.
