Description

A low, small, spreading, many-branched tree. It produces many stilt-like roots, along the trunk, but also along the length of the side branches. It can be distinguished by its compact (often trifarious) rosettes of small, rigid, erect, red-spined, deep blue-green leaves. These are usually only 75 cm long and 6 cm wide, folded lengthwise (reduplicate), stiff, erect, and have an abrupt, obtuse leaf tip. The reddish spines are closely set along the margins of the leaves. The small (7–8 cm) fruit head is held erect on a short peduncle, and it is enclosed in three-ranked (trifarious)
