A very peculiar plant, of which there are two forms, the one from the highest 
altitudes being much condensed with smaller stiffer leaves, and much more thorny, the 
stem, midrib and petioles of the leaves and rachis of the inflorescence being densely, 
armed with hooked thorns. The petals are for half their width or more covered with 
a woolly pubescence like the sepals, and apparently fall off shortly after the flower 
opens. The sepals then spread open in a star-like fashion. The stamens and pistils 
are comparatively few, the latter very small, and surrounded at the base by hairs.
