A Grammatical Dictionary of Botanical Latin

Julus,-i (s.m.II), abl.sg. julo: catkin; modern Latin for an amentum or spike, an old term for catkin, or spike, such as in Acorus Calamus L. (Jackson 1928); [> L. iulus (-os),-i (s.m.II), a catkin = Gk. ioulos, = oulos, “the young hair at the side of the face, the whiskers” and oulos,-E,-on (Gk. adj.) woolly, woolen; (of plants) twisted, curling, crooked” (Liddell & Scott)]; see catkin, ament;

NOTE: Dillenius uses ‘julus’ in the sense of ‘spike’ (not ament): - Lycopodium elatius abietiforme, julo singulari apode (Dill.), the taller fir-tree-shaped Lycopodium, with a single, stalkless spike.

- Lycopodioides denticulatum pulchrum repens, spicis apodibus [“The creeping dented Lycopodioides, with footless Spikes]” (Dill.), with the spikes [i.e. juli] lacking stalks [i.e. 'feet'].
