Here is today's emblem and distich by Joachim Camerarius, 1:10. The peculiar phrase, fruit-losing, frugis-perda, is an imitation of Homer: ὠλεσίκαρπος, which Pliny reports in his own discussion of the willow in his Natural History.
Neglecta Iuventus
Perdere virtutum fructus cum flore iuventae:
Frugis perda salix ne vocitere cave.
Here is the vocabulary:
neglego - disregard, ignore
iuventus - youth
perdo - lose, destroy
virtus - virtue, excellence
fructus - fruit
cum - with, together with
flos - flower
iuventa - youth
frugis-perdus - fruit-losing
salix - willow
ne - no, not, so that not, don't
vocito - call
caveo - take care, be cautious
