On the other hand, as the fertility of this clover absolutely depends on bees visiting the flowers, if humble-bees were to become rare in any country, it might be a great advantage to the plant to have a shorter or more deeply divided corolla, so that the hive-bees should be enabled to suck its flowers.
Beste alde batetik, hirusta mota honen ernalmena erleen bisitaren mende erabat dagoenez gero, baldin eskualde batean erlastarrak urrituko balira, landarearentzat abantaila handia izan liteke korola laburragoa edo sakonkiago banatua edukitzea, erle arruntak haren loreak xurgatu ahal izanen lituzke eta.
