ab hac ferula differt quae vocatur spondylion foliis tantum, quia sunt minora et platani divisura. non nisi in opacis gignitur. semen eodem nomine sills speciem habet, medicinae tantum utile.

CHAP. 58.—SPONDYLIUM. The difference between this kind of giant-fennel and that known as spondylium, consists only in the leaf, which is smaller, and divided like that of the plane tree. It grows in shady places only. The seed bears the same name as the plant, and has a strong resemblance to that of hart-wort: it is only employed in medicine.
