What's the difference between reniform and retiform?
Reniform
Definition:
(a.) Having the form or shape of a kidney; as, a reniform mineral; a reniform leaf.
Example Sentences:

Retiform
Definition:
(a.) Composed of crossing lines and interstices; reticular; netlike; as, the retiform coat of the eye.
Example Sentences:
(1) A review of 15 well-documented cases of proliferative periostitis reported in the literature and a description of six new cases, five fully documented, have shown the following: a variety of irritants both odontogenic and nondontogenic in origin may induce neoperiostosis in the mandible; radiographically, cortical redundancy and preservation of the original cortical outline are the most common findings; and microsocopically, a fibro-osseous pattern evincing one of the three trabecular orientations--parallel, retiform, or haphazard fibrous dysplasia-like--is featured.
