Here are some notes on sources for Byzantine Science; in this case botany.
Botany was not a subject of real interest to the Byzantines. The Byzantine interest in plants was entirely practical. As such they compiled lists of plants useful for medicine – materia medica -, or for magical use. They are also noted for the copying of ancient botanical texts such as Dioscurides, with its copious illustrations of plants and their properties. (An example appears at the foot of this post).

Botanical lexicons / glosses. The lexicon or glossary became the usual form of botanical knowledge transfer in late antiquity and Byzantium. These were usually only alphabetic to the extent of the first letter. The botanical glossaries preserved in Byzantine manuscripts often give the impression of private notes, made more or less ad hoc on blank pages of manuscripts. They are usually short, and anonymous, except for those of ps.Galen, Nikomedes, and Neophytos Prodromenos. The manuscripts are usually 15-16th century. It is rare that these texts can be assigned a date, or read without difficulty because of the careless handwriting, and the use of terms from Latin or Arabic.
Editions: A. Delatte, Anecdota Atheniensia 2, (1939), 273-454, includes 15 botanical glossaries, including ps.Galen, ps.Symeon Seth, Neophytos, Nikomedes, Nicholas Hieropais. (Review here) M. H.

Neophytos Prodromenos. A 14th century monk and scribe of Albanian origin in the circle of Manuel II Paleologus. He wrote a compendium of Aristotelean logic, also on the 24 letters of the alphabet and on Indian numbers, as well as theological works, and works on medicine. He compiled a lexicon / botanical glossary probably for the needs of the hospital founded by the Serbian king Uros II Milutin in the monastery of Petra in Constantinople. He also did research on cancer and oral and teeth diseases, and proposed strengthening by binding the teeth with woolen thread.
