There is (or at least was) an organization called IPGRI. They have published many booklets that they call "Descriptors". They describe in great details every part of the plants. It is in English with pen drawings. There is one on Citrus. For Citrus relatives within the Rutaceae family it is a little more difficult. They may have published new booklets since the last time I looked. A quick Google search for IPGRI Descriptors for xxxx will tell you if they have what you seek.
