In botany class, we became quite good at identyfying types of flowers. IS identyfying PP DO
I think the OP means to ask if "identifying" is a past participle or direct object. But I could be wrong...
The word is spelled "identifying" and it's a gerund serving as the object of the preposition "at" -- and "types" is the direct object of "identifying" and "of flowers" is a prepositional phrase modifying "types."
