This is an expository paper on connections between enumerative combinatorics and convex polytopes. It aims to give an essentially self-contained overview of five specific instances when enumerative combinatorics and convex polytopes arise jointly in problems whose initial formulation lies in only on

Simion, R., Trees with l-factors and oriented trees, Discrete Mathematics 88 (1991) 93-104. In this paper we present some results on trees with a l-factor: generating functions and asymptotics for the number of such trees, labeled, rooted, planted and unlabeled. We show that almost all trees with a
