	abstract = {In this paper we present a rigid-rod model (involving a restricted set of orientations) which is solved first with mean-field theory and then by Monte Carlo simulation. It is shown that both interparticle attractions and anisotropic adsorption energies are necessary in order for two successive fluid-fluid transitions to occur. The first is basically a gas-liquid condensation of {\textquoteleft}{\textquoteleft}lying down{\textquoteright}{\textquoteright} rods in the plane of the surface, and the second involves a {\textquoteleft}{\textquoteleft}standing up{\textquoteright}{\textquoteright} of the particles. A close qualitative correspondence is established between the results obtained in the mean-field and Monte Carlo descriptions. The role of biaxial states, i.e., in-plane orientational ordering, is also discussed in both contexts. To this end, we develop an analogy between our one-component rod monolayer and a bidisperse system of interconverting isotropic particles.},
