Lycopodium clavatum (?)
Growing along a partly sunny trail at Mt. Kenya Forest Preserve, Kirinyaga, Kenya. 01 June 2017.
Feathery mostly herbaceous fern-like plant up to a meter tall. The vegetative branching is dichotomous, i.e., splitting into two at each branching point. The short leaves along the branches suggest another common name, 'ground pine'. The plants tend to grow in moist soil where shade predominates for much of the day. There are no flowers and reproduction is mostly asexual by spores or by creeping rhizomes. The spores are borne in sporangia on upright catkin-like spikes.
