Selaginella gigantea

A remarkable spikemoss from Venezuela's coastal mountains. It is the only Selaginella that grows as a true shrub, up to about 2 m tall, with very small leaves. It is known only from wet evergreen forest on steep slopes above the Río San Gián near Borburata in Carabobo, at 600–750 m. It needs warm, shaded, very humid conditions and a lot of space, so a large greenhouse or tall enclosure suits it better than a small terrarium.

Where it grows wild

Steep, forested slopes beside a stream running into the Río Borburata (Río San Gián), in wet, primary, evergreen forest. It grows as an upright shrub in the forest understory near the watercourse. Leaves are no more than about 5 mm long, and strobili are up to 2 cm long.

Specimen labels give 600–750 m, and most measured records are at 725 m.
