General: Woolly Plantain (Plantago patagonica) is a small annual forb that has 2-4(8) inch long, linear leaves that all grow from the base. The inflorescence is a short stem with a single, cylindrical mass of bracts harboring tiny whitish, 4-part flowers. The leaves and flowering stalks are covered with long hairs. On the flower stalk (peduncle), the hairs are stout and all angle up. On the leaves, the hairs are longer and go in all directions. A long bract sticks out from below each flower.
A similar species, Desert Indianwheat, looks similar to Woolly Plantain, but Desert Indianwheat has hairs on the peduncle that go in all directions, and its bracts do not stick out from below each flower.
Woolly Plantain an uncommon component of vegetation communities in dry, well-drained sandy and gravelly soils on desert flats and bajadas into the lower mountains from the Lower Sonoran (Creosote-Bursage Flats) life zone to the Upper Sonoran (Pinyon-Juniper Woodland) life zone.
Around Las Vegas, look for Woolly Plantain everywhere in desert habitat, but look closely because it is hard to tell from the abundant Desert Indianwheat, with which it looks identical at a glance.

For such a small plant, it produces relatively large seeds and provides an important food source for desert tortoise, desert iguana, and other vegetarian creatures. |
