semierect

adj

1. (not-comparable)Partially or somewhat erect.

   “It is a singular and very interesting sight to watch a Mias making his way leisurely through the forest. He walks deliberately along some of the larger branches in the semi-erect attitude which the great length of his arms and the shortness of his legs cause him naturally to assume; and the disproportion between these limbs is increased by his walking on his knuckles, not on the palm of the hand, as we should do.”

   “Elytra a little longer than wide conjointly, finely striate, intervals with a row of moderately coarse elongate punctures each bearing a semierect hair, surface subgranularly alutaceous.”

2. (not-comparable)Partially or somewhat erect.
3. (not-comparable)Having a partially or somewhat erect penis.
