BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Oxytropis podocarpa | Stalked-Pod Crazyweed
GENERAL BOTANICAL CHARACTERISTICS :
Stalked-pod crazyweed is a low, caespitose, native perennial autotrophic
forb, which forms small, dense cushions. The pinnately compound basal
leaves are 1 to 2 inches (2-5 cm) long. The erect or prostrate stems
are up to 3 inches (7 cm) long. The racemes have one or two purplish
flowers. The pod has a 2 to 5 mm stipe, and the body is inflated,
papery, and up to 1 inch (25 mm) long. [5,9,11].
RAUNKIAER LIFE FORM :
Hemicryptophyte
REGENERATION PROCESSES :
Crazyweed reproduces sexually by pollination and fertilization and
propagates by seed [2].
SITE CHARACTERISTICS :
Stalked-pod crazyweed grows on exposed, rocky, alpine ridges or turfy,
alpine hillsides, often on limestone substrates [5,9]. It has been
reported at 7,300 to 8,200 feet (2,225-2,500 m) in Montana [11] and at
12,500 feet (4,030 m) in Colorado [4].
SUCCESSIONAL STATUS :
NO-ENTRY
SEASONAL DEVELOPMENT :
Stalked-pod crazyweed flowers in June and produces fruit from late June
to August [11].
