Proboscidea sabulosa
|
Proboscidea sabulosa is an annual, hairy- and sticky-leaved herb with rounded leaves. Plants are about 0.4 m across and high, with rounded dark green leaves that are very glandular and somewhat pungent. The creamy white, purple spotted flowers grow in clusters under leaves. The woody fruits are large and distinctive, forming two long curved horns at maturity. The large seeds, approximately 1 cm long, are corky. Native Americans used the fruits in basket-making, and pickled the young fruits.

Habitat

P. sabulosa grows in deep sands of semi-stabilized dunes in the desert scrub and arid grasslands of the Chihuahuan desert. Found at elevations of 900 to 1,400 meters (3,000 to 4,600 feet). (New Mexico Rare Plant Technical Council 1999) |
Distribution
| |
Found in five counties in New Mexico, adjacent Texas, and Mexico, in the Chihuahaun desert. (New Mexico Rare Plant Technical Council 1999) |

Ecological
Relationships
| |
As stated by the New Mexico Rare Plant Technical Council (1999):
• A widely scattered, regional endemic annual plant.
• Can become locally abundant during wet years.
• Dry fruits are dispersed by attaching to the feet of local animals.
• Not palatable to grazing wildlife or cattle. |

Current Research Summary
| |
Proboscidea is an interesting genus in cultivation. It is reputedly difficult to germinate from seed, and indeed, recent frozen storage tests at Desert Botanical Garden have had disappointing results. However, Proboscidea althaeafolia is being grown in a display garden on the ethnobotanical trail at the Garden with relatively little effort. Seeds are sown directly into the soil with no pre-treatment, and found to germinate readily. |
Current Management Summary
| |
There is no formal management plan. |
Research Management Needs
| |
Needs include population monitoring and understanding aspects of reproductive biology and ecology. |
