Ipomopsis
tenuituba. Synonyms:
Gilia tenuituba, Gilia aggregata, Ipomopsis aggregata variety macrosiphon. Polemoniaceae (Phlox Family) Montane, sub-alpine. Woodlands, meadows, openings.
Summer, fall. I. tenuituba is very similar to I. aggregata and I was not aware of the differences until a number of years ago I received a very helpful email from Dieter Wilken of the Santa Barbara Botanic Garden. Dieter indicates that the two plants differ in several key ways. The following comparison is mostly in Dieter's words:
I.
tenuituba tends to occur at relatively high elevations or at least in
subalpine fir and higher elevation sagebrush communities.
I.
aggregata has a wide range of ecological associations but generally
is not at the upper limits of subalpine forest.
I. tenuituba
has a pale pink to lavender, sometimes very light purple corolla. I. tenuituba has
a more slender tube and is about 20-45 mm long. I. tenuituba has
long, slender calyx lobes. I. tenuituba has
anthers within the tube, with no more than one anther
protruding from the throat.
I.
tenuituba generally produces nectar in the early morning or late
afternoon, is sweet-smelling in the evening, and is pollinated
principally by moths, sometimes butterflies.
I.
aggregata generally produces nectar during the day in large
quantities, is odorless, and is pollinated principally by
hummingbirds.
The
two species do hybridize.
This species was first collected by Edward Palmer (1831-1911) in Utah in 1877 and was named Gilia tenuituba by Per Axel Rydberg in 1913. It was renamed Ipomopsis tenuituba in 1956 by Gilia experts Verne and Alva Grant. "Tenuituba" is Latin for "thin/slender/stretched tube". |
