Description from http://www.swcoloradowildflowers.com
"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. aggregata has a red to orange-red corolla.

I. tenuituba has a more slender tube and is about 20-45 mm long.
I. aggregata has a tube about 15-25 mm long.

I. tenuituba has long, slender calyx lobes.
I. aggregata has shorter, tapering calyx lobes.

I. tenuituba has anthers within the tube, with no more than one anther protruding from the throat. 
I. aggregata has 3-5 anthers in the throat or protruding beyond 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." Al Schneider  who received the information from Dieter Wilken of the Santa Barbara Botanic Garden
