Betty and I discovered the Ipomopsis species shown on this page in 2006 and John Bregar and I described the species and published it September 14, 2011.   Click to read the new species description.

    Betty and I discovered the plant in a side canyon of the Dolores River, about 40 miles northeast of our home.  We had driven the scenic road along the canyon wall many times on our way to hiking the Colorado Trail, but we had never noticed the Ipomopsis until it caught the corner of my eye in June of 2006.  We quickly got out of our car and were delighted to find such a beautiful plant.  When we could not identify the plant using any botanical keys, we sent specimens to several prominent botanists.  They indicated that the plant was just a form of an already known species. 

     Over the next years, Betty and I observed the plant many times, surveyed the extent of its population along the road, and wondered again and again if it really was an already described species.  This year I decided to settle the question and I did a very thorough analysis of the minute characteristics of the plant.  When I compared the results with details of known Ipomopsis species, it was clear to me that we had a new species.

     I shared my findings with professional botanist, Guy Nesom, my good botanical buddy, John Bregar, and others, and we all concluded that we should proceed with the description and publish the new species.  We sent the description to the top two experts in Polemoniaceae (Phlox, the family to which Ipomopsis belongs) and they agreed that we had a new species.

    We named the new species "Ipomopsis ramosa" for its distinctive, many-branched form ("ramosa" in Latin). 

     Five years may seem a long time between finding and publishing a new species, but in botany, that is about par.  It is actually not uncommon for new descriptions to lag decades behind their discovery.  Occasionally descriptions can come with the speed of light:  Three years ago Peggy Lyon and I discovered Gutierrezia elegans and had it published as a new species just three months later.  That was a remarkably short time.   Betty and I discovered our second species, Packera mancosana, in 2008 and published it in June of 2011. 

    More about the genus Ipomopsis: The Ipomopsis genus was named by Andre Michaux in 1803;  20th century Gilia experts, Verne and Alva Grant, re-assigned many plants in the genus Gilia to the Ipomopsis genus in 1956.

    The Ipomopsis genus is characterized by plants with leaves that are entire to deeply pinnately lobed; flowers that are, salverform, white to purplish, red, or pink, terminal, paniculate, pedicelled, actinomorphic, and subtended by a single bract; stamens that are unequally inserted on the corolla tube or throat; filaments that are equal or unequal in length; anthers that are included to exserted; and a style that is included to exserted. (Adapted from Wilkens and Porter, Canotia, 29 Nov 2005-vol 1).  

     "Ipomopsis" means "similar to Ipomoea" ("Morning Glories", one of which has a tubular red flower which must have reminded Michaux of an Ipomopsis flower).

This is a beautiful new species of Ipomopsis found in just two side canyons of the upper Dolores River in southwest Colorado.  In these two canyons it is abundant from about 8,200-9,300 feet in elevation.

Ipomopsis ramosa shares many characteristics of the Ipomopsis genus, but there are a number of striking characteristics that set it apart from other Ipomopsis species:

the floral tubes are quite short, only 15 millimeters;

the style is only 2-4 millimeters;

the plants branch frequently from the base and along the main stem producing a bushy growth pattern;

and the flower color is white and coral-pink. 

Basal rosettes are withered at flowering, plants are densely covered in glandular hairs and sparse silky hairs, leaves are light green, and plants are 12-18 inches tall.  Plant height, flower dimensions, flower color, etc. are quite uniform from plant to plant although there are a few plants with very light-colored corollas and even some albinos.

Leaves are deeply divided and stems are often multiple and many-branched.

The five anthers and one style are buried deep in the floral tube. The five varying length filaments and the anthers  extend about half way up the floral tube and the style is only 3-4 millimeters so none of the sexual parts are visible in this photograph.

Notice the hairiness on the outside of the floral tube as well as on the multi-colored calyx.  The flora tube is heavily streaked coral-pink, the inside of the lobes is lightly dotted coral-pink, and the back of the lobes is streaked coral-pink.  Flower lobes are reflexed.

Although the flowers are actually coral-pink, they often appear to be orange or salmon  --  even when you see them in person.

The floral tube is just 14-17 millimeters long and about  1 millimeter wide at the base in the calyx and 2 mm at the orifice just at the base of the lobes.

A comparison of the floral tube, calyx shape, color, hairiness, etc. of the new species of Ipomopsis with other Ipomopsis species shows significant differences.

Notice that in the middle of the tube, you can see two slightly separated darker areas.  The tube is so translucent that you are looking at the anther sacs inside the tube.  These sacs give the tube an orange tint.

On the right side of the photograph, the corolla has fallen from the calyx and the green seed-bearing capsule and bent-over straw-colored style now show.  The capsule will swell 1-2 millimeters more (it is about 3 millimeters in this photograph) and then it will dry and split, spilling its seeds.

Notice the hairiness of the entire plant.  The short glandular hairs give the plant a very spicy fragrance.
