Ipomopsis congesta ssp. frutescens (Rydb.) Day
Family: Polemoniaceae
Synonyms: Gilia congesta Hook.; Gilia frutescens
Rydb.; Ipomopsis frutescens (Rydb.) V. Grant
Distribution: For the species as a whole: Oregon
to western North Dakota and south from southern California to
Colorado and western Nebraska (Cronquist et al. 1984); var.
frutescens: central Utah and adjacent Arizona and Colorado
(Cronquist et al. 1984); Arizona, Colorado, Utah (Garfield, Kane,
San Juan, and Washington counties) (Welsh et al 1993); var.
crebrifolia: southwestern Montana and western Wyoming
south to New Mexico (San Juan and Sandoval counties), Utah (Beaver,
Millard, San Juan, and Summit counties) (Cronquist et al. 1984);
Montana and Wyoming south to Utah (Beaver, Millard, Rich, San
Juan, Sevier, and Summit counties) and New Mexico (Welsh et al.
1993).
Habitat: For the species as a whole: dry, open places,
from the plains and foothills to high altitude in the mountains
(Cronquist et al. 1984); var. frutescens: [in Utah]
wide variety of habitats from sandy desertscrub through ponderosa
pine communities, 1155-2290 m (3800-7500 ft) (Welsh et al. 1993);
var. crebrifolia: [in Utah] wide range of habitats
from sagebrush through bristlecone pine communities, 1830-2780
m (6000-9100 ft) (Welsh et al 1993).
Plants Seen or Cited: Apparently
no records in the New Mexico Natural Heritage Program Database.
All specimens of I. congesta at UNM from New Mexico are
var. crebrifolia.
1. H. Hastings. Sn. 25 May 1940. San Juan county, NM. Hill southeast
from grade school, Aztec.
2. Fletcher. No. 5979. 11 May 1982. San Juan county, NM. Northeast
of Farmington with some gypsum.
3. Knight. No. 2173. 24 Jun 1982. San Juan county, NM. Los Pinos
River valley, just south of Colorado border in pinyon-juniper.
4. Spellenberg. No. 7789. 4 June 1984. Sandoval county, NM. 22
miles northwest of San Ysidro on NM-44 at mile post 46, south-facing
powdery clay roadbank, [forming] dominant vegetation, 100s of
plants, seen only here, with Juniperus monosperma. Corolla
cream.
Discussion: The species on the whole is common and widespread
within its range. "Gilia congesta is divisible, with
some difficulty, into seven ecogeographically significant but
wholly confluent varieties " (Cronquist et al. 1984). Welsh
et al (1993) say that "four rather clearly definable but
partially confluent varieties are present in Utah." Both
Cronquist et al. (1984) and Welsh et al. (1993) agree that var.
frutescens does not occur in New Mexico and that var. crebrifolia
is present in this state (see above). The former is present in
San Juan County, Utah, but most likely in the western part nearer
Kane and Garfield counties. The latter is represented at UNM by
the specimens cited above. Whether var. frutescens grows
in New Mexico or not, neither Welsh et al. (1993) nor Cronquist
et al. (1984) suggest that it is rare.
Recommendation: Place on L4 (Probably not present in New
Mexico and apparently common in its range elsewhere).
