Vitis bourquiniana Munson
Family: Vitaceae
Description: A grape differing from the common V. arizonica Engelm.
by having leaves permanently tomentose beneath rather than glabrate. It is presently
treated as a horticultural variety of V. aestivalis
Michx. var. bourquiniana (Munson) Bailey.
Distribution: This variety is apparently a southern cultivar;
the species, V. aestivalis, is eastern North American (see
discussion in comments).
Plants Seen or Cited: NM, Bernalillo Co., Sandia Mts.,
La Cueva Canyon, found along a small stream with Virginia Creeper,
8400', 10 Aug 1965, C.B. Jones 200-1 (UNM). I did not
confirm the identification of this specimen, nor did I make a
note if M.O. Moore had seen it during the preparation of the
Vitaceae treatment for Flora North America.
Habitat: If. V. aestivalis var. bourquiniana:
Small stream with virginia creeper, 8400' (C.B. Jones 200-1,
UNM). If V. × doaniana: Sandy or alkaline soil, often along
streams, 5,000-6,000' (Martin and Hutchins 1980); Well-drained
soils of the Rolling Plains and Cross Timbers, 250-400 m (Moore
1991, unpubl.).
Comments: This name applies to a cultivated grape in the
South (Gray Herbarium Index, vol. 10, 1968), where it is listed
as a synonym of V. aestivalis var. bourquiniana.
This name does not appear in NM literature (Martin and Hutchins,
1980; Roalson and Allred 1996). Of particular note, it does not
appear in the work of a well-known splitter, J. K. Small (1903).
The name also does not appear in Moore (unpubl.). Rehder (1940)
distinguishes the variety within V. aestivalis, noting
that the pubescence on the abaxial side of the leaves is grayer,
less rusty, than the typical variety. Moore (unpubl.) maps the
three varieties that he recognizes within V. aestivalis
as being eastern North American, coming as far west as eastern
Texas and central North Dakota, but in his 1991 paper he does
not list V. bourquiniana anywhere.
The source of the record for New Mexico seems to be based upon
a single specimen at the University of New Mexico which may be
misidentified; this record has been picked up in the NMNHP data-base
as element PDVIT04050. The collector called it the "Doan
grape" on the label of the UNM specimen. Martin and Hutchins
(1980) treat the Doan Grape as V. doaniana Munson, mapping
it in Bernalillo and Socorro counties. Moore (1991, unpubl.)
recognizes this as a hybrid (V. × doaniana Munson
ex Viala), the parents being V. mustangensis Buckley and
V. acerifolia Raf. Moore notes the hybrid to be reported
from Colorado and New Mexico, but he saw no specimens from these
states. He maps the Doan Grape only from north-central Texas
and adjacent Oklahoma (unpubl.). When interpreted as a hybrid,
it is unlikely that the Doan Grape occurs in New Mexico; V.
mustangensis is restricted to eastern Texas and states adjacent,
and is not sympatric with V. acerifolia in its range in
New Mexico.
Status: Not rare. Apparently a southern cultivar of V.
aestivalis if V. bourquiniana. Presence in the state
needs to be confirmed by study of specimen cited above. Vitis
aestivalis, sensu lato, is a common species in the eastern
portion of North America. Whether considered V. bourquiniana
or Doan's Grape, it is most likely New Mexico records are based
on misidentifications or on range extensions of peripheral and
not rare species and/or hybrids.
