 VITIS LONGII, var. Microsperma (Munson). 



Plant: In native situations usually shmhhy, stocky, erect, much branched, similar to, but not 

 so profuse of branches, as V . rupestris, but more than V. vulpina; branches rapidly tapering, 

 angled slightly at first, soon terete; climbing when transplanted into low land and then more 

 vigorous than almost any other species; growing tips quite leafy, like V. vulpina, not so much 

 as V rupestris, foliage of a lighter, grayish-green cast, than V. vulpina, and easily distinguished 

 at some distance. 



Roots: Slender, branching much, very wiry and deeply penetrating; seedlings with -^ap 

 root, tapering downward, not transversely wrinkled. 



Wood: Tips whitish with cottony hairs which become fioccose and almost disappear the 

 first year, except about the nodes, where they remain mostly through the winter, young wood 

 soon finely striated, in maturity becoming a light grayish-brown. On old wood the bark is closely 

 persistent for several years, then becoming fibrous, not loose and thready, and sheds thin plates 

 as in V. vulpina; sectional view of annual wood much more dense, of a lighter green color, and 

 medullary rays more distinct " than in V. vulpina; nodes slightly, sometimes much, enlarged, 

 a Uttle bent; diaphragm plane thin, usually about twice as thick as in V vulpina; buds larger 

 and more woolly than in V. vulpina; tendrils generally once forked, rarely twice forked, short, 

 slender, and soon falling, unless they take hold early on some support, when they become very 

 much thickened and cling with great strength, at first are cottony, color red; internodes short, 1' 

 to 3', pith smaller and lighter colored than in V. vulpina, meeting the diaphragm abruptly. 



Leaves: Stipules 1/5' to 1/4' or more, long, membranaceous, becoming pale brown and 

 shedding when leaves are about half grown; petiole 1/2 to 3/4 the length of midrib, grooved 

 moderately on upper side, striated, both pubescent and cottony; color pale to dark red, usually 

 set at about right angle" with blade; blade 3}/2' to 4', rarely 6' wide, by 3' to 5' long, partially 

 folded together toward upper surface, similar to, but less than in V. rupestris, broadly cordate, 

 nearly round, rarely slightly three lobed or approaching reniform, usually less shouldered than 

 in V. vulpina, sometimes not at all; basal sinus generally broadly n shaped; basal lobes 

 spreading or approaching each other; sometimes lapping; teeth large, usually acute, convex, 

 mucronulate ; summit short taper-pointed. Venation of lower surface prominent, mostly 6 sometimes 

 7, nearly always opposite pairs of pubescent and sHghtly cottony ribs ; upper surface, when young, 

 appearing white, usually quite hairy, others little hairy, becoming appressed cottony or 

 fioccose when grown, and finally smooth and glossy, slightly rugose, dark green ; lower surface, aside 

 from ribs and nerves, smooth and much paler green, than upper surface; texture firm, leathery; . 

 leaves on ground shoots of old roots 3 to 5 lobed with lateral sinuses narrow and acute; entire 

 and not lobed on seedlings first year. 



Cluster: Fertile, — 2' to 3' long, simple, very compact, shouldered, peduncle very short, 

 making clusters appear nearly sessile, without false tendril rachis forked, the shoulder nearly 

 half as large as main cluster, woolly when young; pedicels short, thick, warty; staminate, 

 medium, simple, little if any larger than the fertile cluster. 



Flowers: Very fragrant; buds green; fertile, — stamens short, weak, reflexed and curved 

 laterally; pollen non- virile; staminate, — stamens long and strong; anthers large; pollen 

 abundant, and very efficient.
