Yibvirnum rufidulixm Raf,, var. Palmeri var, nov. 
Viburnum rufidulum Haf«. var. Palmeri var. nov. A small tree, mostly 
4-6 m, tall; leaves elliptical-ovate, mostly rounded and obtuse at apex, rounded 
to cuneate at the base, at maturity coriaceous, dark-green, and very lustrous 
above, pale and dull below, blades asually 5 cm. long or less and 3.5 cm. broad 
or less (the largest leaf noted was 7.5 cm, long and 4 cm. broad and acutish,) 
finely serrate, with pale, stout midrib, markedly prcaninent below and with 5 or 
more primary veins on each side of midrib and numerous reticulate veinlets, in 
early growth covered below with thick, ferpugineous toraentum, becoming essentially 
glabrate in age; petioles stout, grooved, up to 10 mm. long, but mostly about half 
that length, narrowly wing-margined; inflorescence borne in short-stalked, compound, 
usually 4-rayed, glabrate corymbs; fruit ripening in August, oblong, bright-blue, 
covered with a glaucous bloom, 10-12 mm. long and 8-9 mm. broad; stone flattened, 
not grooved, oblong, about 10 mm, long and 8,5 mm, broad. 
This variety is somewhat intermediate between V. rufidulum and V. prunifolium , 
but its essential affinity is with the former species. This variety is named for 
Mr. Ernest J. Palmer, of the Arnold Arboret'om, who in correspondence called to my 
attention the circiamstance that on one of his field trips in '-^'exas he had collected 
at Spanish Pass a Viburnum that appeared to be different from the known species. 
In response to this information a trip was made to Spanish Pass in late ^Jarch to 
collect this Vibuminn in flower and another trip was made late in August to collect 
it in fruit. The type specimen, No. 19380, was collected August 26, 1936, at which 
time the Viburnum was in mature fruit, on a hill on the west side of the railway 
and about 13/4 miles north of the summit of Spanish Pass as indicated by the rail¬ 
way that uses this pass in traversing the hills. This variety differs from the 
..^jspecies in being a smaller tree, in ripening its fruit a month or so earlier, in 
having foliage much smaller and becoming essentially glabrate fairly early in the 
season, and in having smaller fruits and, consequentially, smaller stones.
