204 DIOECIA— DIANDRIA. Salix. 



Tab. 1058 of the Fl. Dan. named 5. lappoman, answers in many 

 particulars to this species, though I know no Willow whose s/y;e.v, 

 or stigmas, exactly resemble that figure. The true lapponitm is 

 represented in t. 197 of that work^ for arenaria, as already men- 

 tioned. 



39. ^. a?-enaria. Downy Mountain Willow. 



Leaves nearly entire, ovate, acute ; reticulated ami some- 

 what downy above : veiny and densely woolly beneath. 

 Style as long as the sessile woolly germen. Stigmas 

 linear, deeply divided, the length of the style.

Shrub. 31 ay, June. 



A'larger and stouter s/irwi than the last, of which it was supposed, 

 'by the original finder, to be the fertile plant ; but barren as well 

 as fertile individuals of both species, agreeing exactly together 

 in other respects, and dilfering alike from correlative ones of 

 the other species, arc now well known. In size and general 

 habit, this most resembles S. glauca, but their discriminative 

 marks arc clearly discernible. The leaves of arenaria are rather 

 smaller and shorter, more precisely ovate, with a little sharp 

 point J their upper surface dark green, reticulated with sunk 

 veins, and clothed witli thin cottony down, more dense and soft 

 upon the young ones ; the under side pure white, witli close, 

 dense cottony wool ; the veins prominent; midrib reddish ; the 

 youngest, as well iis,/loral ones, beautifully silky beneath. Sli- 

 pulas none. Footstalks broad at the base, not dccurrent, though 

 with some swelling of tlie branch below their insertion. Catkins 

 on short lateral branches, with nfi;w/loral-leaves; barren ones 

 ovate, short and thick ; fertile longer, cylindrical. Scales of 

 each ovate, more or less acute, blackish, co])ious!y bearded. 

 Nect. oblong, obtuse. Stam. twice the length of the scale. 

 Germ, sessile, ovate, acute,, covered with thick white wool.
