HAVARDII Rose, 1905

Distribution : Known only from the Big Bend region of western Texas and adjacent Mexico.

Desciption by Rose (1905) :

Closely resembling Sedum tuberculatum and S. retusum, but apparently not shrubby, low and much branched at base.

Stems covered with red tubercles.

Leaves flattened, 4 – 5 mm long, obtuse.

Flowers few, clustered near the tops of the branches, sessile or nearly so, calyx very small, about 1 mm long, petals narrow, 4 mm long, carpels widely speading.

Clausen adds (1981) :

Plants at higher altitudes have green leaves. These behave differently in cultivation and require a cold winter to induce flowering. Plants from lower altitudes, in the pinyon zone, have glaucous leaves that appear blue-green. Petals vary in the degree to which they are marked with pink.

Uhl writes (1985) :

Sedum havardii Rose has creeping stems with small spreading linear leaves and white to pale pinkish flowers.
