Seed cones 1.5-2 cm across, the rim and outer face of the scales both strongly warty, the subapical point moderately developed. Seeds black, the body 5-10 mm long, conical, curved the larger wing to 3 mm wide, the smaller rudimentary.

Conservation Status

Red List Category & Criteria: Near Threatened

(Widdringtonia schwarzii has a restricted distribution in the Baviaanskloof Wilderness Area. There is some uncertainty about its area of occupancy although it is considerably less than 500 km2. The number of locations is between 5 and 12 depending on the method used to determine them. The species was heavily exploited in the past for its durable timber that was used for house construction, but most logging probably took place more than 120 years ago (i.e. more than three generations ago). Its habitat has also been modified by the increased frequency of fires as a result of human activities in the area and the expansion of agricultural activities. Fires continue to have an impact on this species. The extent of past decline is difficult to quantify due to a lack of information about the extent of its past distribution. The most recent Red List of South African Plants (Raimondo et al. 2009) assessed this species as Near Threatened on the basis that it almost met the D2 criterion  for Vulnerable. Given the discovery of additional localities in the Kouga Mountains, it seems unlikely that any single threat would impact the whole area to drive this species very quickly to Critically Endangered or extinction. In this assessment the Near Threatened category is maintained)
