Lessingia glandulifera varieties

Geographic Distribution


This page is just a placeholder for now for the geographic maps of the two varieties.

Geographic Distribution

Lessingia glandulifera var. glandulifera is a very wide-spread taxon, whereas Lessingia glandulifera var. tomentosa, the Warner Springs lessingia, is known to exist only in a very small area in the vicinity of Warner Springs, east of Lake Henshaw.

It just barely enters ABDSP at its western boundary, from a single plant that was almost surely a waif, brought in by firefighters from the Warner Springs area when they were fighting the August 2012 fire here. The single plant was observed in the next year, on 27 October 2013, all by itself, without any other Lessingia glandulifera plants nearby. There were a number of var. glandulifera plants within a mile of this waif.

Fig. 1 shows the distribution of both varieties in the Warner Springs area separately, on a relief base map. Fig. 2 shows the distribution map of both species together, without a relief base map.

Fig. 1. Geographic distribution maps, from our data and from vouchers with good locations, in the Lake Henshaw / Ranchita area. Left: var. glandulifera. Right: var. tomentosa. The single point near Ranchita is almost surely a waif, brought in by firefighters in August 2012.

Fig. 2. Geographic distribution maps for both varieties as indicated, from our data and from vouchers with good locations, in the Lake Henshaw / Ranchita area. Larger symbols for var. tomentosa are used, to show its geographic range more prominently, and to prevent the symbols from being hidden by symbols for var. glandulifera plotting at the same location. Note that there are only two small areas where only var. tomentosa is found, with it co-occurring with var. glandulifera at the edges of its range. See Fig. 1 for geographic reference points.
