The new species Pelargonium uliginosum is a local endemic of Breede River Alluvial Fynbos in the upper Breede River Valley, Western Cape, South Africa. One of the eight species of sect. Hoarea with only the posterior two petals developed, it is distinguished by its glabrous, bi- or tripinnatisect leaves with subulate ultimate segments each tipped with one or sometimes two setae.
