L. recurvata is a characteristic species with no very closely 
related forms. Normally it is an extremely slender plant with 
nearly filiform stems and pedicels. On technical characters it 
may be confused with L. aurea, but because of the latter’s coarse 
habit of growth the two are of quite different appearance. Their 
ranges are widely separated. L. recurvata comes from a region 
where the soils are predominantly rich in lime, and some of the 
specimens examined were labeled to the effect that they grew 
upon caleareous soil. Its range lies within the lower austral 
life zone of Merriam.
