http://www.texasstaghornferns.com/images/Elemaria/photo%2011.JPGThe P. elemaria is a fairly new hybrid species combining spore from P. andinum and P. elephantotis.  Originally  though to be part P. stemaria but recent DNA tests show P. andinum the parent.  The fertile fronds are dark green with a waxy top.  It is not known if the underside is harry like P. stemaria.  Typically grown in a greenhouse, the above plant is grown outside and tolerates lower temperatures that either parent. most common problem reported is rot from too much watering. 

Both P. elephantotis and P. stemaria are found together in the forests of West Africa and need an 80F humid environment with temps above 50F so should probably be grown in a greenhouse.  The P. elephantotis is native to dry forests whereas the P. stemaria is reported to like frequent watering.  Nothing has been reported on the watering of the P. elemaria.  P. elemaria appears more tolerant to cold than its parents.  It grows out doors in So. California.


 


There is a cultivar of P. elemaria cv. sanchez that may not be deciduous.  Only slight browning of the shield fronds has been reported.  Whereas the P. stemaria has short lived shield fronds, and the P. elephantotis massive shield fronds which turn brown in the spring.  It is not known if the fertile fronds are harry on the underside like P. stemaria.  It may be the photos, but the shield fronds show a yellowish green near the bud.
