Platycerium Wandae

 

 

  Many lobes per fertile frond, one spore patch per lobe.
  One lobe is small and elevated, one s large and hanging down.

 

 

P. wandae is one of the 5 large platyceriums that include P. supebum, P. grande. P. wallichii & P. hulttumii.  P. wandae is considered the largest staghorn.  It is distinct by its size and it grows about 30 percent larger than a P. superbum.  The shield fronds are very upright and lobed along the top.  They form a basket.  The fertile fronds are like those of a P. holttumii, with two lobes, the smaller one is elevated.  Each lobe has a brown spore patch.

* Unconfirmed data.  The one known P. wandae growing in Southern California is in a greenhouse and has been thriving for 30 or more years.  I just obtained a P. hulttumii from Louisiana and it is still a young plant.  Next winter will be a test of how it survives in my greenhouse.

** Roy Vail reports that the 1997 International Fern Show in Los Angles had a mature P. wallichii
 

The photo on the right illustrates how vertical the shield fronds grow.  This is a young P. wandae, but the vertical characteristic is well displayed.  It looks like the fertile fronds have not started to form.

On the left you can observe the frills that grow around the growth bud. Click on photo for a larger image.  The photo is from Steven Lee Ankeneys Facebook post.   The shield fronds also form frills along the edge of the shield fronds.

Roy Vail reports that the P. wandae grows fertile fronds at a younger age than any of the other giant platyceriums.

P. wandae likes temperatures between 60 F and 100 F.  It will tolerate cold temperatures for a short period, but damage will occur below 40 F.   Like the P. superbum, it likes bright filtered shade, but should be grown in a greenhouse to keep the humidity high and eliminate extreme temperatures.

  This left photo is the best photo I have seen showing how there are two lobes with spore patches.  One is smaller and elevated above the second and has shorter fronds hanging down.  The second lope is below the first spore patch and is larger with much longer fronds hanging down.  You can click on the photo to see a larger image.

  The right lower photo also shows two spore patches, however they are old and have turned brown.  Notice how they are on top of each other.
