years where the species has been found. Where it occurs 
it exhibits the propensities of a weed and has become 
amenable to a diversity of conditions, growing in clipped 
lawns, under shrubs, along ditches, and thriving equally 
in sun or shade. 
The behavior of Zeuvine strateumatica is remarkably 
unlike that of any other orchid I have observed. As is 
well known, our native terrestrial species are extremely 
fastidious. With few exceptions they exhibit intolerance 
of human contacts. Even though we endeavor to supply 
the delicate balance of soil conditions revealed necessary 
by scientific research they seem to resent attempts made 
to cultivate them in our gardens. Zeuaxine strateumatica 
behaves as if it were adapted to the disturbing influences 
usually associated with cultivated ground and this was 
strikingly evident in the Ormond ‘Tropical Gardens 
where the plants survive the clipping of lawns and the 
cultivation of the soil beneath shrubs. 
The roots of the plant are provided with endophytic 
fungi. From cultures made at the Biological Laborato- 
ries by John N. Porter, the fungal symbiont would seem 
to be aspecies of Rhizoctonia with typical monilioid con- 
idial chains. Attempts to germinate the seeds in associa- 
tion with this fungus have failed, but failure may be the 
result of the methods used rather than evidence of in- 
compatibility. The likelihood that the fungus isolated is 
a species other than the one on which mycorrhizal asso- 
ciation depends is of course a possibility. 
Zeuvine strateumatica is rather unusual in the brevity 
of its floral maturation in Florida. It comes into flower 
in January and ina very few weeks sets an abundance of 
fertile seeds. By the middle of March the withered stems, 
leaves and inflorescence have completely vanished. In 
early April | was unable to find a trace of the plant in 
the Ormond Tropical Gardens and transplanted colonies
