streamWrapper $form reference

[Clover13]

What is the $form reference in the following code for streamWrapper?  I have one site showing the streamOverview blurb and another that isn't but unclear what setting is influencing this?

 

<div class='ipsFlex-flex:11 sm:ipsMargin_bottom:half'>
  <h1 class='ipsType_pageTitle'>
   <span data-role='streamTitle'>{$stream->_title}</span>
  </h1>
  {{if $form}}
  <p class='ipsType_reset ipsType_normal' data-role='streamOverview'>
   <span data-role='streamBlurb'>{$stream->blurb()}</span>
  </p>
  {{endif}}
</div>

$form comes from a php file.

OK, I guess I'm trying to figure out why one site shows the streamBlurb and another doesn't and what is causing that.  Any idea there?

For now I just commented out the streamOverview on both sites so the customizations are consistent.
