What does a bonnet gourd look like?

This 1 seems to refer to Luffa, but does anyone have photos? I’d love to see what these bonnets look like, but unfortunately Google is not being very helpful. Gourds are inevitably much on my mind after my trip to PNG

LATER: And here it is, thanks to Eve Emshwiller:

Purslane possibilities

Screen Shot 2014-07-03 at 9.13.57 AMSharp-eyed readers may remember a recent Nibble about somewhat quixotic efforts to promote cultivation and consumption of purslane (Portulaca oleracea) in the US, driven more by necessity than conviction. Well, one particularly sharp-eyed reader pointed out that across the border, in Mexico, there’s a whole network of researchers within the Sistema Nacional de Recursos Fitogenéticos para la Alimentación y la Agricultura devoted to this unusual vegetable, which has some half dozen accessions in the bank to play with. There are 106 accessions in Genesys. Purslane researchers of the world, unite! You have nothing to lose but your mineral deficiencies.
