Broccoli and kale are both brassica oleracea and are included under cabbage (another cultivar of the species). It has support for aliases though, so I don't get why it doesn't use that in this case. Broccoli is my archetypal brassica and I always get hung up when it isn't there.

Brassica oleracea is such a fascinating species by the sheer number of unrecognizably different vegetables we've cultivated that all technically remain the exact same species (it's way, way more than you'd think). If you've never looked at the table on wikipedia, please scroll down and take a look!

This also tripped me up. I didn't think to try cabbage. I did think to try brassica which is my preferred way of referring to the species.
