Agave nizandensis is quite a rare species from Oaxaca, Mexico. It is a clumping Agave with elongated narrow leaves with a lighter-colored midstripe. Leaves have terminal spikes, but they are insignificant. Not particularly cold hardy. Should be kept absolutely dry with temperatures below 15ºC, or it is prone to rot. Best to not expose it to temperatures below 10ºC, but for short periods it is okay.
It's critically endangered in the wild.
