Eriosyce islayensis, often sold under the genus Islaya. It is the only 'Islaya' species; all the rest are variants of this one.

Islaya islayensis is also called Eriosyce islayensis. You see other species of Islaya sold but they are apparently all the same. They certainly look similar as I have 6 others! #cactusdotcom #cactus #cacti #cactusflowers #kaktus #cactos #кактус #кактусыцветут #kaktusz #カクタス https://t.co/NyBU4AXaij

Islaya longicarpa is really Eriosyce islayensis and if you compare with my previous post you will see it's very similar. #cactusdotcom #cactus #cacti #cactusflowers #kaktus #cactos #кактус #кактусыцветут #kaktusz #カクタス #uksucculent #ukcactus #cactiofinstagram #cactusgarden https://t.co/F8Ync3maKs
