This plant is not Aloe littoralis, which has longer, narrower, light blue-green-gray leaves with few spots. I'm not quite sure how the tag ended up there, but the leaves are not a match. I'm not quite sure what to call it though, especially since spotted aloes can be difficult to pin down. Maybe it would be best to move this image to the generic (parent) aloe page. What do you think?

MOBOT is usually pretty reliable about plant ids, but they're not infallible...I'll request a photo replacement move after the football game ...

I've seen more wrong ID's from MOBOT than any other supposedly reputable source. I quit using that a few yrs ago, though wrong names take nothing away from beautiful gardens.
