Hairy-Tongued. Lasioglossum calceatum, Sweat Bee, on Common Fleabane, Pulicaria dysenterica, Hortus Botanicus, Amsterdam, The Netherlands

It wouldn't surprise me if Great Carolus Linnaeus had difficulty in pronouncing the English 'th'. His tongue like that of many non-native speakers was not subtle enough - hairy, as it were - for that sound. There is of course a story to why I think this...

It has everything to do with how Linnaeus first describes this pretty Common Fleabane, Pulicaria dysenterica. In the Flora suecica (1745) his description includes the interesting observation that our Fleabane saved the lives of many Russian soldiers in the Russo-Persian War (1722-1723). They used it as a medicine against dysentery. How exactly it's not said: it might have been through oral ingestion or else by way of its smoke; whatever the case, either the fleas (Pulex) or their effects - bacillary dysentery caused by transmitted Vibrio cholerae - were stymied in their run.

Whence Linnaeus's knowledge? Well, from one James Francis Edward Keith (1696-1758), a Scottish mercenary who fought for Prussians and Russians and anyone who'd have him. You get the picture: 'Keith' must've been a problem for Linnaeus to pronounce; perhaps he never met the man and only corresponded with him. In any case, his Flora suecica prints the General's name as 'Keit.

As far as I know, Keith did not take part in that Russo-Persian War; but he did play a heroic role in the Russo-Turkish War of 1741-1743. I wouldn't be surprised if his experience with our Pulicaria derives from that exercise and not from the earlier one. Possibly Linnaeus got that wrong as well, or otherwise Keith told him what he'd himself heard about the Persian expedition.

Here in the peaceful Hortus Botanicus this afternoon I saw this pretty Lasioglossum - Hairy- or Rough-Tongued Bee - calceatum on Bright Yellow Fleabane. Look at it's pretty reddish abdomen (and let's not be reminded of the less than savory sanguinary effects of dysentery).
