Rory Stewart reviews ‘Aleppo Observed’ by Maurits H. van den Boogert · LRB 16 February 2017

Behind a paywall, alas, but trust me, this is a cut-and-paste quotation:

> And although van den Boogert is more disparaging of the Russells’ ichthyology – ‘based almost exclusively on what they were served at the consular table, and possibly what they observed in the stalls of the fish market’ – he cannot fail to be impressed by their catalogue of more than seven hundred Syrian plants, two of which, a sage and a milk-vetch, are now named the Phlomis Russeliana and the Astragalus
Russell.

Which just goes to show. You can walk across Afghanistan, be UK Minister of State for International Development, wear your extensive learning as lightly as you please and still screw up scientific names.

[Scientific names are strong proper names](https://www.jeremycherfas.net/blog/eagles-point-the-way), which take no *the*.
