The plants, just received from you, dear Mr Tyson, I have named at once, so far as this could be done quickly. Some require dissection, to make out the full name; some few are new , and one of the best will be named after you.

M named Hemigenia tysonii in B93.11.05.

For many your collection gives us a new locality. I am glad, that you have an eye also for minute plants. Please collect also all sorts of floating or submerged plants , as the aquatics of your region have been very little studied. If it was possible for you to induce any settler on the Upper Ashburton-River

North-western WA, inland from Exmouth Gulf.

to gather plants also, then many of your species could probably be traced still further north, perhaps even into the tropic region. Try to get as many people as possible to collect north and east of you, so that my geographic tables of the West Australian plants may get completed.

Tyson lived at Mt Narryer, inland from Sharks Bay, WA.

May I ask also, that you collect a seed-bearing specimen also of any of those plants, of which I have not yet given the full name, as that will facilitate the examination. Mount Augustus on the Lyons-River must have altogether new plants on its top, as it is so high.

4

c. 500 km east of Carnarvon, WA; 1100 m above sea level, 715 m above the level of the plains.

I suppose you could not go there yourself, but might get someone to collect all that grows at and near the top.

Notes on pasture-plants very valuable.

No letters from Tyson to M have been found.

Please collect also all grasses and Rushes
