To Joseph Decaisne   15 February 1858

Melbourne bot Garden

15 Febr. 1958.

Much esteemed Sir

Being extremely anxious to extend the contributions for this garden for mutual exchange to all the principle gardens of the world, I take the liberty of forwarding to you a parcel of Australian seeds with the solicitation of returning to us seeds of such trees & shrubs as are likely to succeed without protection to grow in our climate. Particularly the plants of the shores of the Mediterranean Sea would be highly acceptable, very few of which are in our possession.

I shall endeavour to make up for your Government a collection of seeds of such plants, as would be desirable for introduction into Algeria, where the climate is so similar to ours.

I beg to enclose a fragment of Marsdenia? ceratostigma n. sp. from Moreton Bay with my desire of benefitting from your unrivalled knowledge of Asclepiadeae, and I hope you will kindfully inform me, whether it ought to be considered as a new genus (ranking between Stephanotis & Marsdenia) for which the name Arotostigma might be applied.1

Also I have the honor to enclose a fragment of Rhyncharrhena (n.g.) atropurpurea, a plant of extreme scarcity, discovered in Eastern tropical Australia during Mr Gregory's expedition,2 and of which on the place of discovery the bye-following notes (without application of the miscroscope) were made. Both these plants are not yet published3 nor a second species of Microstemma from N. W. Australia4 and other [new] asclepiadeae, which I gladly will send for your scrutiny if desired.

I did myself the honor of writing a reply to your extremely kind letter by the last mail and sincerely wish, that I may often yet be honored with a communication from so great a savant as your self.

Most humbly

yours

Ferd. Mueller

The seeds are forwarded by favor of Count Chabrillon, who is on his voyage to Europe.
