26/4/82.

Soweit wie ich erinnern, lieber Herr Tepper, war , FvM. N. 610 noch nicht in Südaustralien gefunden, da es so leicht für identisch mit Cl. Filum gehalten wird. Vielleicht können Sie noch zeitig genug diese Pflanze den neuen im Drucke zu fügen. Ich hätte gern davon einige ganz reife Samen.

Ihr

Ferd. von Mueller.

614. Smith dessen älterer Name E. gracilis ist.

618 ist merkwürdig.

Diese Drosera steht in demselben Verhältniss zu D. Whittackeri als in West Australien die blattlose D. squamosa zu D. erythorrhiza.

Beobachten Sie gefälligst diese Art genau; vielleicht sprosse sie schnell empor nach langer Dürre und starken Regen, während den Grund noch sommerwarm war, u so bildeten sich die Blüthen nicht aus. Die Structur der Blumen scheint dieselbe zu sein als die von D. Whittackeri, wenn nicht etwa die Petala schmäler sind. So früh, Anfangs April , habe ich D. Whitackeri nicht blühen sehen. Ich bitte eine Anzahl Blumen geöffnet separat zu pressen u auf die Frucht später zu achten; es mag etwas N eues sein u dann könnte die Art D. aphylla gennant werden. Sie haben dort die beste Gelegenheit beide zu vergleichen und dadurch würde auch weiteres Licht auf D. squamosa geworfen werden.

Wieviel noch zu beobachen ist zeigte sich mir kürzlich bei und , wie ich solche für den Census der Pflanzen Arten Australiens bearbeitete. Bentham hat 16 Arten von M. u 6 von B., anstatt davon habe ich nur 11 von M. aber 8 von B. obwohl keine neue Art hinzukam. Man darf wissenschaftl. Untersuchungen nicht überstürzen !, wenn solche haltbar sein sollen.

Blüthen schon Exemplare in März?

As far as I remember, dear Mr Tepper, FvM no. 610

See M to O. Tepper, March 1882 (in this edition as 82-03-00b).

had not yet been found in South Australia, because it is so easily regarded as identical to Cl. filum. Perhaps you can still add this plant to the new ones in the press. I should like to have some quite ripe seeds of this.

Your

Ferd. von Mueller.

See M to O. Tepper, March 1882 (in this edition as 82-03-00b).

Smith, the older name of which is E. gracilis.

618 is remarkable.

This Drosera stands in the same relation to D. Whittackeri as the leafless D. squamosa to D. erythorrhiza

D. erythrorhiza?

in Western Australia.

Kindly observe this species closely; perhaps it germinated quickly after long dryness and heavy rain, whilst the ground was still warm from summer, and so the flowers did not form. The structure of the flowers seems to be the same as that of D. Whittackeri, unless the petals possibly are narrower. I have not seen D. Whitackeri bloom so early, beginning of April . I ask you to press a number of flowers separately opened and to pay attention to the fruit later; it may be something new and then the species could be named D. aphylla. You have the best opportunity there to compare both and thereby further light would also be thrown on D. squamosa.

How much is still to be observed was shown to me recently in the case of and , as I worked on them for the Census of plant species of Australia.

Bentham has 16 species of and six of ,

Bentham (1863-78), vol. 1, pp. 115-21, 122-5.

instead of which I have only 11 of but eight of , although no new species were added. One should not rush into scientific investigations, if they are to be tenable.

Do specimens bloom as early as March?
