[Enclosure 1]

The propagation by seeds of different trees and shrubs’ varietys and their resultance:

1. Acer Pseudoplatanus foliis variegatis: Travelling with Mr. Linné, the late Director of our Royal Gardens, I did find near Aachen (Aix-la-Chapelle) in the Garden of a medicine a very fine looking exemplar of Acer Pseudoplat. foliis variegatis.³ The tree was nearly 1 foot big and the ground round the Acer covered with white spotted seedlings, what is most remarkables indeed, because the possessor did affirm me that it were the same appearance every year.

2. Acer Pseudoplatanus foliis purpureis,⁴ which has the under site of the leaves red coloured, exist also in our Botan. Garden at Berlin as a beautiful tree. Mr. Bouché, Inspector of the Garden, was so kind to show me last autumn some pots full of seedlings, where all the young plants did have the same peculiarity like the mother-tree.

3. Berberis vulgaris foliis purpureis,⁵ from this fine coloured shrub exist at Sanssouci a strong exemplar and I was sawing very often the fruits, but (between 100 plants) I was only so happy to find 1–2 red exemplars; all the others were green leaved like the mother plant.—

An argument, that no rule is without exception may be, that we did receive very often Seedlings for our nursery of trees etc. from Mr. Grundel at Offenbach and Mr. Dauveli at Orléans,⁶ where between 100 and more red leaved plants seldom one green leaved was discovered.—

4. Corylus Avellana foliis laciniatis (urticaefolia), I saw this shrub (at Magdeburgh in the Garden of Mr. Häneb) propagated by seeds and it was about $\frac{1}{3}$ of the seedlings constant, the other did have the common character.⁷

5. Corylus Avellana foliis purpureis has sometimes the affection so generate by seeds mostly red seedlings but also sometimes $\frac{1}{3}$ red plants, $\frac{1}{3}$ with red brown leaves and $\frac{1}{3}$ with common green leaves. The first case passed in the Garden of Mr. Vogel at Potsdam, the other in my garden at Sanssouci.⁸

6. From the common Daphne Mezereum (with red flower and berry), we did have in our nursery of trees etc also a variety with yellow flower and fruit — Daphne Mezereum fructa lutea.⁹ More then six times I was sawing the fruits of the last variety and allways I was so happy to bring up again plants like the mother shrub (without any exception.).—

7. Fagus sylvatica foliis purpureis ¹⁰ Seedlings I have seen not only in Germany also in Belgium and the resultance was: $\frac{1}{3}$ with fine red coloured, $\frac{1}{3}$ with rust-brown and the other $\frac{1}{3}$ with quite green leaves.

8. Some years ago I did receive by a Gentleman a great quantity of seeds, from Fraxinus excelsior monophylla (simplicifolia), which I was sawing directly. The resultance has been extraordinarily because between more then 3–400 seedlings were not more then about 30 exemplars, looking like the mother-plant, all the other seedlings were common ashs.—

9. From Quercus pedunculata var. pyramidalis ¹¹ I did saw also often the glans and mostly the seedlings has been again fine looking pyramidal trees, the rest allways more or less slightly or quite complete common Oaks.

10. Quercus pedunculata foliis argent. variegatis,¹² I did also propagate by glans but the essays has been not succeeding because between about 100 plants only two did have the leaves a little spotted.

11. Very interesting indeed has been the resultances of the Quercus pedunculatæ foliis argent. marginalis,¹³ one of the finest varietys, where all the leaves have small white edges and the glans also is white striped.

I was so glad to receive 30 Seedlings but all and every plant was covered with leaves so white as snow and curious fact the little oaks were expiring in some months, because the nature did not like to protect the existence of them.

12. Ribes nigrum crispum (aconitifolium) (spectabile) I propagated 8 years ago also by seeds and obtained $\frac{1}{3}$ common black currants, $\frac{1}{3}$ like the mother plant and $\frac{1}{3}$ with frizzled leaves, which was called by Prof. Koch Ribes nigrum apiifolium.¹⁴

The last again to propagate by seeds, was quite impossible because my seedling did never show a flower, he was a regular monstrosity and I was allways obliged to propagate by cuttings.

13. For to be sure, that berry varietys could be also propagated sometimes by seeds, I slected Ribes rubrum var. cerasiferum (Grosseille à cerise).¹⁵ In the fourth year all the seedlings did show their fruits and alltogether so also the leaves were looking like the mother plant.

14. Rubus laciniatus I was very often sawing nd between all the seedlings and the mother was never a difference, so that I believe it will be perhaps a pure species!— ¹⁶

15. Thuja orientalis var. aurea ¹⁷ is also sometimes propagated by seeds and a great quantity of the young plants has then the same originellity as the old plant.

16. Thuja occidentalis var. Wareana ¹⁸ was also propagated in our Botan. Garden at Berlin by seeds and all the seedlings did have a similar appearance as the mother tree.

17. Taxus hibernica (fastigiata.)¹⁹

A friend at England was so kind to give me one day a small portion of Seed, which rised in the second year, but also not one plant did have the character like T. hibernica. The were alltogether looking like the common Yew with the exception of 3 exemplars, growing more pyramidal like Taxus baccata var. erecta.

At least I mention yet two examples of 2 very known species of Spiraea, which I was propagating by seeds: Spiraea callosa and Douglasii.²⁰

18. Spiraea Douglasii one of our oldest red flowering Spiraees, I was allways obliged to propagate by cuttings, because between more then 400 seedlings scarsely 10 exemplars has been, which did have the same figure like Sp. Douglasii, the seedlings were representing the forms: Billardi, eximia, carpinifolia etc.²¹ so that I believe, we are not more in the possession of the right old Spiraea Douglasii or what also possible — it is only a variety.—

The same resultance was stated at Muskau in Prussia (Possession of His Roy. H. the Prince of Low-land.)²²

19. Spiraea callosa this nice and very much estimated Spiraea was propagated all and every year in our nursery in great quantity and allways the curiosity has been, that some exemplars (between 5-600) did have red grape-like flowers and not like all the other umbelliferous, also the leaves were differently looking.

Because the variety was trained at Sanssouci so Prof. Koch did give her the signification Spiraea Sanssouciana. Some times later we did receive from England Sp. Nobleana, trained at Bagshot (?) and Sp. Regeliana from Frankfurth trained in Mr. Rinz’s nursery, but all the three varietys seemed me to have the same mother— that is to say—Sp. Callosa!—²³

Climbers changing their character in an elder state:—

1. Hedera Helix the common Ivy with all his varietys is allways changing the physicomie, when he is beginning to show his flowers and it is a very curious fact that propagated in this period by cuttings the Ivy will not accept again his original character. We find this form announced in the Catalogues of the nursery men as Hedera Helix arbuscula.²⁴

2. Lonicera brachypoda has as a creeper allways more tender leaves but because the plant in our country will be very often attacked by the frost, so we find her sometimes cultivated in pots on sticks, 2-3’ long, where the leaves are changing their character in a manner that they are looking like evergreen as the leaves of a Viburnum Tinus.—²⁵

3. In a similar way as the first it is also the case with Decumaria barbara.—

4. Cissus acuminata, a fine looking climber from the Himalaya is allways in my country a very sensible plant and is to be covered in the winter. Some plants standing on a wall are at once producing on the top very notable leaves (Cissus acuminata. [symbol].) what is indeed very curious, because I never saw such a fact at the similar Cissus quinquefolia (Ampelopsis hederacea).²⁶

5. Ficus stipulata (a) is no dought the most interesting example of all because planted on the wall one our houses (for forcing beans) would not change her character till to the time where she was showing the fruits, then the now leaves at once were beginning to be larger and longer, so that no person would know again the Ficus stipulata²⁷

In our Botan. Garden at Berlin is such a shrub propagated by a fruit-branch in a pot, which is every year full of fruits and which will never return again to his true character.

The fact is almost incredible, but Mr. Bouché,²⁸ Inspector of the Roy. Botan. Garden at Berlin is capable to affirm the truth.—
