Glossary

apex
(pl. apices) Tip. apical At the apex.
glabrous
Lacking hairs smooth. glabrescent Becoming hairless.
glaucous
Grey-blue often from superficial layer of wax (bloom).
hybrid
Plant originating from the cross-fertilisation of genetically distinct individuals (e.g. two species or two subspecies).
midrib
midveinCentral and principal vein in a leaf.
subspecies
(subsp.) Taxonomic rank for a group of organisms showing the principal characters of a species but with significant definable morphological differentiation. A subspecies occurs in populations that can occupy a distinct geographical range or habitat.
synonym
(syn.) (botanical) An alternative or former name for a taxon usually considered to be invalid (often given in brackets). Synonyms arise when a taxon has been described more than once (the prior name usually being the one accepted as correct) or if an article of the International Code of Botanical Nomenclature has been contravened requiring the publishing of a new name. Developments in taxonomic thought may be reflected in an increasing list of synonyms as generic or specific concepts change over time.

A deciduous tree or shrub up to 20 ft high; young shoots clothed at first with pale brown silky hairs; becoming glabrous and greyish the second year. Leaves oval, oval-oblong and obovate to roundish; rounded or abruptly pointed at the apex, wedge-shaped or rounded at the base, 3 to 7 in. long, 2 to 512 in. wide, glabrous and bright green above, slightly glaucous and at first very velvety beneath; stalk 34 to 212 in. long and, like the midrib, densely silky-hairy. Flowers saucer-shaped, white, fragrant, 4 to 5 in. wide, produced at the end of young leafy shoots on a stalk 1 to 2 in. long in June; tepals usually nine, oblong-obovate, 1 to 2 in. wide. Stamens numerous, 25 in. long, rosy-crimson. Fruits pendulous, cylindrical, 3 in. long, 112 in. wide, pink; seeds at first pink, ultimately scarlet.

Native of W. Szechwan, China; discovered and introduced to the Arnold Arboretum in 1908 by Wilson. It was found by him at altitudes of 7,500 to 9,000 ft and is perfectly hardy. Introduced to England through Messrs Chenault’s nursery at Orleans in 1920 and distributed under the name “M. nicholsoniana”. The magnolia to which that name was originally given is now regarded as a form of M. wilsonii (q.v.).

M. sinensis is a beautiful magnolia which thrives on chalky soils and is quite hardy (the original grafted plants imported from Chenault’s nurseries had the reputation of being difficult and somewhat tender, but this is perhaps accounted for by the use of an unsuitable stock.) Its spreading habit makes it less suitable for small gardens than M. wilsonii.

From the Supplement (Vol. V)

In his treatment of Magnolia (op. cit., p. 279), Dr Spongberg reduces M. sinensis to the status of a subspecies of M. sieboldii.

[M. × highdownensis] – According to Dr Stephen Spongberg (op. cit. pp. 277-8), the Highdown magnolia (and others like it which he saw on a visit to Britain) falls within the normal variation of M. wilsonii, of which M. × highdownensis Dandy thus becomes a synonym. As noted on page 665, the Highdown magnolia came from Caerhays in 1927, and was from a pan of seedlings whose label had been lost. There is an interesting possibility that they had been raised from seed of M. wilsonii collected in Yunnan. But Dr Grierson, who kindly consulted the accession books and specimens at Edinburgh, could find no evidence to support or disprove this suggestion.

M. sinensis × M. wilsonii. – Even if the Highdown magnolia is not of this parentage, it would be surprising if such a hybrid had not arisen in cultivation, and almost certainly it has done so at the Chateau de la Fosse in France. One of the seedlings, raised by Mrs Lort-Phillips, has been given the clonal name ‘Jersey Belle’ (Int. Dendr. Soc. Year Book 1981, pp. 120-21 and 1984, pp. 118-19).


M × highdownensis Dandy

A probable hybrid between M. sinensis and M. wilsonii. Young wood darker than in the former but lacking the purple tinge characteristic of the ripe stems of M. wilsonii. Leaves up to 7{3/4} in. long, 4 in. wide, elliptic or oblong-elliptic, acute or acuminate at the apex, rounded or cuneate at the base (thus they are very distinct from the leaves of M. sinensis and more like those of M. wilsonii, though somewhat larger and the leaves on the extension growths more perfectly elliptic); they are covered fairly densely beneath with white hairs. Flowers as large as those of M. sinensis.The original plants of M. highdownensis were received by the late Sir Frederick Stern in 1927 from J. C. Williams of Caerhays. They were seedlings from a pan whose label had been mislaid, so the seed-parent of the Highdown plants is unknown.The first description of these hybrids was given by Sir F. Stern in a note in New Flora and Sylva, Vol. 10, pp. 105-107, headed ‘M. sinensis × wilsonii’. The name M. × highdownensis was published by J. E. Dandy in Journ. R.H.S.,Vol. 75, pp. 159-161. Mr Dandy, who is the leading authority on the genus Magnolia, gave the following reasons for his belief that the Highdown magnolia is M. sinensis × wilsonii. First, it is intermediate between the two species. Secondly, the seeds came from a garden (Caerhays) in which both species had flowered. Thirdly, it is not matched by any specimens collected in the wild.
