タラヨウ(3) 学名,西欧文献 ケンペル,ツンベルク,シーボルト&ツッカリーニ,パクストン&リンドリー,サバティエ&フランシェ,マキシモヴィッチ,

Ilex latifolia
CBM. Vol. 92 (1866)  TAB. 5597
この樹木は長崎を含めた西日本に多く,つやつやと大きな葉を一年中輝かせ,雌木は長い期間見事な赤い実をつけて目立つからであろう,多くの日本に来た欧州の植物学者に記録されている.

タラヨウを最初に記録に残した西欧人は,1690-92 年に長崎出島のオランダ商館に医師として滞在した★エンゲルベルト・ケンペルEngelbert Kaempfer, 1651-1716)で,その『廻国奇観』(Amoenitates Exoticae , 1712)の “Fasciculus V, 775” に「葉羅多 タラヨウ」という漢字名の他に「オニモチ(鬼黐)」と一般的に呼ばれ,真っ赤な小さな実をびっしりつける観賞価値が高い庭木として植えられている」と記し,カロルス・クルシウス(Clusius, Carolus, (1526-1609))の記録したセイヨウバクチノキと同じか?と記した.(左上図)
葉羅多 Taraijo, vulgo Onimotsj. Lauro-Cerasus, flosculis in luteum languentibus, tetrapetalis, numerosis, sub foliorum axillis in modum racemi confertis, fragrantibus; fructu pisi magnitudinis, rubente, umbilicato, quatuor intus granis, figurae seminum pyri, in orbem conglobatis. Ob sempiternam pulchritudinem in hortulis colitur. An Lauro-Cerasus Clusii?”

Lauro-Cerasus:カロルス・クルシウス(Clusius, Carolus, A.K.N. de l'Écluse, Charles (1526-1609))『パンノニア,オーストリア,およびその近隣の稀産植物誌』(Rariorum aloquot Stripium per Pannoniam, Austriam et Vicinas Historia 1583)より(右図)

現在でも有効な学名を与えたのは,リンネの高弟で,日本には1775 - 1776年の短い間滞在し,後にリンネの後を継いだ★カール・ツンベルク (Carl Peter Thunberg, 1743-1828) で, Syst. Veg., ed. 14: 168 (1784)”

“480. ILEX LATIFOLIA, A hardy evergreen tree, with long shilling leaves, greenish flowers, and small red axillary berries. Said to be a native of Japan. Belongs to Aquinifoils. (Fig. 240.)
This is a stout, stiff, evergreen, hardy tree, of great beauty. Every part is entirely free from hair. The shoots, which are deep green or tinged with violet, are somewhat angular near the ends. The leaves, which are from six to eight inches long, are deep green, not coloured at the edge, flat, oblong, acuminate, sharply and pretty regularly serrated, except at the base, which is entire, and gradually narrows into a petiole about three quarters of an inch long. The flowers are small, hermaphrodite, pale green, in very close axillary racemes, about as long as the leafstalks, and supported by short, ovate, acute, shining, car- tilaginous bracts. The berries, which ripen in February, are in short compact clusters, of a dull red colour, and nearly spherical; each contains from four to five stones, in which we have never succeeded in finding a kernel.
This valuable plant passes under the name of Ilex latifolia, by which Thunberg designated a small tree called, in Japan, No-Ko-Giri; but, if the statement of that botanist can be trusted, his plant must be different, for he says the leaves are egg-shaped, and three inches long by two broad, which gives them an entirely different outline from the species before us, the proportion of whose leaves is not three by two, but six or seven by two, a very material difference. Nevertheless, in the absence of any authentic evidence, we leave the garden name as we find it, especially since it is probably the I. latifolia of Zuccarini and Siebold (Floae japonicae familioe naturales, sect, i., p. 40), or I. macrophylla of Blume. According to the first of these authors, the leaves in the wild plant vary in form, being, on the same branch, oblong, ovate, or elliptical, acuminate or obtuse, and finely serrated, or slightly crenate.
The species nearly approaches the Ilex Perado of the Hortus Kewensis, a native of the Canaries, figured in the Botanical Magazine, t. 4079, under Webb and Berthellot’s name of I. platyphylla, another very handsome hardy shrub, differing from this in bearing clusters of large white flowers, and fruit more than twice the size of that of the present plant. There is no doubt that this I. latifolia, of which we believe two varieties are in cultivation, and which is plentiful in the nurseries, is as hardy as the common holly itself.

同じ英国で刊行され,現在でも続けられている★『カーチスの植物雑誌 (Curtis’s Botanical Magazine)Vol. 92 (1866) TAB. 5597 には,” ILEX LATIFOLIA. Broad-leaved Japanese Holly.” として花を付けたタラヨウと,実との美しい石版手彩色画(文頭図)とともに,記述されている.

“This noble Holly, though often supposed to be one of the later importations from Japan, has long been cultivated in the Royal Gardens, where it has stood without protection, trained against a wall, for many years, and quite uninjured. In the open air I have not observed it flowering, but it flowers abundantly in the Temperate House during June and July. In other places near London and elsewhere, it is cultivated as a standard ; and though I have never seen it luxuriant under such circumstances in the east of England, it no doubt succeeds perfectly in the west. It is a beautiful shrub, of a paler green than the common Holly, with similar berries, and the flowers are produced in round heads of a pale yellow-green colour. As a species it is extremely closely allied to an arborescent Himalayan species that I have found in the Sikkim province, which has however large berries containing a bony three to four-celled nut, which does not, as in this, break up into four nucules. I have native specimens of I. latifolia, collected near Nagasaki by the late Mr. Oldham, collector for the Royal Gardens, from whose seeds the plant.

DESCB. A tall evergreen glossy bush. Brunches very stout, angular, grooved when dry. Leaves three to seven inches long, oblong linear-oblong or oblong-lanceolate, acute, obtuse or acuminate, serrate, bright glossy-green above, paler and opaque below : nerves numerous, obscure when fresh. Flowers probably dioecious, in axillary, dense, subglobose, green clusters an inch to an inch and a half in diameter. Calyx with four short rounded lobes. Corolla cleft nearly to the base into four broadly oblong, obtuse, concave, pale-green lobes. Stamens usually larger than the corolla ; filaments filiformsubulate. Berries half to two-thirds of an inch in diameter, bright-red, globose or a little depressed, with a large persistent four-lobed stigma, containing four bony nuts. -  J. D. H

以上西欧人のタラヨウの記事は性状には非常に詳しく,植物学的に興味がそそられた樹木であったのであろうが,和本草家の気にしていた,傷をつけると黒く変色するという葉の特徴には触れていない.いくつかの日本での名称は記録しているものの,この木の和名「タラヨウ」の由来に興味がなかったからであろう.
