form 'Higurashi' as well as 'Fugenzo' may show this deviating leaf shape, but the latter less frequently than 'Ojochin' or 'Higurashi'. Prunus 'Ojochin' Less current synonym: Prunus serrulata f. bullata Description: Tree umbrella-shaped, to 8 m high and 10 m wide. Young foliage slightly bronze. Serration single, remarkably coarse and with awntipped teeth. Fully developed leaves often lack the acuminate top. Teeth without glands. Stipules medium divided, 1319 mm long. Corymbose inflorescence, with three to five or even seven flowers. Peduncles 1.54.0 cm long. Pedicels 1.52.5 cm long. Flower in bud soft pink, becoming practically white with a light pink shade when completely opened. Flower 5.05.5(6.0) cm in diameter, large, opening to a flat plane with slightly folded petals. Petals five, occasionally one to three or up to six petaloids extra, orbicular and wavy at the edge, emarginate at the top, 2328 Ă— 2025 mm. Pistil one, perfect, about 12 mm long, as long as or slightly longer than the longest stamens. The calyx is campanulate to funnel-shaped, 7 Ă— 5 mm, with a faint pink tinge; there is a distinct transition from pedicel to calyx. Sepals are elongated, narrowing to the base, 12 Ă— 6 mm (at the base 4.5 mm), with a faint pink tinge, unserrated. Flowering season is from late April to early May. 'Ojochin' has a triploid set of chromosomes (2n = 24). 'Okiku-zakura' 'Okiku-zakura' ( is "big chrysanthemum-cherry") is rarely mentioned in any Japanese source, is never described, and is named only in lists of large collections like the one of (ca. 1842), or ranked as "rare and newly formed" in the source Sakurabon (1910). The Yokohama Nursery Company offered it for export in the 1930s. Trees are not found in Japanese collections at present, but may be seen in the Rombergpark in Dortmund, Germany, in the Belgian arboreta at Hemelrijk and Kalmthout, and in the Belmonte Arboretum in Wageningen, Netherlands. Jefferson (1984) says it is in cultivation in the United States. One would expect a big chrysanthemum-cherry to have large flowers tightly set with many petals, as is typical of chrysanthemum-flowered cultivars, but 'Okiku-zakura' has in fact no more than about twenty petals. The flowers are of a perfect shape, showing themselves at their best when
