귀룽나무와 세로티나벚나무 비교 (FNA  검색표 참조함)

 

1.  엽연은 소둔거치로 내곡 또는 엽연에 압착한 느낌을 주는 거치;

     엽저는 좁은 쐐기 모양;  

     측맥은 15-30쌍;  잎 뒷면 측맥은 융기하지 않는다

     열매에 꽃받침이 숙존

     핵 표면은 평활

     ...........................................................     Prunus serotina 세로티나벚나무

1. 엽연은 소예거치로 거치가 경사 내지 개출:

    엽저는 넓은 쐐기 모양으로 대개 밑이 약간 파인 느낌을 준다;

   측맥은  6-18쌍; 잎 뒷면 측맥이 융기한다

   열매에 꽃받침은 조락하고 대신 화반만 남음

   핵 표면에 주름 있음  

.......................................................        Prunus padus 귀룽나무      

 

*  보충 :

대체로 세로티나벚나무 엽신은 길쭉하고 귀룽나무는 엽신 폭이 세로티나벚나무보다 넓다

Prunus serotina Ehrhart, Gartenkalender. 3: 285. 1784.

[name conserved]

Black or rum cherry, cerisier tardif ou d’automne, merisier

Shrubs or trees, not suckering, 40–400 dm, not thorny. Twigs with terminal end buds, glabrous or hairy. Leaves deciduous; petiole 2–23(–30) mm, glabrous or sparsely to densely hairy, usually glandular distally or at petiole-blade junction, glands 1–6; blade usually narrowly elliptic, oblong-elliptic, or obovate, sometimes lanceolate, rarely ovate, 2–13.5 × 1.1–6.5 cm, base cuneate to rounded, margins crenulate-serrulate to serrate, teeth ˂incurved or appressed˃, sharp or blunt, glandular or callus-tipped, apex usually acute to acuminate, sometimes obtuse, rounded to emarginate in var. alabamensis, ˂lateral veins 15–30 per side, flush abaxially˃, abaxial surface usually densely hairy along midribs proximally, sometimes glabrous or sparsely hairy, adaxial glabrous. Inflorescences 18–55(–90)-flowered, racemes; central axes (25–)35–160 mm, ˂leafy at bases˃. Pedicels 1–10 mm, glabrous or hairy. Flowers blooming after leaf emergence; hypanthium cupulate, 1.5–3 mm, glabrous externally; sepals erect-spreading to reflexed, semicircular, 0.5–1.5 mm, margins usually entire, rarely glandular-toothed, ˂rarely ciliate˃, surfaces glabrous; petals white, obovate to suborbiculate, 2–4 mm; ovaries glabrous. Drupes dark purple to nearly black, globose, 5–10[–25] mm, glabrous; ˂hypanthium persistent˃; mesocarps fleshy; stones subglobose, not flattened.

Varieties 4 (3 in the flora): North America, Mexico, Central America, South America; introduced in Europe.

Variety capuli (Cavanilles) Hatusima [subsp. capuli (Cavanilles) McVaugh] is known from Mexico (Chiapas, Jalisco, Distrito Federal, México, Puebla), Central America, and South America (Argentina, Bolivia, Colombia, Ecuador, Peru, Venezuela). It is distinguished from var. serotina by lanceolate to ovate-lanceolate leaves with decurrent bases (versus elliptic to obovate with obtuse to cuneate bases) and a long (to 2 cm), thin (1 mm) petiole; inflorescences tend to be subtended by 3 or 4 leaves [versus 2 (or 3), reduced in size], with a rachis relatively longer (greater than 15 cm), thicker, and flexuous compared to other varieties, and shorter pedicels (3–5 mm versus 5–10 mm, in var. serotina).

The characters given in the key usually allow easy separation of Prunus serotina from P. virginiana; some specimens from Arizona and southern Utah are difficult to determine. In that area, it is not uncommon for the sepals of P. virginiana flowers to lack the glandular teeth that are common elsewhere and thus mimic those of P. serotina. Variety rufula has thicker leaves that are also much shinier on both surfaces than those of P. virginiana and shorter petioles (2–15 mm versus 4–27 mm).

Compounding the confusion with chokecherry is a nomenclatural conundrum in which the epithet virginiana has been used for both chokecherry (the next species) and for black cherry (this species). The status of the two names Prunus serotina and P. virginiana was discussed by K. N. Gandhi et al. (2009), who proposed the conservation of both names.

Of our native Prunus species only P. serotina grows large enough to produce commercial lumber, which is highly prized for its fine grain and rich, warm, reddish brown color.
