Pear

Van Marum

Origin / History

Originated with Van Mons (Downing; Hedrick; Bunyard). Bunyard records it as a seedling of Van Mons that first fruited at Louvain in 1820, named after the chemist Van Marum; Hedrick gives the origin date as 1823. Bunyard notes that "the name Grosse Calebasse is now so firmly established in this country that it is probably impossible to revert to its correct original name." Elliott classes it as foreign. First published reference cited by Hedrick is Pomologie de la France 3:No. 125, Pl. 125 (1865).

Tree

Vigorous grower, productive (Downing; Hedrick). A very early and productive bearer on pear, with the fruit always fair (Elliott). Young wood reddish brown (Downing). Bunyard describes growth as moderate, rather upright, with fair fertility. Veitch's catalog calls it "a regular good bearer" that "requires a warm position." Bunyard adds: leaf elliptical, little up-folded, twisted, shallow, serrate.

Fruit

Size: Large to very large (Downing); large (Elliott; Thomas); enormous, 4¼ by 7 inches (Bunyard); very large, sometimes measuring six inches long (Hedrick).

Form: Oblong pyriform (Elliott; Downing; Hedrick); pyriform with a long neck (Thomas); long calebasse, uneven (Bunyard).

Stem / Stalk: Long (Elliott); rather long and slender (Downing; Hedrick); moderately long, very stout and fleshy, continued (Bunyard).

Cavity: Flattened (Downing; Hedrick).

Calyx / Eye: Large (Elliott; Downing; Hedrick); large, open (Bunyard).

Basin: Regular, shallow (Downing; Bunyard; Hedrick).

Skin / Color: Sources differ on color. Elliott: dull greenish yellow (and in his "Calebasse Grosse" entry, yellowish, dull green). Downing: yellow, rarely with a little red. Thomas: bronze-colored. Hedrick: yellow. Bunyard: skin rough; color entirely covered with a fine dark brown russet with an occasional red flush.

Flesh / Flavor: White (Elliott; Downing); white, liable to rot at the core, half melting, not very juicy, but sweet and pleasantly perfumed; rated "Good" (Downing). Hedrick: white, apt to rot at the core, half-melting, not especially juicy, sweet, aromatic; rated "fair to good." Thomas: coarse, fibrous; not juicy, pleasant. Bunyard: greenish, white melting, of good flavour in a warm season, extremely juicy. Veitch's catalog: tender flavour, melting and luscious, choice fine fruit. Elliott calls the flesh "hardy" and rates flavor as "good," noting that "its bearing, its recommendation."

Core / Seeds: Liable to rot at the core (Downing; Hedrick). Otherwise not described in source.

Season

October (Elliott; Downing; Bunyard; Hedrick). Late autumn (Thomas).

Uses

Exhibition or dessert (Bunyard). Baking (Thomas).

Subtypes / Variants

Not described in source.

Other

Bunyard records dimensions of 4¼ by 7 inches; Hedrick notes the fruit sometimes measures six inches long. Bunyard specifies that good flavor depends on a warm season, and Veitch's catalog likewise notes the variety "requires a warm position." Elliott's volume contains a brief separate entry under "Calebasse Grosse" (Monstrous Calabash): "Foreign. Large, pyriform, yellowish, dull green. October."
