Crataegus 1741 



5. Var. punicea flore pleno, Loudon, Arb. et Frut. Brit. ii. 832 (1838), and 

 Trees and Shrubs, 377 (1842). 



'^zx. flore rubro pleno, Rodigas, in Flore des Serres, xv. t. 1509, fig. 3 (1862). 



Flowers double, pink. This is said by Loudon to have been imported about 

 1832 by Masters of Canterbury, and to bear flowers not so brilliant in colour as the 

 single crimson variety. It dififers from typical C. oxyacantha in the pubescent leaves 

 and calyx-tube, and is possibly a hybrid. 



6. Var. coccinea flore pleno, Paul, in Florist and Pomologist, vi. 117 (1867). 



Yax. flonbus coccineis plenis, Lemaire, in Illust. Hort. t. 536 (1867). 



Cratcegus monogyna, var. Pauli, Rehder, in Bailey, Cyc. Amer. Hort. i. 396 (1900). 



Flowers double, deep scarlet. This originated about 1858 in Mr. Christopher 

 Boyd's garden near Waltham Cross, as a single branch on a tree of the double pink 

 variety, which was about 25 years old and nearly 30 feet high. This branch 

 was observed to bear flowers of a deep scarlet colour, year after year, whilst all the 

 other branches on the tree continued to produce flowers of the original pink colour. 

 It was propagated by Messrs. Paul, who showed it at the International 

 Horticultural Exhibition in 1866, under the name "Paul's New Double Scarlet 

 Hawthorn," by which it is still known. 



7. Var. Gireoudi, Spath, Cat. No. 104, p. 89 (1899-1900). 



Young shoots pink, bearing new leaves, which are mottled with white and pink. 

 This is represented at Kew by a spreading bush about 6 ft. high, received from 

 Spath in 1899. 



8. Var. aurea, Loudon, Arb. et Frut. Brit. ii. 831 (1838). 



Var. xanthocarpa, Lange, Rev. Spec. Cratagi, 71 (1897). 



Fruits yellow. This variety, which has been in cultivation over a hundred 

 years, bears freely and is very showy. 



9. Var. leucocarpa, Loudon, Arb. et Frut. Brit. ii. 831 (1838). 



Fruit white. Plot, Nat. Hist. Oxfordshire, 158 (1705), mentions^ a tree with 

 white haws in a hedge near Bampton ; but it does not appear to have been 

 propagated, and this variety was unknown to Loudon. 



The following is either a geographical form or a closely allied species : — 



10. CratcBgus polyacantha, Jan, Elench. Hort. Farm. 8 {1826). 



CratcBgus oxyacantha, sub-species monogyna, var. polyacantha, Nicholson, Kew Hand-list Trees, 

 343 (1902). 



Leaves small, about f in. long and broad, tri-lobed. Young branchlets, petioles, 

 peduncles, pedicels, and calyx-tubes densely covered with white woolly pubescence. 

 This is a small shrub, native of Sicily and Calabria. It is in cultivation at Kew. 



1 Cf. Ray, Syn. Meth. 453 (1724). A form with fruit larger than usual, occurring in the south of France and Switzer- 

 land, has been distinguished as var. macrocarpa, Le Grand, Stat. Bot. Forez, 119 (1873), ex Rouy and Camus, Flore de 

 France, vii. 4 (1901), identical with C. macrocarpa, Hegetschweiler, Fl. Schwetz, 464 (1840).
