CRAT^EGUS 



9. CRUS-GALLI. 



19. Crus-galli, Linn. COCKSPUR THORN. Shrub or 

 tree, to 40 ft.: branches wide-spreading, rigid, often 

 pendulous, with numerous slender spines: Ivs. obovate 

 or oblanceolate, irregularly and sharply serrate, usually 

 rounded at the apex, quite glabrous, 1-2^ in. long, 

 often semi-persistent: corymbs glabrous; calyx-lobes 

 entire or minutely serrate: fr. usually globose, red, 

 with usually 2 stones; flesh thin and dry. May, 

 June: fr. late in Oct. Que., south to N. C., west to 

 Mich. S.S. 4:178. Em. 492. R.B. 1:116. G.F. 7:295. 

 G.C. III. 28:244, suppl. Sept. 29. A very decorative 

 species of distinct habit, handsome in bloom and with 

 showy, bright red fr., remaining on the branches often 

 until spring; the Ivs. assume a brilliant orange and 

 scarlet color in fall. Often used for hedges. Var. iner- 

 mis, Lange. Spineless form. Var. linearis, Ser. Lvs. 

 linear-lanceolate. Var. nana, Nichols. Dwarf form. 

 Var. pyracanthifolia, Ait. Lvs. elliptic or obovate, usu- 

 ally acute: fr. smaller, brighter red. W. N. Y. and Pa. 

 to Fla. and Tenn. S.S. 13:637. Var. saliciffilia, Ait. 

 Lvs. oblanceolate or lanceolate, thinner. Var. splen- 

 dens, Ait. (var. lucida, Hort.). Lvs. elliptic-oblanceo- 

 late, very shining. Var. ovalifdlia, Lindl. (C. pennsyl- 

 vdnica, Hort., not Ashe). Lvs. elliptic or elliptic-obo- 

 vate, less lustrous: fr. ovoid. B.R. 22:1860. Gn. 22, p. 

 146; 33, p. 468. This is probably not a variety of C. 

 Crus-galli, but a distinct species identical with one of 

 the recently described species of this group. 



20. Canbyi, Sarg. Shrub or bushy tree, to 20 ft.: 

 branches wide-spreading, with thick usually straight 

 spines: Ivs. oblong-obovate to elliptic, acute or obtuse, 

 coarsely and often doubly serrate above the middle, 

 glabrous, lJ^-3 in. long: corymbs glabrous; calyx- 



lobes entire or sparingly serrate: fr. subglobose or ovoid, 

 about J^in. long, dark crimson, with juicy flesh and 

 3-5 stones. May; fr. Oct. E. Pa., Del, Md. S.S. 

 13:638. 



21. fecfinda, Sarg. Small tree, to 25 ft.: branches

 to oval, usually acute, doubly serrate, with strongly 

 marked veins, l%-3 in. long: corymbs slightly villous; 

 calyx-lobes glandular-serrate: fr. subglobose to ovoid, 

 %-%in. long, orange-red, with thick flesh and 2-3 

 stones. May; fr. Oct. Mo., 111. S.S. 13:641. 



22. Arduennae, Sarg. Shrub or tree, to 20 ft.: 

 branches spreading, forming a round-topped head: 

 spines slender: Ivs. oblong-obovate, acute, acuminate 

 or rounded, crenulate-serrate from below the middle, 

 with obscure veins, l%-2^2 in- long: corymbs glabrous, 

 pedicels slender; calyx-lobes entire or slightly serrate: 



1 100. Crataegus punctate. No. 26. 



fr. ovoid, dull dark crimson, about J^in. long, with 

 1-2 stones. May; fr. the middle of Sept. Pa. to 111 , 

 Mich, and Ont. S.M. 373. 



23. Carrierei, Vauv. Small tree, to 20 ft., with spread- 

 ing branches and stout spines: Ivs. elliptic or oblong- 

 obovate, acute, pubescent below, glabrous above at 



length and lustrous, irregularly serrate, 3-4 in. long: 

 corymbs rather few-fld., pubescent; fls. large, with red 

 disk; calyx-lobes linear, serrulate: fr. bright orange or 

 brick-red, ovoid, about Hin. long, with 1-3 stones. 

 May. R.H. 1883:108. G.C. III. 21:118, 119. Proba- 

 bly hybrid between C. Crus-galli and C. mexicana, 

 originated in France. Possibly not different is C. Lav- 

 dllei, Herincq, described with larger subglobose fr. 



24. persistens, Sarg. Low tree, 12 ft. or more: 

 branches wide-spreading, with numerous stout spines 

 to 2 in. long: Ivs. lanceolate to oblong-obovate, acumi- 

 nate, cuneate at the base, coarsely serrate above the 

 middle, at maturity glabrous, dark green and lustrous 

 above, pale beneath, 2-3 in. long: corymbs slightly 

 villous; fls. over Min. across; calyx- lobes glandular- 

 serrate above the middle or entire; stamens 20, anthers 

 white; styles surrounded at the base by a broad ring 

 of pale tomentum: fr. ovoid or slightly obovate, crim- 

 son, not lustrous, over Hin. across; flesh thick and 

 mealy, with 2-3 stones. May: fr. in Oct. S.T.S. 2:190. 

 Of unknown origin, possibly a hybrid of C. Crus- 

 galli. Raised at the Arnold Arboretum. The Ivs. remain 

 on the branches unchanged until those of all the other 

 hawthorns have fallen and the frs. persist until late into 

 the winter. One of the most conspicuous of winter 

 fruiting plants.

 times nearly glabrous, tomentose below, lJ^-3^ in. 

 long: corymbs white-tomentose; fls. %in. wide; calyx- 

 lobes entire or with a few teeth at the apex; stamens 20, 

 with pink anthers: fr. ovoid to pyriform, orange or

 irregularly serrate, on the shoots often slightly lobed, 

 villous below, with impressed veins above, 2-4 in. long: 

 corymbs villous; fls. large; calyx-lobes entire: fr. pyri- 

 form or subglobose, dull red, dotted, about ^in. across,
