29. peduncull,ta,Ehrh. ( Q.Bdbur,Ya.r.pedHnculcita, DC. 

 Q. Robur, Linn., partly. ^>. femina, Mill.). Figs. 2038, 

 2048. Tree, to 120 ft., with stout spreading branches 

 forming a broad round-topped head: Ivs. short-petioled, 

 auriculate at the base, oblong-obovate, with 3-7 rounded 

 lobes on each side, quite glabrous, dark green above, 

 pale bluish green beneath, 2!^-5 in. long: fr. 1-7 on 

 slender peduncles; acorn ovate or ovate-oblong, about 1 

 in. high, embraced about one-third by the hemispherical 

 cup. Eu., N. Afr., W. Asia. G.C. III. 24:201; 25:168. 

 — More than 40 varieties are cultivated in European 

 nurseries and collections; some of the most important 

 are the following: Var. Concdrdia, Lemaire. Lvs. 

 bright yellow. I.H. 14:537. Var. contbrta, Hort. A 

 form with twisted branches and crowdedlvs. of ir- 

 regular shape ; of slow growth. Var. fastigislta, DC. 

 With upright branches forming a narrow columnar 

 head. G.C. II. 19:179. Of the same habit are var. fas- 

 tigi^ta cupressoides, Hort., with narrower lvs. Var. 



2051. Variation in the leaves of Live Oak. 

 {Qxiercus Virginiana.) No. 37. Nearly natural size. 



fastigriita ailreo-punctiltawith yellowish spotted foliage. 

 Var. iastigiata viridis with lvs. of darker green. Var. 

 heterophylla, Lond. (var. comptonkvfolia, Hort.) with 

 narrow, elongated, slightly or crenatcly lobed, some- 

 times almost entire leaves. Var. filicifblia, Lem. (var. 

 pectindta, var. lariniiita, var. asplenifolia, var. doumiti, 

 Hort.). Fig. 2049. Lvs. deeply divided often almost 

 to the midrib in narrow linear lobes, with crisp mar- 

 gins. G.(\ II. 14:032. I.H. 1, black figure not num- 

 bered opposite plate 33. R.H. 1894, )>. 17. Var. p6n- 

 dula, Loud. With pendulous Itranclics; a form witli 

 more slender and more decidedly w('('i)ing branches 

 is var. Dauvissei, Hort. Var. purpurflscens, DC. 

 (var. purpurea, Loud.). With the lvs. l>right pur- 



ple when young, becoming almost green at length or as 

 in the forms distinguished as var. atropurpdrea and var. 

 nigra, Hort., the color is more intense and retained 

 through the whole summer. F.8. 17:1763-84. Var. 

 variegata, Endl. There are a number of variegated 

 forms, but of no great ornamental value; the most cult, 

 are: aJho -variegata, argenteo-picfa , a ttreo - variegata , 

 Joreauensis maculdta, tricolor. 



30. sessiliflora, Salisb. {Q. Ebhur, var. sessiUflbra, 

 DC. Q. Mbbuv, Mill.). Similar in habit to the former, 

 but limbs less spreading and head less broad : petioles 

 %-% in. long: lvs. rounded or cuneate at base, obovate 

 or obovate-oblong, with 5-9 rounded lobes on each side, 

 somewhat glossy above, pale and glabrous or slightly 

 pubescent on the midrib beneath. 2K-5 in. long: fr. 

 almost sessile, usually somewhat larger than those of 

 the preceding species. Europe, W. Asia to Persia. A 

 very distinct variety is var. mespilifolia, Wallr., with 

 almost entire lvs. Var. purpurea, Hort., has the lvs. 

 purplish when young. — ^. sessiliflora is less common in 

 cult, than the last. Both are usually called English 

 Oak and ai'e often considered as mere subspecies of Q. 

 Rohur. 



31. lanugindsa, Thuill. (Q. puMscens,V^\\\A.). Tree, 

 to 40 ft., but sometimes remaining shinibby: branches 

 tomentose when young: lvs. pinnately lobed or pinnati- 

 fid, with 4-8 pairs of obtuse or acute lobes, glabrous 

 above, pubescent or tomentose and grayish green be- 

 neath, 2-4 in. long: fr. almost sessile; acorn ovoid, K- 

 1 in. long, enclosed about one-half by the tomentose 

 cup; scales closely appressed. M.and S.Eu., W.Asia. —A 

 very variable species, often shrubby, growing mostly on 

 dry, rocky and often on limestone soil; the more south- 

 ern forms of it are tender. Var. Hartwissiana, Dipp. 

 (Q. Hartivissidna, '^tftx.). Lvs. small, rather acutely 

 lobed, yellowish tomentose beneath. Var. p^ndula, 

 Jacq. ( Q. ^gilops, var. phulala and Pseudaegilops phi- 

 diila, Hort.), with pendulous branches and densely 

 tomentose lvs., resembles the following species and is 

 supposed by some authors to be a hybrid between the 

 two. 



32. Tdza, Bosc [Q.Pyreyiciica, Willd. Q. camdfa and 

 criiuta, Hort.). Tree, to 40 ft., with slender branches; 

 branchlets yellowish tomentose: lvs. pinnatifid half 

 way to the middle or more, with rather narrow and acute 

 lobes, pubescent above, yellowish or grayish tomentose 

 beneath, 3-5 in. long: fr. short or long- peduncled; 

 acorn. oblong, embraced one-third to one-half by the to- 

 mentose cup ; scales loosely appressed, rather large. 

 Spain. S. France. Var. p6ndula, Dipp., with pendulous 

 branches. — Somewhat tender north. 



33. conf§rta, Kit. ( Q. Pannouica, Hort. Q. Hungdrica, 

 Hubeny). Tree, to 120 ft., with gradually spreading 

 branches forming a round-topped, open head; bark 

 rather light brown: lvs. very short-petioled, auriculate 

 at the base, obovate, deeply pinnatifid, with 5-7 pairs of 

 often toothed lobes, dark green and almost glabrous at 

 length, pale and tomentose beneath, 4-7 in. long: fr. 

 short-peduncled; acorn ovoid-oblong, embraced about 

 one-third by the cup; scales rather large, loosely ap- 

 pressed. Italy. S. E. Eu. G.C. II. 5:85. -Pretty Oak 

 with handsome dark green foliage; hardy in Mass. but 

 seems not reliable farther north. 



34. C6rris, Linn. Turkey Oak. Tree, to 120 ft., with 

 rather short spreading branches forming a broad pyra- 

 midal at length often irregular open head: lvs. oblong 

 or obovate-oblong, pinnatifid, with 3-8 pairs of entire or 

 few-toothed lobes, dark green and somewhat rough 

 above, grajish pubescent or almost glabrous beneath at 

 length: fr. short-stalked, ripening the second year; acorn 

 oblong-ovate, to \% in. long, embraced about one-lialf by 

 the large mossy cup. S.E. Eu.,W. Asia. Mn.3:10ti. Gn. 

 27, p. 476, 477. — Handsome Oak with dark green foliage 

 and of pyramidal habit when young, but not quite hardy 

 north. Easily recognized even in winter by the slender 

 subulate scales surrounding and exceeding the winter- 

 buds. Var. Austriaca, Loud. Lvs. longer-petioled, less 

 deeply lobed, or almost sinuately dentate with short, 

 acute, entire lobes. For Q. Austriaca se»ipervire}is, see 

 Q. Turneri in supplementary list. Var. lacini^ta. Loud. 

 Lvs. deeply pinnatifid, often almost to the midril> 

 divided into narrow oblong lobes. There are hybrids
