Dracsenas should be divided into two sections or 

 types for practical purposes: 



(1) The Tropical type: This includes the colored fo- 

 liage sorts and the garden hybrids, all of which can be 

 propagated from both root and stem-cuttings or joints. 

 All of them require a stove or warmhouse temperature, 

 and must be grown rmick, and never allowed to get pot- 

 bound until they an- as hirge as required; then they can 

 be allowed to get pot liound, and with liquid or other 

 stimulant and plenty of light will color well. 



(2) The Cortlyline or Subtropical or Australian type ; 

 This embraces the kinds known to gardeners as aus- 

 trails, Indlt'lsa, llneafa, sanf/uinea, anrea -striata, 

 Doueetianii .nmbraculltera ,RHmphil. Nearly all of these 

 are propagated from seeds, and require a cooler tem- 

 perature. 



Following are some popular current Drac»nas: Siin- 

 derlana makes not only a perfect center plant for table 

 jardinieres with small ferns and selaginellas, but it also 

 makes a fine large decorative plant by putting from 3- 

 5 in a 4-5 in. pot, and letting them get fairly well pot- 

 bound until each plant throws up shoots from the base; 

 then repot, and one will have a fine, large specimen in a 

 short time. Oodsefflana is a valuable plant for a hang- 

 ing basket, easily propagated from top shoots. Other 

 popular kinds are: Iforwoodlensls, ulbo-marginata, 

 termlnalls alba, Gladstonei (one of the most brilliantly 

 colored of the broad-leaved type), O-ullfoylei, Aner- 

 leyensls, Scottli, hybrida, metallica, ferrea, De-Smet- 

 iana, Vletorla -Reginw, Sanderlana, Gndsefflana, 

 gracilis. H. A. Siebrecht. 



DRACOCfiPHALUM (Greek, dragnn's head, from the 

 wide-open moutlis of the flowers). LabiAt(f. This 

 genus contains a few hardy herbaceous peretmial plants 

 of the mint family, of easy culture and of minor im- 

 portance. The whorls of fls. are distant or crowded into 

 spikes or heads, the colors blue or some shade of pur- 

 ple. The genus has altogether about 30 species, from 

 Europe, especially the Mediterranean region; also Asia 

 outside the tropics. All the species described below are 



DRACOCEPHALUM 



erect, but some others are diffuse : uppermost lvs. like 

 the lower ones or reduced to bracts. Very closely allied 

 to Nepeta. Sandy loam, moderately rich, and a rather 

 moist, partially shaded situation will suit these plants 

 best. In a sunny, dry border they are never very 

 showy; the fis. are of short duration, and are seldom at 

 their best except in very moist seasons. Prop, by di- 

 vision or seeds. 



734. Dracunculus vulgaris (X %). 



.\. Lrs. entire, imt cut in imi) irag. 

 Ruyschianum, Linn. Stems slightly pubescent: lvs. 

 linear-lanrroiatc, glabrous: bracts ovate-lanceolate, en- 

 tire; whorls in somewhat interrupted spikes: fls. 1 in. 

 long, puriili-ih hlue or purple: anthers villous. Siberia. 

 Var. Japbnicum, Hort., has white fls. shaded with bhie, 

 and is a distinct improvement. G.C. II. 12:167. — Ac- 

 cording to Vilinnrin, this species has been sold as D. 

 Altaie^ise (see D. grayidlfloritm). 



AA. Lvs. deeply S-5-cleft. 

 Austriacum, Linn., has the habit of the above, and be- 

 longs to the same subgenus Ruyschiana, but the lvs. 

 are divided and more distinctly revolute at the margin. 

 About 1-1^ ft. high : fls. blue, IK in. long and more. 

 July, Aug. Eu., Caucasus. 



AAA. Lvs. cut only at the inargin, mostly crenate. 

 B. Whorls crowded together into spikes or heads. 

 0. Color of fls. blue: lvs. not wrintcled. 

 grandifldrum, Linn. (D. Altaiinse, Laxm., but plants 

 in trade under this name are said to be D. Suyschiana). 

 About 1 ft. high. Root-lvs. long-stalked, oblong, notclies 

 at base: stem-lvs. few, short-stalked, ovate, not notched 

 at base, the uppermost still more rounded: whorls in 

 spikes 2-3 in. long, the lowest whorl usually at some dis- 

 tance: fls. 2 in. long. June, July. Siberia. B.M. 1009. 

 P.M. 13:51.

 stem pubescent instead of pilose above, root-lvs. more
