HEDEdMA (Greek, Sice'ff smej/). Lubliltm. Ameki- 

 CAN Pennvkoyal. This is a plant of no ornamental 

 value, but the seeds aro offered by our nurserymen to 

 those who cultivate the plant for its medicinal oil, which 

 is commonly sold in drug stores. It is claimed to be offen- 

 sive to mosquitoes, and the plant can be easily natu- 

 ralized in dry, sandy spots. It is common in woods and 

 along roads. The genus has about IG species, all Amer- 

 ican. The Pennyroyal of the Old World is Menilia Pu- 

 lei/iiim, sometimes cult, for its lvs. and tops, which are 

 used as culinary herbs. 



pulegioides, Pers. American Pennyroyal. Annual, 

 C-18 in. high: stem very slender, much branched, pu- 

 bescent : lvs. opposite, ovate to oblong-obovate, spar- 

 ingly serrate in the upper portion, mostly obtuse at the 

 apex and narrowed at the base, %-VA in. long: fls. in 

 axillary clusters; corolla purple, 2-lipped, the lower one 

 with 3 large lobes. July-Sep. B.B. 3:106. 



HfiDERA (ancient Latin name of the Ivy). Araliit- 

 ceiv.. Ivy. Ornamental evergreen climbing shrubs, with 

 alternate, entire or palmately 3-5-lobed, long-petioled 

 lvs., inconspicuous greenish fls. in terminal, peduncled 

 umbels, appearing in fall, and black, rarely yellow, red 

 orwhitish berries. SomesraaU-lvd. forms may hf. grown 

 North if protected during the winter, but must c.t tin- 

 larger-lvd. and variegated forms are too tcii.l. r ii.,,ili 

 of the middle states. The Ivy is a very valualilr |il,uii 

 for covering walls, rocks, trunks of trees and tnllis- 

 work, and sometimes climbs very high. It may also bo 

 used for covering walls in cool greenhouses, for screens 

 in drawing-rooms and for hanging baskets. It is a pop- 

 ular window-garden plant, enduring many uncongenial 

 conditions and thriving without bright sunlight. In shady 



places under trees it makes a handsome evergreen car- 

 pet, and is also often used for borders of shrubberies or 

 flowerbeds. It grows in almost any soil, but best in a 

 somewhat moist and rich one, and in shaded positions. 

 The climbing or creeping branches do not flower; fls. 

 are produced on erect, bushy branches, appearing on 

 old, high-climbing plants onlv. Prop, by cuttings of 

 half-ripened wood at any time of the year i 



UEDERA 



the open ground in fall ; gentle bottom heat will hasten 

 the development of roots considerably; also increased 

 by layers and by seeds. The slow-growing forms, espe- 

 cially the shrubby ones, are often grafted on cuttings of 

 strong-growing varieties. Two species in Eu., N. Afr 

 and Asia. Fls. perfect ; calyx 5-toothed ; petals and 

 stamens 5: ovary 5-celled: fr. a 3-5-seeded berry. Many 

 Araliads have been described formerly as species of 

 Hedera which are now referred to other genera. A good 

 popular monograph is Shirley Hibberd's "The Ivy: A 

 Monograph, comprising the history, uses, characteris- 

 tics, and aflinities of the plant, and a descriptive list of 

 all the garden Ivies in cultivation." London, 1872.
