HALESIA 



are rather short-lived, except in var. Meehani. Prop, 

 most commonly by layers, also by root-cuttings in spring 

 and autumn; and by seeds, which should be kept con- 

 stantly moist, as they rarely germinate until the second 

 year if allowed to dry. H. diptera is hardy as far north 

 as Philadelphia, but of doubtful hardiness farther north, 

 though it may become acclimatized. Thrives best in a 

 cool, deep loam. Prop, by seeds, which should never be 

 allowed to dry, and by grafting on U. tetraptera. 



tetrdptera, Linn. Fig. 1016. A small tree or shrub 

 8°-10°, whose fls. resemble those of a snowdrop. Lvs. 

 ovate or ovate-oblong, finely serrate, dark green and 

 glabrous above, pale green and stellate-pubescent be- 

 low, 2-4 in. long: fls. in lateral clusters of 2-i ; co-

 soidal, longitudinally 4-winged, 1-lK in. long. Va. S.

HALIMODfiNDEON (Greek, salt tree ; referring to 

 the maritime habit of the plant). Leguminbsce. A 

 genus whose sole representative is a hardy deciduous 

 shrub 4-10 ft. high, growing in the dry, barren salt- 

 fields of Siberia. It is characterized by the small, equally 

 pinnate lvs. ending in sharp, stinging spines, and com- 

 posed of 1-2 pairs of clean Ifts., and by the rather large 

 rose-purplish fls., in 2-3-fld. lateral fascicles from the 

 old nodes at the base of the summer shoots, appearing 

 from May-July. The branches are whitish and prickly, 

 with small petiolar spines. In cultivation the shrub 

 is very hardy, enduring both drought and cold, and, 

 while it thrives in sandy soils, it succeeds, also, in 

 saline or alkaline. The rosy fls. and the airiness of 

 the fine lvs. make it very ornamental. It is propagated 

 by seeds, layers and cuttings, or may be grafted upon 

 the common Laburnum, upon Cararjana arbfrescens, 

 or Colutea arborescens .
