 HELICONIA (from Helicon, a mountain in Greece, 

 consecrated to the Muses). ORD. Scitaminece. A genus 

 allied to Musa, containing about twenty-five species, all 

 of which are natives of the tropical regions of the 

 Western hemisphere. They are ornamental, but rarely- 

 grown, stove herbaceous perennials, with inconspicuous 

 flowers, borne on short spathes, and handsome foliage. 

 Heliconias may be propagated from seed, but the best 

 method is by division of the root- stock when growth 

 commences in spring. Separate pieces may be inserted 

 in 5in. pots, and grown on rapidly in a moist stove tem- 

 perature, repotting into larger sizes as becomes requisite ; 

 or they may be planted out in the stove, if desired. A 

 rich, loamy, open soil is best, and plenty of water should 

 be applied during the growing season, withholding it when 

 the plants die down, in winter. Shade must be given in 

 summer, to prevent the sun injuring the foliage. 



H. aureo-striata (golden-striped).* I. deep green, with the 

 course of the parallel-curved veins from the costa to the margin 

 traced out by yellow lines ; elongate-ovate, cordate at the base. 

 Stems striated with green and yellow. 1881. A noble plant 

 (I. H. n. s. 464.)
