" A dwarf evergreen shrub, 4 to 6 inches high, forming dense tufts, and 

 spreading by underground shoots ; stems slender and wiry, covered with 

 bristles, and bearing over their whole length leaves one-quarter inch 

 apart in two opposite rows. Leaves leathery, heart shaped, becoming 

 smaller toward the tip of the shoot ; one-quarter to five-eighths inch long, 

 about the same wide ; the lower surface and the margins are bristly, the 

 upper side is dark, dull green and wrinkled, the lower one very pale pol- 

 ished green ; stalk one-eighth inch or less long. Flowers produced singly 

 in the leaf axils from the under side during August ; corolla egg shaped, 

 white or tinged with pink, scarcely one-quarter inch long. 



" Native of the Himalayas ; long cultivated, but still rare in gardens. 

 It makes charming dense tufts of foliage and stems, but needs some 

 shelter. At Kew it thrives well in a damp bed of peat in one of the 

 recesses of the rock garden, where it has not suffered from cold since 

 the frosts of February, 1895. Its roundish leaves, closely and regularly 

 set in two rows, and gradually decreasing in size toward the end of the 

 shoot, with the slender, conspicuously bristly stems, render it quite 

 distinct from any other plant in cultivation. Increased by cuttings."

39016. Gentiana tubiflora Wallich. Gentianaceae. Gentian. 

 Distribution. — A very low, tufted herb with large blue flowers, found 



in the alpine Himalayas and in Tibet. 



39017. Gerbera kunzeana A. Br. and Asch. 



39018. Gynura angulosa DC. Asteraeere. 



Distribution. — An herbaceous composite, sometimes 10 feet tall, with 

 small flower heads and oblong leaves often 2 feet long, found on the 

 temperate slopes of the Himalayas up to an altitude of 4,000 feet, and in 

 the Khasi Hills, in India. 



39019. Iris cxarkei Baker. Iridacea?. Iris. 

 " Iris clarkei is obviously a member of the sibirica group, but differs 



from all the other species of that group, except /. prismatica, in the pos- 

 session of a solid, as opposed to a hollow, stem. In all other respects 

 it seems perhaps most closely related to the western Chinese members 

 of the group, J. forrestii and /. bullcyana, with which it agrees in having 

 leaves which are glaucous on the under side but polished and glossy 

 above. The color of the flowers borne by this Iris varies greatly even in 

 the wild state, as was proved by a second series of plants that I owe to 

 the kindness of Mr. Cave. All shades of blue and purple may occur. In 

 its native habitat, I. clarkei grows in ground that is swampy for half the 

 year and frozen hard under snow during most of the remaining months. 

 In cultivation it should naturally do best in damp soil, rich in humus, but 

 for some reason or other it has proved difficult to keep, for many plants 

 have died out after flowering. Seedlings are fairly easily raised, though 

 the seeds do not germinate very readily and the plants are of somewhat 

 slow growth. 



"Apparently confined to a circumscribed area in the Sikklm and 

 Bhutan region at a height of 6,000 to 11,000 feet." (Abridged from 

 Dykes, The Genus Iris, p. 29-30.)
