PLANT MATERIAL INTRODUCED 



78856 to 78870. 



From Stevenage, Herts, England. Seeds 

 purchased from Clarence Elliott (Ltd.), 

 Six Hills Nursery. Received February 2. r >, 

 1021). 



78856. AGAPANTHUS AFEICANUS (L.) 



Hoffmannsegg (Abumon africanum 

 Britton). Liliaceae. African lily. 



Variety Mooreanua. A robust tuber_ 

 ous-rooted plant reputed to be winter- 

 hardy, 1% feet high, with short straplikc 

 leaves and dark-blue flowers in fair-sized 

 umbels. 



78857 to 78862. Gentiana spp. Gentiana- 

 ceae. Gentian. 



78857. Gentiana gentianella A. T. 

 Johnson. Stemless gentian. 



A stemless European alpine plant 

 which forms a dense carpet of com- 

 pact tufts of glossy green leaves from 

 which rise large tubular flowers of an 

 amazingly deep blue. 



78858. Gentiana asclepiadea L. 



Milkweed gentian. 



A comparatively robust subalpine 

 species forming clumps of vigorous 

 stems up to 3 feet high with opposite 

 ovate leaves. In late summer it pro- 

 duces from the uper axils almost sessile 

 trumpet-shaped flowers of sapphire blue 

 which weigh down the arching stalks. 

 There is some variation in color from 

 seed, which germinates freely and pro- 

 duces flowering plants in about three 

 years. The plant is said to be indif- 

 ferent as to whether the soil is alkaline 

 or not. 



78859. Gentiana bavarica L. 



A difficult species requiring condi- 

 tions similar to those of moist alpine 

 meadows for success. It forms com- 

 pact tufts of stout stems about 3 

 inches high with yellpw-green boxlike 

 leaves and flowers somewhat like those 

 of Gentiana verna, with five large 

 lobes, but of a velvety dark-blue color 

 and produced much later in the sum- 

 mer. It is said to be indifferent to 

 limestone or granite soils provided it 

 has the proper moist turfy soil. 



78860. Gentiana lagodechiana Hort. 



A dwarf form of Gentiana septem- 

 fida, with deeper blue flowers and 

 prostrate habit. 



78861. Gentiana septempida Pall. 



An Asiatic gentian which somewhat 

 resembles Gentiana asclepiadea, re- 

 quiring similar conditions. It makes 

 spreading clumps up to 12 inches high 

 with opposite ovate leaves and heads 

 of wide-mouthed trumpet-shaped blue 

 flowers in late summer. It varies 

 considerably in habit and flower color, 

 but all forms do well in peaty loam 

 with ample but not stagnant water 

 supply. 



78862. Gentiana verna L. 



This is the gentian of the Alps, diffi- 

 cult in cultivation unless provided with 

 peaty soil filled with sharp sand, a 

 liberal supply of coarse broken stone, 

 perfect underdrainage, and a constant 

 supply of moisture in summer. It is 

 a social plant and should be grown 

 with other plants to simulate an alpine 

 turf, where it will produce vigorous 

 clumps of low shoots, gray-green foli- 

 age, and, in early summer, myriads of 

 starry flowers of ' indescribable blue. 



78856 to 78870— Continued. 



• 78863. Iius sintenisii Janka. Iridaceae. 



A beardless iris of the same general 

 type as Iris fjraminea with tufted ever- 

 green leaves about 12 inches high and 

 flower stalks little higher than the 

 leaves. Flowers blue purple as in I. 

 grammea with red purple on the style 

 branches and hafts. Native to southeast- 

 ern Europe and Asia Minor. 



78864. Lilium rdbellum Baker. Lilia- 

 ceae. Rubellum lily. 



A miniature trumpet lily from Japan 

 with slender green stems spotted with 

 purple, rarely exceeding 2 feet in height, 

 narrow leaves, and one to eight smallish 

 trumpets of rosy white, flushed darker 

 without. It is more delicate than 

 Kramer's lily {Lilium japonicum), and, 

 like it. should be grown in a low shrubby 

 undergrowth, where its head can rise to 

 full sun. 



78865 to 78868. Primula spp. Primula- 

 ceae. Primrose. 



78865. Primula sp. 



Primrose blue. A blue-flowered hor- 

 ticultural strain of the common garden 

 primrose. 



78866. Primula helodoxa Balf. 



A large Chinese primrose, with 

 flower stalks like those of Primula 

 japonica, about 3 feet high, with seven 

 or eight tiers of soft-yellow flowers re- 

 sembling in color and size those of 

 Jasminum primulinum. It requires a 

 moist but well-drained site. 



78867. Primula polyantha Mill. 



Polyanthus primrose. 



A European primrose, about a foot 

 high, with more or less upright yellow 

 flowers in erect umbels which stand 

 above the long leaves. 



78868. Primula sikkimensis Hook. 



This primrose, with flower stalks 1 

 or 2 feet high and with the habit of 

 Primula secundiflora, grows in moist 

 meadows and along stream beds in the 

 Himalayas at an altitude of 13,000 

 feet. The lanceolate drooping leaves 

 are dull green on both sides, and the 

 rich-yellow flowers, which appear in 

 June, are large and bell-shaped. It 

 should be treated as a short-lived 

 perennial. 



78869. Sisyrinchium boreale (Bickn.) 

 J. K. Henry. Iridaceae. 



A semiaquatic plant uo to a foot in 

 height, with narrow leaves and yellow 

 flowers on erect pedicels. Native to 

 southwestern Canada and northwestern 

 United States. 



78870. Sisyrinchium filifolium Gaud. 

 Iridaceae. 



A herbaceous perennial, 6 inches to a 

 foot in height, native to the Falkland 

 Islands. In cool peaty soil, with good 

 drainage, it spreads into grassy tufts of 

 narrow rnshlike leaves, and produces from 

 six to nine stalks with white bell-shaped 

 flowers of exquisite delicacy.

 from T. Smith, Daisy Hill Nursery. Re- 

 ceived February 23. i929.
