variety with variegated Ivs. Var. Sldre plsno, Hort., is 

 shown in F.S. 18:1891, with a red spot on the middle of 

 each segment. Gn. 48, p. 401. R.H. 1897, p. 1^9. Var.

HEMICtCLIA (Greek, semi-cireiilcir: referring to 

 the scar or furrow on the seed). Euphorbiiiem. This 

 iueludes a spreading tree, attaining a height of 40 ft., 

 which is cult, in S. Calif, hy Fraucesehi, who values it 

 for its "beautiful holly like Ivs. and red fruits." The 

 genus has about 9 species, natives of India, Ceylon and 

 the Eastern Archipelago, with no near allies of garden 

 value. Trees or shrubs: Ivs. alternate, petioled, entire, 

 leathery when full grown: tis. dioecious; petals none; 

 sepals of stamiuate lis. 4-5, the inner often larger and 

 somewhat petal-like: fr. a globose or ovoid, indehiscent 

 drupe: seed by abortion, usually solitary. H. Austra- 

 lasica is told from the other 2 Australian species by its 

 very short filaments and glabrous ovary. 



Australisica, Muell. Arg. Lvs. broadly ovate to 

 ovate-oblong, ohtuse, lK-3 in. long, finely veined be- 

 low: fr. nearly % in. long, very smooth, red and succu-

HEMIONiTIS (Greek, mule; the plants erroneously 

 supposed to be sterile). Polypodlclcea . A genus of 

 tropical ferns, with copiously netted veins and naked 

 sori following the veins. Eight or 9 species occur in 

 the tropics of both hemispheres. The plants are dwarf, 

 and are grown in Wardian cases by a few fanciers in 

 the Old World. For culture, see F<-,"».s-.

HENDEESON, PETER (Plate X.), 1822-1890, market- 

 gardener, florist, seedsman and author, was born at 

 Pathhead, near Edinburgh, Scotland, in 1822, anddied in 

 Jersey City, Jan. 17, 1890. He was trained in Old World 

 methods of gardening, came to America in 1843, worked 

 under Geo. Thorburn and Robert Buist, and in 1847 be- 

 gan business in. Jersey City as a market-gardener, with a 

 capital of .$500, saved by 3 yeai-s' hard work. He contin- 

 ued to live there until his death. The publication 

 of "Gardening for Profit" in 1865 marks an era in 

 American horticulture. It was the first American book 

 devoted entirely to market-gardening, and it helped to 

 induce many persons to enter the business. By the time 



HEPATICA 729 



of his death about 150,000 copies of the book are said to 

 have been distributed. It was written in an aggiegate 

 of 100 hours, when the author was working IB hours a 

 day, largely at manual labor. At the noon intervals and 

 late at night he wrote this work lying on his back, with 

 a pillow under his head. The secret of its success, and 

 of the author's, was the invention of new methods 

 adapted to operations on a large scale. The second edi- 

 tion in 1874, and the third in 1887, are both thorough re- 

 visions. 



"Henderson's Practical Floriculture," 18G8, was an 

 epoch-making book in commercial floriculture. Up to 

 this time most works on flower-gardening had been 

 written for the amateur. This point of view is neces- 

 sarily the commoner one, and Henderson's contribution 

 to it was "Gardening for Pleasure,'- 1875. In the compi- 

 lation of "The Handbook of Plants," )88I, he was largely 

 aided by C. L. Allen, and in the second edition, 1890, by 

 W. J. Davidson. "Garden and Farm Topics" was issued 

 in 1884, and in the same year appeared "How the Farm 

 Pays," a stenographic report of conversations between 

 Wm. Crozier and l^eter Henderson. It is claimed that 

 nearly a quarter of a million copies of his various works 

 have been sold. His seed business was founded at New 

 York in 1865. Lately more than 200.000 copies of the 

 various catalogues have been distributed annually. 



Few men, if any, have done so much to simplify and 

 improve methods of handling plants for commercial 

 purposes. His greenhouses were an object lesson to 

 mauy visitors, his methods were widely copied, and his 

 business successes were the goal of ambitious market- 

 gardeners and florists, among whom he was for mauy 

 years the most commanding flgure. He was a frequent

 ziri'-i. :iii,l .luiiiii; his forty-two years of business life is 

 -ii].|H,.,,l t,. liiiw written or dictated at least 175,000 

 l.iiir^. j'wM tliir.ls of these letters were written with 

 his ou u bands, and he always replied promptly to in- 

 quiries about methods of cultivation. A self-made man, 

 simple and abstemious in his habits, he was a tireless 

 worker. He combined in a high degree the faculties of 

 growing plants and of business ability. His mastery of 

 details was complete. His books are exceptionally read- 

 able, his powerful personality appearing through every 

 page. The records of his personal experience are prac- 

 tical, ingenious and fertile in suggestion. An account 

 of his life is published in a memoir of 48 pages by his 

 sou, Alfred Henderson. w AT

HEPATICA (/ii 

 Hanunciddcetr'. Hepatica 

 3 species, natives of the 

 north temperate zone. 

 Stemless, low perennials: 

 lvs. 3-lobedand sometimes 

 toothed; appearing after 

 the flowers and remaining 

 green over winter: scapes 

 1-fld., with an involucre 

 of 3 small sessile lvs. sim- 

 ulating a calyx : sepals 

 petal-like, white, pink or 

 purple: akenes short- 

 beaked, pubescent. Fig. 

 1038. The plants prefer 

 shade, but do fairly well in 

 open places. They should 

 remain undisturbed from 

 year to year, in rich, well- 

 drained loam. Well suited 

 to the north or east slope 

 of a rockery. Plants kept 

 in pots in a coldframe un- 

 til midwinter will quickly 

 bloom at any time desired 

 if removed to a warm room 

 or greenhouse. Prop, by 

 division or seed.
