HARDENBERGIA 



HATIORA 



cult, are grown abroad under glass by those who are 

 skilled in managing Austrahan woody plants; they 

 prefer peaty and porous soil, as they are, like most 

 Austrahan plants, impatient of too much or stagnant 

 moisture. The species first mentioned is cult, outdoors 

 in Calif. These plants can be trained into bush form. 

 Prop, is by seeds or by greenwood cuttings of lateral 

 shoots under glass in spring. 



A. Lfts. solitary: pods flat, with dry pulp inside. 

 monophylla, Benth. (Kennedya monophylla, Vent. A'. 

 longiraccmosa, Lindl. K. cordata, Lindl. K. ovata, 

 Sims). Lfts. usually reduced to 1, ovate to narrowly 

 lanceolate, rounded or cordate at the base, obtuse, 

 reticulate, 2-3 in. or sometimes 4 in. long: fls. less than 

 3/^in. long, in 2's or rarely 3's, as many as 35 in a raceme, 

 and the upper racemes often forming a terminal 

 panicle. B. 2:84. B.M. 263, 2169. L.B.C. 8:758 and 

 20:1940. B.R. 944; 1336. R.H. 1896, p. 431. R.B. 

 22:169. — The fls. range from white through rose and 

 purplish to pure violet, but are never distinctly blue. 

 Var. alba and var. rosea are cult. 



AA. Lfts. 3 or 5: pod turgid, without pith or pulp. 

 Comptoniana, Benth. (Kennedya Comptoniana, Link. 

 A', nmcrophylla, Lindl.). Lfts. 3. or 5, and in the latter 

 case the lateral ones close together in 2 opposite pairs, 

 not opposite in distant pau's, oval to linear-lanceolate, 

 rounded or truncate at the base, obtuse, lJ^-2-3 in. long, 

 rarely longer: fls. similar to those of the preceding spe- 

 cies, but usually blue or violet-blue and in pairs or 

 clusters of 3-4 along the racemes. B.R. 298; 1862; 

 26:60. R.H. 1882, p. 344. J. H. TIL 30:361; 44:253. 

 P.M. 8:27, 267. H.U. 5:236. Var. alba is cult. 



H. Tetusa, Benth., is an anomalous species not cult. All other 

 names in this genus are synonyms of the 2 species described above.

HARDHACK: Spirxa tomentosa. 



HARDY PLANTS. The word "hardy" covers many 

 distinct ideas. It is used to distinguish plants that can 

 be cultivated outdoors the year round from plants that 

 must be grown under glass part or all of the year. For 

 example, in this Cyclopedia plants are spoken of as 

 hardy as far north as Washington, D. C, New York, 

 Boston or Montreal, meaning that the plants are not 

 killed by the winters at these places. In its widest 

 sense, "hardy" indicates resistance to all kinds of 

 unfavorable conditions. Thus, while all the common 

 geraniums are tender plants, one variety may be hardier 

 than another because it withstands intense heat and 

 drought and general neglect. In general, however, the 

 unquahfied word "hardy" indicates that the plant is 

 able to withstand the winter of the given place. See 

 the articles Border and Landscape Gardening. Smaller 

 divisions of the subject of hardy plants are discussed 

 under Alpine Plants and Aquatics. 



HAREBELL: Campanula rotundifolia. 



HARICOT (French name for Phaseolus vulgaris). 

 Same as kidney bean of the English. It is the common 

 garden bean of America, as distinguished from the 

 Windsor or broad bean, lima bean, and others. See Bean. 



HARiNA: WalUchia. 



HARIOTA: Halioni. 



HARLEQUIN FLOWERS: Sparazis. 



HARPALHIM: Hdianthus. 



HARPEPHfLLUM (from the Greek for stcfcie and 

 leaf, in reference to the falcate lfts.). Anacardiacese. 

 Kafir Plum. Two species, of which H. caSrum, 

 Bernh., is cult, in Fla. and S. CaHf. It is a tall, glabrous 

 tree with hard, heavy wood: Ivs. thick, lustrous, 

 imparipinnate, alternate, aggregate at top of branches, 

 stalked; lfts. sessile, falcate-lanceolate: fls. smaU, in 



compact axillary panicles, dioecious; calyx with 5 

 obovate segms.; petals 5, narrow-ovate, imbricate in 

 the bud; stamens 10 in the male fl., somewhat shorter 

 than the petals, inserted below margin of the disk: fr. 

 obovate, with thick woody endocarp, 4-celled, with 2 

 small, sterile cells, and 2 large fertile cells, dark red, 

 size and shape of a large oKve, the very thin pulp hav- 

 ing a subacid taste; edible. S. Afr. l H. B. 



HARRISIA (named for WilUam Harris, Superintend- 

 ent of PubUc Gardens and Plantations, Jamaica). Cac- 

 tacese. Upright tall cacti, little planted. 



Stems rather slender, sometimes weak: branches 

 fluted and having 8-11 rounded ribs: areoles bearing 

 slender needle-hke spines: fls. tubular, rather large, 

 growing from near the tips of the branches, night- 

 blooming: fr. naked, globose, yellow. — About 8 species 

 known; these confined to the W. Indies. 



gracilis, Brit. (C'crcus repdndus of Cyclo. of Amer. 

 Hort., not Cactus repdndus, Linn.). Sts. said to be 20 ft. 

 long: ribs 8-10: spines in clusters of 9-12: fls. white, 

 the bracts on the tube filled with long white hairs. 



J. N. Rose. 



HARTWEGIA (Theodor Hartweg collected in 

 Mex. for the Horticultural Society of London, and 

 found these plants near Vera Cruz). Orchidacese. 

 Tender epiphytic orchids from Trop. Amer., growing 

 about a foot high and bearing purple fls. The genus 

 has the habit of Epidendrum, section Amphiglottis, 

 but differs in having the labellum saccate at the base, 

 in which respect the genus approaches Ponera ; however, 

 Ponera has a very different habit. — Two species. 

 Rest them in a coolhouse Oct. to March. Growing 

 temperature should be 65-90°. 



purpurea, Lindl. Lvs. sohtary, leathery, ovate-lanceo- 

 late, equally terete with the st., many times shorter 

 than the thread-like peduncle: fls. small, purple; sepals 

 acute, a little larger than the petals; limb of the lip 

 white at the base, callous. Mex. 



H. gemma, Reichb. f. "This is a most lovely gem," wrot« 

 Reichenbach, and "much better than its predecessor." Gemma, 

 therefore, probably does not mean "twin," in this case. Lvs. 

 solitary, semi-terete, thick, acute, channelled, blotched with 

 blackish violet: fls. amethyst-purple, in a small, 1-branched panicle; 

 odd sepal acute, obtusely strap-shaped, equal sepals oblong-acute. 



Cent. Amer.

HASTINGSIA (S. Chnton Hastings, San Francisco, 

 promoter of Calif ornian botany). Lilidcese. Two bul- 

 bous plants of the Pacific slope, separated by Sereno 

 Watson from the genus Schoenolirion (the Oxytria of 

 Rafinesque), offered by collectors but little known in 

 cultivation. 



Plants with white or^greenish fls. in many-fld. dense 

 panicles or racemes: perianth-segms. distinct, each 

 obscurely 3-nerved; stamens 6; style short; ovary 

 oblong-ovate and not deeply lobed (so differing, among 

 other things, from Schoenolirion, which has a depressed- 

 globose deeply 3-lobed ovary and fr.). Hastingsias 

 have strong, nearly naked sts., arising from a tunicated 

 bulb: lvs. lather fleshy. Treatment as for camassia. 



alba, Wats. Mostly stout, 2-3 ft. high: lvs. IJi in. 

 or less wide: racemes simple or nearly so, 1 ft. long, 

 densely fld., the fls. J-^in. or less long, white or greenish 

 white; stamens equaling the segms. Dry hillsides, N. 

 Calif, northward. 



bracteosa, Wats. Bracts naiTow and nearly equahng 

 the fls., which are larger than in the other, and white; 

 stamens half as long as segms. : lvs. narrower. S. Ore., 

 in marshes. L, jj, b_ 



HATIORA (an anagram of Hariota). Cactacese. 

 Upright cacti, allied to Rhipsalis. 



Plants erect, branching: branches short, arising 

 in 2's or 3's from tops of older branches, smooth ;md 

 spineless, bearing several abortive areoles along their 

 sides and each a large wooUy terminal one from which
