740 HESPEROSCORDL'.M 



HESPEKOSCOKDUM. CoQSult Brodiaea. 

 HETEROCfiNTEON. See Heeria. 

 HETEEOMfiLES is included in Photinia. 



HETEROPAPPUS (Greek, (wo tiiids of pappus). Com- 

 pos iloe. This includes a plant that lovers of our native 

 Asters and Boltonias should not neglect. It is a hardy 

 herbaceous perennial plant that bears azure-blue aster- 

 like lis. in summer. The genus is closely related to As- 

 ter, having the habit of the Asters of the section Cali- 

 meris. The plant in the trade is known as Calimeris 

 Tatarica. Heteropappus is closely related to Boltonia 

 and is not far from Callistephus, which contains the 

 China Asters. The chief botanical distinction resides in 

 the pappus, which in the large group containing Callis- 

 tephus and Aster is composed of numerous bristles ar- 

 ranged in one or more series, while Boltonias and Het- 

 eropappus belong to a group in which the pappus is 

 anomalous. In Boltonia it is composed of very short, 

 somewhat chaffy bristles, with the addition usually of 

 2-4 awns not longer than the akene. In Heteropappus 

 the pappus of the rays is composed of very short, some- 

 what chaffy bristles, while in the disk-fls. it consists of 

 numerous slender bristles arranged in 1 or 2 series. 



Heteropappus is a genus of 2-4 species from .Japan 

 and China. Herbs, erect, branched above : Ivs. alter- 

 nate, entire or coarsely toothed: heads in loose irregu- 

 lar panicles or solitary at the tips of branches : rays 

 white or sky blue. See Calimeris. 



hispidus, Less. {Calimeris Tatarica, Lindl.). Stem 

 roughish: Ivs. linear, acute, pubescent: branches spread- 

 ing, usually unbranched and bearing 1 head : involucral 

 scales acuminate, hirsute, herbaceous, not white-mar- 

 gined, .lapan. Sandy places of Mongolia. 



HETEROPHEAGMA (Greek, a» odd kind of capsule}. 

 Bigiwni&cew. This includes a tropical tree that is very 

 rare in cultivation. It grows 30-50 ft. high, with 5-7 

 leaflets, which are 7-9 in. long and about 5 in. wide, and 

 swelling tubular 5-lobed fls. 2 in. wide and densely 

 woolly outside. The plant was once offered in this 

 country as Bignonia adenophylln, but Bignonia belongs 

 to a tribe in which the dehiscence of the capsule is sep- 

 tifragal or septicidal, while Heterophragma belongs to a 

 tribe in which the dehiscence is loculicidal. Hetero- 

 phragma is a genus of 3 species of trees from India and 

 Africa. Lvs. opposite, arge, pinnate : fls. rosy, yellow 

 or orange, glabrous or tomentose outside; calyx irregu- 

 lar, 3-5-lobed during anthesis: capsule long, cylindrical 

 or compressed, falcate or twisted, loculicidally 2-vaIved; 

 septum flat or 4-angular: seeds winged on both sides. 



adenoph^Uum, Seem. {Bignbnia adenophi/lla, Wa.\l.). 

 Leaflets broadly elliptic, pubescent when mature : fls. 

 brownish yellow, densely woolly : capsule cylindrical, 

 twisted, 1-3 ft. long, 1 in. wide, resembling a cork screw. 

 India. 



HETEEOSMtLAX (Greek, another kind of Smilax). 

 Lilii'trrir. This includes an ornamental climber with the 

 habit of Smilax. but the perianth is undivided (instead 

 of 6-parted, as in Smilax) and the mouth is minutely 

 dentate. It resembles Smilax in having dioecious fls., 

 borne in umbels and tendril-bearing stalks. The genus 

 contains 5 species of woody climbers from India, Ma- 

 laya, China and Japan : lvs. 3-5-nerved : fls. small or 

 very small. Latest monograph in Latin in DC. Mon. 

 Phan 1:41 (1878). 



Japdnica, Kunth. Lvs. with stalks about Kin. long, 

 blades about 4-5 in. long: staminate fls. unknown. Ja- 

 pan, where it is cult, for the roots, which are used in 

 medicine. 



HETEEOSPATHE (Greek, a different kindof spaihe). 

 Palmtlcecr. Also -written Heterospatha. A genus of only 

 1 species, native of the small island of Amboyna, the 

 Dutch headquarters in the East Indies. It is said by 

 Sander and Co. to be arare and highly ornamental palm, 

 with graceful, spreading habit and pinnatisect leaves, 

 the segments being long, slender and tapering. Its 

 nearest allies of garden value are Verschaffeltia and 

 Dypsis, in which the stigmas are basilar in fruit, while 



HEUCHERA 



Heterospatha belongs to a group in which the stigmas 

 are eccentric or lateral in fruit. Other important ge- 

 neric characters are the 6 stamens with versatile an- 

 thers and the 1-celled ovary. The plant is procurable 

 from importers and from S. Fla. 



elita, Scheff. Tall, unarmed: lvs. terminal, long-peti- 

 oled, equally pinnatisect; segments numerous, lanceo- 

 late, narrowed at both ends, acuminate, 1-nerved, mar- 

 gins thickened and recurved at the base ; rachis round on 

 the back, flat on the face; sheath short, fibrous, swelled 

 at the base: spathes 2, the lower 2-crested, the upper 

 much longer. A very worthy palm. 



HEtJCHERA (Johann Heinrich von Heucher, 1G77- 

 1747, professor of botany at Wittenberg). Saxifragdceie. 

 This includes H. sanguinea which probably ranks among 

 the half-dozen best plants with small, red flowers. It is 

 very desirable for the hardy border, where it blooms 

 from spring to late fall. It is also useful to florists for cut- 

 flowers and for forcing. All the Heucheras resemble 

 our dainty wild flower, the Bishop's Cap (Mitella) in 

 their habit, as they have a tuft of heart-shaped, 5-9- 

 lobed, crenate leaves, from which spring a dozen or so 

 slender scapes a foot or more high with small fls. borne 

 in panicles, giving a delicate and airy effect. 



Heuchera belongs to a group of genera including Mi- 

 tella and Tiarella, in which the ovary is 1-celled. In 

 Heuchera the petals are 5 or 0, and entire; in Mitella 5, 

 3-fld or pinnatifid; in Tiarella Sand entire. Heuchera 

 has 5 stamens ; Mitella 5 or 10 ; Tiarella 10. The cap- 

 sule of Heuchera is inferior, 2-beaked; in Mitella su- 

 perior, not beaked ; in Tiarella superior, compressed. 

 Heuchera has about 20 species, all North American and 

 ranging from Mexico to the arctic regions. 



The attractive and petal-like portion of B. sanguinea 

 is the calyx, the petals being small in all Heucheras 

 (often shorter than the calyx). The other species are 

 attractive by reason of their general habit, and particu- 

 larly the graceful, open panicle, ff. sanguinea came 

 into prominence about 1884 and is now, according to J. 

 B. Keller, one of the most popular of hardy perennials. 

 The others are procurable from the largest dealers in 

 native plants and from western collectors. They range 

 from 3 in. to .3 ft. high, averaging about 1'^ ft., and 

 bloom in s\immer, having greenish white or purplish 

 fls. J. B. Keller writes that almost any good garden soil 

 suits them, and that they are not particular as regards 

 exposure to sunlight (though an open situation is pref- 

 erable), and that they look well in borders, rockeries, 

 separate beds and elsewhere. Prop, by division or seed.

 scarcely exserted).

 Var. alba ( /7. dllia, Hort.) has pure white lis., and was 

 int. iilimit isod by Haage & Schmidt. Var. spWndens, 

 int. I.S'.IS I'V the s':iiiii' firm, has dark crimson fls. Var. 

 robiista, or grandiilora, Hort., according to J. B. Keller, 

 is an improvenii-iit on the type, the bells being larger 

 and the color brighter. Var. hjbrida ("Rosy Morn"), 

 Hort., according to D. M. Andrews, is "more robust 

 than the type, foliage deeper cut and the divisions more 

 pointed: fls. rosy pink." Andrews adds that var. tllba 

 comes true from seed.
