HETERANTHERA 



HETEROSPATHE 



oblong, obtuse. H. renifdrmis, R. &. P., has smaller 

 white or pale blue fls. : spathe 3-5-fld.: Ivs. orbicular- 

 reniform to cordate, acute. Both these species have 

 unequal anthers. H. dubia, MacM., has equal anthers 

 and small pale yellow fls. All these are natives in E. 

 U. S. and southward, and are useful- for transferring 

 to wet grounds and shallow pools. L jj g 



HETEROCENTRON (unlike spurs, referring to 

 structure of anthers). Melastomacese. Includes Heeria 

 of Schlechtendal, not of Meissner. About 6 Mexican 

 and Central American species, sometimes grown under 

 glass. 



Herbs or shrubs, erect or prostrate, with opposite 

 membranaceous pinnately nerved (rarely 3-nerved) 

 entire Ivs., and white, rose or purple irregular fls. in 

 panicles or rarely solitary: stamens 8, very unequal, the 

 4 larger ones with long appendages or connections; 

 ovary loculed; petals 4. Not to be confounded with 

 Centradenia, which has winged sts. unequal-sided 

 Ivs., and calyx-teeth small and much shorter than 

 the calyx-tube. Warmhouse plants, requiring the 

 cult, of centradenia, but grown chiefly for the fls., 

 whereas centradenias are grown also for foliage. 



roseum, A. Br. (H. mexicdnum, Naudin. Heeria 

 rosea, Triana) is the only species in general cult.: 1 

 ft. or more high, with 4-angled (but not winged) St.: 

 Ivs. elliptic, obtuse or acute, pinnate-nerved : fls. bright 

 rose, in a large, terminal panicle, showy, in autumn and 

 early winter. B.M. 5166. I.H. 3:97. Var. dlba, Hook., 

 is a white-fld. form. 



subtriplinervium, A. Br. (Heeria subtriplinervia, 

 Triana). Little branched, the branches sharply 4- 

 angled, the young foliage and calyx sparsely pilose: Ivs. 

 oblong-lanceolate, acute at apex, narrowed into long 

 petiole, the margin entire, blade 9-13-nerved: fls. 

 white, the petals broadly obovate with retuse apex. 

 Mex. 



H. elegans, O. Kuntze (Heeria elegans, Schlecht. H. procum- 

 bens, Naudin), will be found under Sehizooentron. L H B 



HETER6MELES: Photinia. 



HETEROPAPPUS (Greek, two kinds of pappus). 

 Composite. A hardy herbaceous perennial that bears 

 azure-blue aster-like flowers in summer. 



Herbs, erect, branched above: lys. alternate, entire 

 or coarsely toothed: heads in loose irregular panicles or 

 solitary at the tips of branches, rays white or sky- 

 blue. The genus is closely related to Aster, having the 

 habit of the asters of the section Calimeris. The plant 

 in the trade is known as Calimeris tatarica. Hetero- 

 pappus 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 Callistephus and 

 Aster is composed of numerous bristles arranged in 

 one or more series, while Boltonia and Heteropappus 

 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 achene. 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. A 

 genus of 2-4 species from Japan and China. 



hispidus, Less. (Calimeris tatarica, Lindl. Aster 

 hispidus, Thunb.). St. roughish: Ivs. linear, acute, 

 pubescent and ciliated on the margins : branches spread- 

 ing, usually unbranched and bearing 1 head: inyolucral 

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

 gined, rays blue. Japan, Mongolia. L. jj. B. 



HETEROPHRAGMA (Greek, different and septum; 

 alluding to the peculiar 4-angled septum of the typical 

 species). Bignonidcese. Three species of E. Indian 

 trees, with large opposite pinnate Ivs. and large yellow 



or pink fls. in terminal panicles or from the old wood: 

 calyx campanulate, irregularly 3-5-lobed; corolla cam- 

 panulate-funnelform; ovules in several series in each 

 cell of the broadly linear ovary: caps, cylindric or 

 compressed, falcate or twisted, loculicidally 2-valved; 

 septum flat or 4-angled. The 2 African species referred 

 by some writers to this genus belong to Fernandia. 

 Only the following species has been offered in this 

 country. H. adenophyllum, Seem. (Bignonia aden- 

 ophylla, Wall.). Tree, 30-^50 ft.: young growth tomen- 

 tose: Ifts. 5-7, broadly elliptic, acute or obtuse, entire, 

 tomentose, 7-9 in. long: fls. in terminal panicles; calyx 

 irregularly 5-lobed; corolla brownish yellow, densely 

 woolly outside, with spreading 5-lobed limb, 2 in. wide : 

 caps, twisted, resembling a cork-screw, 1-3 ft. long; 

 septum flat. Wight, 111. 160 (as Spathodea adenophylla). 

 Little known in cult, and adapted for subtropical or 

 tropical countries only. Prop, probably like Rader- 

 machia by cuttings and air-layering. 



ALFRED REHDER. 



HETEROPTERIS (various winged, referring to the 

 fr.). Malpighidcese. Shrubs, erect or rarely climbing, 

 of Trop. Amer. and 1 in W. Afr. Fls. small, yellow or 

 purple, in panicles or racemes: Ivs. opposite, nearly or 

 quite entire. The calyx is 5-parted, some or all the 

 lobes with a pair of sessile glands; petals clawed; sta- 

 mens 10, all perfect but unequal; ovary 3-celled, with 

 3 subulate styles, the stigma on an angle of the style: 

 fr. 1-3 samaras, with a somewhat semi-circular wing. 

 Species 90 or more. The climbing species may be found 

 in choice collections. H. purpiirea, Kunth, is a low 

 cumber among shrubs, according to Grisebach, in the 

 farther W. Indies and Venezuela: Ivs. oval, glabrous, 

 somewhat glaucous beneath, the petiole with 2 glands 

 at the middle: fls. purple, corymbose or racemose, on 

 slender pedicels that are jointed below the middle: fr. 

 1 in. long, with semi-obovate oblique wings. H. chry- 

 sophylla, HBK. Twining: Ivs. oval or oval-oblong, 

 entire, glabrous above and golden pubescent beneath: 

 fls. orange, becoming reddish. Brazil. B.M. 3237. 

 An interesting plant for the warmhouse, long-climbing.

HETEROSMILAX (Greek, another kind of Smilax). 

 Lilidcese. 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 

 2-5-dentate. It resembles smilax in having dioecious 

 fls. borne in umbels, and tendril-bearing petioles. The 

 genus contains 5 species of woody climbers from India, 

 Malaya, China and Japan: Ivs. 3-5-nerved: fls. small 

 or very small. Little known culturally outside the 

 far East. 



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

 blades about 4-5 in. long. Japan, where it is cult, for 

 the roots, which are used in medicine; Hemsley writes 

 that it is said to have been intro. into Japan from China 

 but that no Chinese specimens are known to exist 

 (1903). L. H. B. 



HETEROSPATHE (Greek, a different kind of spathe). 

 Also written Heterospatha. Palmdcese, tribe Arecese. 

 A rare 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 basal in fr., while 

 Heterospatha belongs to a group in which the stigmas 

 are eccentric or lateral in fr. Other important generic 

 characters are the 6 stamens with versatile anthers 

 and the 1-celled ovary. Only 1 species, native of the 

 small island of Amboyna, the Dutch headquarters in 

 the E. Indies. Intro, from the Java botanic garden in 

 1879 to England. The plant is procurable from import- 

 ers and from S. Fla., but is cult, in Amer. only in 

 botanic gardens.
