HOFFMANNIA 



HOLCUS 



A. Fl.-clusters on long stalks. 



discolor, Hemsl. (Campylobolrys discolor, Hook.). 

 Fig. 1S43. About 6 in. high, but lopping over the side 

 of the pot or pan and making a mat, shghtly hairy, the 

 branches purphsh: Ivs. short-petioled, oblong-obovate, 

 entire, satiny green above and rich Ught purple to green 

 beneath: fis. small, red, in recurving racemes, on red 

 peduncles. Mex. B.M. 4.530.— Excellent httle plant. 



refulgens, Hemsl. Much like the former, but twice or 

 more as large, the Ivs. sessile and almost succulent, nar- 

 row-obovate, with many parallel veins running from the 

 midrib to the margin, the under-surface pale red or 

 wine-color and the upper surface dull green, with iri- 

 descent shades of purple and brown: fls. 1 in. across, 

 pale red. Mex. B.M. 5346 (as Higginsia refulgens). 

 H.F. II. 5:78.— A most beautiful plant. 



A.^. Fl.-clusters crowded in the axils. 

 Ghiesbreghtii, Hemsl. (CampylSbotrys Ghicshreghtii, 

 Lem.). Half-shrubbj', 2-4 ft. tall, nearly glabrous: st. 

 acutely 4-angled : Ivs. usually 1 ft. or less long, oblong- 

 lanceolate-acuminate, entu'e, the short winged petiole 

 somewhat decurrent, very strongly veined, purple-red 

 beneath and dark velvety green above: fls. yellow, with 

 a red spot in the center. Mex. B.M. 5383 (as Higginsia 

 Ghiesbrcchtii) . I.H. 8:279 (as Carapylobotrys). G.W. 

 15, p. 330. — A form with handsomely mottled Ivs. is 

 var. variegata, Hort. (I.H. 30:498). 



regalis, Hemsl. (Campylobotrys regalis, Lind.). 

 Shrubby, strong-growing, glabrous, the branches 

 obtusely 4-angled and somewhat fleshy: Ivs. large, 

 round-ovate and abruptly acuminate, entire, plicate 

 with arched nerves, glabrous, purple-red beneath and 

 dark rich green above: fls. yellow, sessile. Mex. B.M. 

 5280 (as Higginsia). 



H. j>h(rnic6poda, K. .Schum. Lvs. ovate to oblong, \'iolet-red 

 beneath: fls. inconspicuous. Cent. Amer. T TT R 



HOFFMANSEGGU (Joh. Centurius, Count von 

 Hoffmansegg, born 1766; WTOte on plants of Portugal). 

 Leguminosse. Thirty and more dwarf mostly glandular 

 herbs and subshrubs from Kans. and Calif, to Pata- 

 gonia, and in S. Afr., perhaps not cult.: Ivs. bipinnate, 

 with or without black glands: fls. yellow in naked 

 racemes opposite the lvs. or terminal; petals 10 and 

 nearly equal; stamens 10 and distinct: pod fiat, oblong, 

 sometimes falcate. The genus is allied to Cassia, from 

 which it differs in its bipinnate rather than pinnate lvs., 

 and to Cjesalpinia, which is distinguished by its prick- 

 les, woody stature, and other characteristics. 



HOHENBERGIA (personal name). Bromeliacex. 

 Interesting hothouse subjects grown in pots, closely 

 allied to jEchmea. 



Leaves forming a dense rosette, spiny-margined, 

 often terminated with a stout spine: panicle on a taU 

 scape, bi- or tripinnate, of short, dense, sessile or 

 stipitate spikes; fls. sessile in the axils of large bracts, 

 white or blue. — A Trop. American genus of about 20 

 species. 



augusta, Mez (.Echmea augusta, Baker. Hoplo- 

 ■phytum augustum, Beer). Lvs. up to 3 ft. long and 3 

 in. broad, spiny, with pale scales on both sides: panicle 

 pyramidal, much exceeding the lvs., floccose; fls. a 

 Lttle less than J-jin. long, the petals blue. Brazil. 



stellata, Schult. UEchmha glomerata, Hook.). Lvs. 

 up to 3 ft. long, and 3 in. wide, marginal spines long: 

 panicle interrupted, equaling or little exceeding the 

 lvs. ; fls. about 1 in. long, the petals blue. Trinidad and 

 Brazil. B.M. 5668. 



Legrelliana, Baker (Mchniha Legrelliana, Mez. Guz- 

 mania Legrelliana, Hort.). A strong billbergia-Uke 

 plant, with 7-12 strong, entire, brown-scaly lvs. and a 

 simple dense spike of red fls. standing 4-7 ft. high: 

 floral bracts serrate. Uruguay. George V. Nash. 



HOHERIA (from the New Zeal, vernacular name 

 hoheri). Malvacese. Small trees or shrubs native to 

 New Zeal.: lvs. variable, alternate, serrate, petiolate: 

 fls. numerous, white, in axiUary fascicles; peduncles 

 jointed at the middle; bracteoles wanting; calyx hemi- 

 spherical, 5-toothed; petals oblique, notched near the 

 apex; staminal column split at the top into numerous 

 fllaments, usually arranged in 5 bundles: fruiting car- 

 pels 5, indehiscent, furnished with a broad membranous 

 wing at the back. — Three or 4 species; by some regarded 

 as one variable species. H. populnea, A. Cunn. A 

 small, handsome tree, 10-30 ft., glabrous except the 

 young shoots, peduncles and calyxes, which are more 

 or less pubescent: lvs. very variable, especiaUy in young 

 plants: fls. snow-white, produced in great profusion: 

 carpels produced outward and upward into a mem- 

 branous wing, longer than broad. G.C. III. 30:384; 

 52:355. On. 62, p. 309; 76, p. 580. Scarcely cult. 



HOIBRENKIA: Staphylea. 



HOLBOELLIA (Frederick Louis Holboell, once 

 Superintendent of Botanical Garden, Copenhagen). 

 Lardizabalacese. Ornamental vines grown chiefly for 

 their handsome evergreen digitate foliage. 



Twining shrubs: lvs. coriaceous, long-petioled, 

 digitate, with 3-9 stalked entire Ifts.: fls. mona'cious, 

 in few-fld. racemes; sepals 6, petal-like, obtusish, fleshy; 

 between the sepals and the 6 free stamens 6 smaU 

 nectaries sometimes called petals; the staminate fls. 

 with rudimentary ovaries; the pistillate with small 

 stamens and 3 distinct carpels developing into 1-3 

 large oblong pods with numerous black seeds. — Five 

 species in China and Himalayas. 



The holboeUias are quick-growing evergreen vines 

 very similar in foliage to Akebia quinata but the flowers 

 are quite different; they are either white or the pis- 

 tiUate are purplish and the staminate which are borne 

 in separate racemes whitish or greenish white; they 

 appear with the young leaves in spring and are not 

 showy, but the large purple pods are conspicuous. 

 None of the species is hardy North, but the plants 

 should be tried outdoors in the South where an ever- 

 green quick-growing climber is desired, as they make 

 annual shoots 10 to 12 feet long, and the foliage is 

 distinct and beautiful. For the cool greenhouse they 

 are too rampant and produce too few flowers. Propa- 

 gation is by seeds which germinate readily; also by 

 layers and by softwood cuttings. For further cultural 

 notes, see Slauntonia. 



coriacea, Diels. Lfts. always 3, coriaceous, ovate to 

 oblong-lanceolate or narrow-oblong, acute, rounded 

 or broadly cuneate at the base, light green below with 

 the veinlets not visible, 2-3J4 in. long: fls. 3-^-3^in. 

 long; the staminate whitish, on pedicels about 1 in. 

 long, the pistiUate purphsh on pedicels to 2 in. long. 

 Cent. China. 



latifolia, Wall. Lfts. 3-7, ovate-oblong to eUiptic- 

 oblong, acuminate, pale green below and reticulate, 

 2J^-3}-2 in. long: fls. about l-im. long, in short-pedun- 

 cled racemes, on pedicels M-J^in. long; the pistillate 

 purple, the staminate greenish white, fragrant: fr. 

 consisting usually of 2 oblong carpels, each about 4 

 in. long and 2 in. thick, rosy purple, edible. Himalayas.

 548; 14, p. .369. 



H. cuneata, 01iver=Sargentodoxa cuneata. — H. Fdrgesii, Rfiau- 

 bourg. Lfts. 5-9. usually oblong-lanceolate, glaucescent below: fls. 

 ^4in. long, purplish and greenish white. Cent. China. — H. grandi- 

 fldra, R^aubourg. Lfts. 5-7, usually lanceolate, reticulate and 

 grayish green below: fls. nearly 1 in. long, waxy white. W. China.

HOLCUS (Latin name for a kind of grass, from holkds, 

 attractive). Gramines\ This genus, named Holcus 

 by Linnaeus, was called Sorgum by Adanson (Sorglmtn, 

 Moench). The name Holcus was accepted by some 

 botanists while by others the genus was united with
