A. Fl. -clusters on long stalks. 



discolor, Hemsl. (Campylobbtrys discolor, Hook.)- 

 Fig 1071 About 6 in high, but lopping over the side 

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

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



1071. Honmannia discolor (X %). 

 A loose-growing sprig. 



entire, satiny green above and rich light purple to green 

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

 peduncles. Mex. B.M. 4530. Excellent little 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. A. 

 most beautiful plant. 



AA. Fl.-clusters crowded in the axils. 



Ghiesbreghtii, Hemsl. Half shrubby, 2-4 ft. tall, 

 nearly glabrous: stem acutely 4-angled : Ivs. usually 1 

 ft. or less long, oblong-lanceolate-acuminate, entire, 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 Ghiesbrechtii. I.H. 8:279, as a 

 Campylobotrys. A form with handsomely mottled Ivs. 

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



regalis, Hemsl. 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 a Higginsia. 



Higginsia Rmzli, Hort., is described as "a very beautiful 

 new tropical plant, with dark bronzy leaves, streaked and 

 marbled with white." Saul. L H B 



HOHENBERGIA (personal name). Bromeliacece. 

 Species commonly referred to JEchmea, but the latest 

 monographer (Mez : DC. Monogr. Phaner. 9) retains 17 

 species under this genus. The genus differs from 

 jEchmea in technical floral characters, the petals being 

 ligulate, fls. always sessile and small, etc. H. Legrelli- 

 ana, Baker, is by Mez referred to JEchmea (^E. Lagrel- 

 liana, Mez) and by Bentham & Hooker to Portea. It 

 has also been referred to Ortgiesia. It is a strong Bill- 

 bergia-like plant, with 7-12 strong, entire, brown-scaly 

 Ivs. and a simple dense spike of red fls. standing 4-7 ft. 

 high : floral bracts serrate. Uruguay. For H. ferru- 



HOLLYHOCK 



HOLBCELLIA (Frederick Louis Holboell, once Supt 

 Bot. Gard., Copenhagen). Berberidacea? . This genus 

 contains a fine shrubby climber, which is unfortunate! 1 

 inferior in hardiness to Akebia quinata, the latter beinj 

 one of the best of all hardy vines. Holboellia resemble; 

 Akebia in having digitate Ivs., edible, oblong, indehis 

 cent berries and an indefinite number of ovules. It dif 

 fers in having 6 sepals and 6 minute petals, whil< 

 Akebia has 3 sepals and no petals. Both genera hav( 

 free stamens, while those of Stauntonia are mona 

 delphous. Holboellia has only 1 species. Generic char 

 acters are: fls. purple or greenish, monoecious; sepah 

 6, petal-like; staminate fls. with rudimentary ovaries 

 pistillate fls. with 6 very small, sterile stamens. 



Any one who was surprised with the "discovery" of th< 

 strange purple fls. of Akebia will be interested in th( 

 fls. of Holbcellia. These are also purple or vary to green 

 ish white, and the staminate fls., which appear later, an 

 highly fragrant. The plant should be tried outdoors ir 

 the South where an evergreen quick-growing climbei 

 is desired, as it makes annual shoots 10 to 12 ft. long 

 and the foliage is distinct and beautiful. For the coo 

 greenhouse it is too rampant and produces too few fls 



latifolia, Wallich. Leaflets commonly 3 or 5, but verj 

 variable in form and number. Himalayas. B.R. 32:49

HOLCUS (Greek, to draw out ; an old fable crediting 

 this plant with the power of drawing thorns from the 

 flesh). Graminece. About 8 species of annual or peren 

 nial tufted grasses from Europe and Africa. The onlj 

 species cult, is a forage grass of" poor quality but ca 

 pable of growing well in dry soil. Its nearest allies OJ 

 garden value are Avena and 

 Deschampsia, from which it 

 liffers as follows: spikelets 

 falling off whole, and glumes 

 with no or minute awns. 

 Avena and Deschampsia have 

 the floral glumes decidedly 

 awned and the empty glumes 

 remain on the plant when the 

 florets fall. 



lanatus, Linn. MEADOW 

 SOFT GRASS. Perennial, 2-3 

 ft. high: Ivs. downy: panicle 

 greenish or tinged purple. 

 Eu. A variegated form is cult. 

 abroad for ornament.

 Hollyhock is an old garden 

 favorite, full of sentiment 

 and association with 

 a distant past, and 

 only the ravages of 

 a dire disease have 

 robbed it of the proud 

 position itheld among 

 garden flowers dur- 

 ing the middle of the 

 present century. A 

 plant of strong, vig- 

 orous growth, noble 

 aspect, and of the 

 most ornamental 

 character, it must 

 not be neglected or 

 ignored, for we can 

 ill dispense with its 

 stately beauty. Be- 

 fore the ravages of 

 disease there were in 

 existence large col- 

 lections of named va- 

 rieties, and the Holly- 

 hock was then one of
