HOFFMANNIA (named after G. F. Hoffmann, 1761- 

 1826, Professor of Botany at Gottingen, &c.). Including 

 Campy iobotrys. STNS. Higginsia, Ohigginsia. OBD. 

 Rubiacece. A genus comprising about twenty species of 

 herbs or shrubs, natives of tropical America. Flowers 

 white, yellow, or red, small, in axillary, few - flowered, 

 occasionally unilateral, pedunculate or sub-sessile cymes. 

 Leaves opposite, or two to four-nate, verticillate ; stipules 

 interpetiolar, small, broadly triangular or transversely 

 oblong - linear, deciduous. Hoffmannias will thrive in 

 the open air in summer, if planted in sandy soil ; but 

 they require the protection of a greenhouse in winter. 

 Propagated by cuttings, inserted in sandy soil, under 

 a bell glass, in bottom heat. 



Hoffmannia continued. 



H. pedunculate (pedunculate). fl., corolla yellow, and varie- 

 gated with red, rotate ; racemes few to eight-flowered, peduncled- 

 peduncles as long as, or exceeding, the petiole. I. elliptical,' 

 pointed, cuneate at the long-petioled base, glabrescent above, 

 rusty-pilose, with scattered down beneath, h. 2ft. to 3ft. Jamaica 

 (in mountain woods). 



H.refulgens (shining).* fl. pale red, upwards of lin. across, in 

 solitary cymes ; corolla lobes much longer than the tube 

 peduncles solitary, axillary, erect, purple-red, shorter than the 

 leaves. May. 1. 3m. to oin. long, narrow-obovate, sub-acute 

 contracted at base, but not petioled ; upper surface dull green 

 suffused with red, especially towards the margins ; under surface 

 pale reddish. Branches purple, erect, h. 1ft. to 2ft. South 

 America. (B. M. 5346, under name of Higginsia refulgens.) 



H. regalis (royal), fl. aggregate, sub-sessile, unattractive. 

 August. J. roundly-ovate, acuminate, entire, sub-coriaceous, 

 plicato-penninerved, glabrous, shining dark green 



, 



above, reddish-purple beneath ; stipules triangular, 

 deciduous. Branches sub-succulent, obtuse, tetra- 

 gonal. h. 1ft. Mexico, 1859. A robust stove 

 shrub. (B. M. 5280, under name of Higginsia 



See Spoudias and 



regalis.)

HOLBCBLLIA (named after Fred. Louis 

 Holboll, once Superintendent of thcj Botanic 

 Garden at Copenhagen). OBD. Berberidece. 

 A genus of only two species. H. latifolia 

 is an interesting cool greenhouse evergreen 

 climbing shrub. It is of easy culture in any 

 light soil. Propagation is effected by cuttings, 

 made of half-ripened shoots, in spring.

H. discolor (two-coloured).* This species " is remarkable for the 

 lurid-green yet satiny surface or velvety gloss of the upper side 

 of the leaves, and the rich red-purple tints of the branches and 

 under side of the foliage, and the still more pronounced red 

 colour of the peduncles and flowers and teeth of the calyx "(Sir 

 W. J. Hooker), h. 6in. Mexico, 1850. Stove. (B. M. 4530, 

 under name of Campylobotrys discolor.) 



H. Ghiesbreghtii (Ghiesbreght's).* fl. yellow, spotted red 

 on the disk, inconspicuous ; cymes on short axillary peduncles. 

 1. large, 1ft. or more long, broad oblong-lanceolate, acumi- 

 nate, entire, much decurrent and attenuated at the base, so 

 as to be perfoliate, strongly penninerved and sub-plicate ; upper 

 surface rich dark velvety -green above, very slightly pubescent ; 

 under surface dull purple-red, veins very prominent. Branches 

 green, herbaceous, elongated, h. 2ft. to 4ft. South America, 

 1861. (B. M. 5383, under name of Hiprjinsia Gheisbeehtii.) varie- 

 gata is a form with leaves blotched with creamy-white, yellow, 

 and red.

 Soft Grass. OBD. Graminece. A genus of eight species 

 of annual or perennial grasses, natives of Europe, tem- 

 perate Asia, North and South Africa. Panicles loose; 

 spikelets compressed, two-flowered. The species are of 

 easy culture in ordinary soil. The only one worth grow- 

 ing is the following: 

 H. lanatus albo - variegatus (woolly, white - variegated). I.
