Griffinia continued. 



stove bulbous plants, all natives of Brazil. Upper seg- 

 ments of the perianth distinctly broader than the others, 

 and directed upwards ; two of the remaining three spread 

 out at right angles, and the third directed downwards. 

 Leaves broad, usually stalked, and peculiarly netted. 



FIG. 152. GRIFFINIA BLUMENAVIA 



Griffinias thrive in well-drained fibrous loain. After 

 growth is completed, water should be withheld for a 

 time, in order to thoroughly ripen the bulbs. All the 

 species, unless forced, flower in spring and summer.

GHJNDELIA (named in honour of David H. Grindel, 

 a German botanist, 1766-1836). SYN. Donia. OBD. 

 Composite. A genus containing about twenty species of 

 hardy or nearly hardy, biennial or perennial, shrubby or 

 herbaceous plants, natives of North America and extra- 

 tropical South America. Flower-heads yellow, solitary at 

 the ends of the branches, and from lin. to 2in. across. 

 Leaves alternate, sessile or semi-amplexicaul, often rigid, 

 dentate, or ciliato-serrate. Grindelias are of easy culture 

 in peat and loam. Propagated by seeds, sown in spring 

 or autumn, in a cool greenhouse or frame ; by cuttings ; 

 and by divisions. 



G. argnta (sharp). JL-hfads yellow. July and September. I., 

 lower ones spathulate ; upper ones linear-oblong, serrated, one- 

 nerved. Stem simple, h. 1ft. Mexico, 1822. Herbaceous, hardy. 

 (B. R. 781, under name of G. angustifolia.) 



G. glutinosa (glutinous).* fl.-heads yellow ; involucres viscid. 

 January to December. I. ovate-oblong, serrated, evergreen. 

 h. 2ft. Peru, 1803. Shrubby, nearly hardy. (B. R. 187.) 

 G. grandiflora (large-flowered).* fl.-heads deep yellow or orange, 

 which, prior to expansion, is covered with the glutinous balsamic 

 secretion occurring in some other species of this genus, large, 

 about 14in. across. Summer. 1., radical ones spathulate ; cauline 

 ones sessile, clasping, dentate. Stem branching near the top. 



A. 2ift. to 3ft. Texas, 1851. Hardy biennial. (B. M. 4628.) 



G. Innloides (Inula-like).* fl-heads yellow. June to Sep- 

 tember. I. sessile, oblong-lanceolate, acute, serrated at end, 

 not viscid, h. lift. Mexico, 1815. Shrubby. (B. M. 3737; 



B. B, 248.) 



G. speciosa (showy), fl.-heads yellow, nearly Sin. across, covered, 



to a considerable thickness, with a transparent glutinous varnish. 



h. 2ft. Patagonia, 1852. Shrubby, nearly hardy. (L. & P. F. G. 



iii. 290.) 

 G. squarrosa (squarrose). fl.-heads yellow ; scales of involucre 



filiform at end, revolute, squarrose. July to September. I. 



oblong, amplexicaul, serrated, h. 2ft. North America, 1811. 



Herbaceous, hardy perennial. (B. M. 1706, under name of Donia 



squarrosa.) 



GBJSELINIA (named in honour of Franc. Griselini, 

 an Italian botanist, who flourished in the middle of the 

 eighteenth century). OBD. Cornacece. A genus com- 

 prising eight species of trees or shrubs, natives of New 

 Zealand, Chili, and Brazil. Flowers dioecious, in terminal 

 panicles. Leaves alternate, often nnequilateral, oblong, 

 sub-quadrate or lanceolate, thick, coriaceous, entire, 

 spinose- dentate or angulate; ribs inconspicuous; veins 

 reticulated. Griselinias thrive in light rich loam, and are 

 propagated by cuttings, or by layers. The species de- 

 scribed below are probably the only ones yet in cultiva- 

 tion. 

 G. littoralis (shore-loving).* fl. as in 0. lucida. I. ovate or 



oblong, less oblique at the base, wedge-shaped or narrowed into 



the slender rather long petiole ; veins very obscure below, h. 30ft. 



New Zealand, 1872. 

 G. lucida (shining), fl. minute ; pedicels jointed, very short ; 



panicles axillary, often as long as the leaves, much branched, 



minutel 



dry) hairs. 



ly pubescent, with spreading golden (when 

 I. very obliquely ovate, obovate or oblong, quite entire, obtuse or 

 rounded at the tip, very unequal towards the base, one side much 

 narrower than the other ; veins very distinct on the under surface. 

 h. 10ft. to 12ft New Zealand. G. macrophylla does not appear 

 to be more than a large-leaved form of this.
