Cult. Phlox is a genus of elegant border flowers ; the most 

 of them thrive in common garden earth, but prefer a rich loamy 

 soil. Those species belonging to the third section of the genus, 

 being tender, more dwarf kinds, will require to be protected 

 under frames in winter, if severe ; and it is therefore safest to 

 have a plant or two of all these dwarfer kinds in pots. The 

 larger kinds are easily increased by dividing at the root ; and 

 cuttings of the dwarf kinds strike root freely if planted under a 

 hand-glass. 



IV. HU'GELIA (named by Bentham, in honour of Baron 

 Charles de Hugel, of Vienna.) Benth. in bot. reg. under no. 

 1622., but not of Rchb., which is Didiscus. 



LIN. SYST. Pentandria, Monogynia. Calyx tubularly cam- 

 panulate, half 5-cleft, with the recesses hardly membranous ; 



segments rather unequal, linear, stiff, somewhat spinose. Corolla 

 funnel-shaped, with a short exserted tube, a 5-parted limb, and 

 oblong, quite entire segments. Stamens inserted at the throat ; 

 anthers linear, sagittate. Cells of capsule many-seeded. Annual 

 or perennial herbs, clothed more or less with white woolliness. 

 Leaves alternate, linear, entire or pinnatifid. Flowers disposed 

 in dense, corymbose heads ; with the calyxes and bracteas imbri- 

 cate, immersed in dense wool. Hugelia differs from Cilia in the 

 anthers and habit. 



1 H. DENSIFOLIA (Benth. I.e.) plant humble: stem smoothish ; 

 leaves numerous, nearly all pinnatifid, glabrous, with 2-3 acerose 

 segments on each side ; tube of corolla longer than the calyx ; 

 stamens about equal in length to the corolla. Q. ? H. Native 

 of California, Douglas. Corollas blue.

2 H. ELOKGA'TA (Benth. 1. c.) branches elongated, divaricate 

 or procumbent, tomentose ; leaves short, simple, or furnished 

 with 1-2 segments on each side, all clothed with white tomentum, 

 or at length hardly glabrous ; tube of corolla exserted ; stamens 

 exceeding the corolla. 0.?H. Native of California, Douglas. 

 Flowers deep blue.

3 H. VIRGA'TA (Benth. 1. c.) plant erect ; leaves elongated,

 corolla longer than the calyx ; stamens shorter than the corolla.

4 H. LD'TEA (Benth. 1. c.) erect ; lower leaves elongated, 

 simple, glabrous : superior ones short, pinnatifid, clothed with 

 white wool ; corymbs small ; tube of corolla shorter than the 

 calyx ; stamens equal in length to the corolla. 0. ? H. Native

V. LINA'NTHUS (from \ivor, linon, flax ; and a^Soe, 

 nnthos, a flower ; from the resemblance of the flowers to several 

 species of Llnum ) Benth. in bot. reg. under no. 1 622. 



LIN. SYST. Pentandria, Monogynia. Calyx tubular, mem- 

 branous ; with 5 strong, green nerves, which are drawn out into 

 subulate, recurved teeth at the apex. Corolla funnel-shaped; 

 with a short tube, a 5-cleft limb, and obovate segments, which 

 are crenulated at the apex. Stamens inclosed in the tube ; 

 anthers filiform, hardly sagittate at the base. Cells of capsule 

 many-seeded. This is a very distinct genus, from the calyx, 

 anthers, and habit. 



1 L. nicHOTOMUs (Benth. 1. c.) . H. Native of California. 

 Douglas. A glabrous, annual herb. Leaves opposite, sessile, 

 palmate, with 3-5 linear-subulate segments. Flowers solitary in 

 the forks, almost sessile, bractless, but numerous and approxi- 

 mate towards the tops of the branches. Corolla size, colour, 

 and form of Ltnum sujfmticosum.

VI. LEPTOSrPHON (from XJTTOC, leptot, slender; and

 Benth. in bot. reg. under no. 1622. 



LIN. SYST. Pentandria, Monogynia. Calyx tubularly cam- 

 panulate, equal, semi-5-cleft ; lobes linear-subulate, acute ; 

 sinuses membranous. Corolla funnel-shaped ; with a very long, 

 very slender tube, and a campanulate 5-cleft limb, with oval, 

 obtuse, quite entire lobes. Stamens inserted at the throat of the 

 corolla ; anthers oblong, sagittate at the base. Cells of capsule 

 many-seeded. Annual herbs, glabrous at the base, and downy
