COB^A 



P. flavum. — A native of New Mexico, 

 simple or branched stems 2-3 ft. high, 

 covered on the upper parts with a loose 

 tomentum of wool. Leaves pinnate, with 

 multijugate, elliptic lance-shaped acute 

 leaflets. Flowers in September, pale 

 yellow, 1 in. across, funnel beU-shaped, 

 in corymbose cymes. A hybrid called 

 flavo-cmruleum has been obtained be- 

 tween this species and P. ccerulenm. 



Culture dc. as above. 



P. humile (P. Bichardsoni ; P. villo- 

 sum). — A beautiful Kocky Mountain spe- 

 cies about 6 in. high, with numerous leafy 

 downy stems. Leaves divided into bluntly 

 ovate leaflets having a faint musk scent. 

 Flowers in July, blue or purple, in droop- 

 ing corymb-like panicles ; coroUa lobes 

 ovate acutish. 



Culture etc. as above. 



P. mexicanum. — A North American 

 perennial with loosely branched stems 

 about 9 in. high, and downy pinnate 

 leaves having ovate or oblong leaflets. 

 Flowers in April, blue, somewhat rotate, 

 bell-shaped, few, in corymbose clusters. 



Culture d-c. as above. 



P. pauciflorum. — A Mexican peren- 

 nial l-lj ft. high, with glandular downy 

 stems, and pinnate leaves cut into narrow 

 lance-shaped acute leaflets about 1 in. 

 long. The flowers are about li-2 in. 

 long, fannel-shaped, and of a yellow colour 

 tinged with red on the outer surface. 



Culture d-c. as above. 



P. pulchellum (P. pulcherrirmmi). — 

 A native of the Eooky Mountains closely 

 related to P. humile, from which it differs 

 chiefly in having usually smooth and 

 naked leaflets, and smaller violet or 

 lavender-blue flowers, or nearly white in 

 some forms. 



Culture dc. as above. 



P. reptans. — A North American peren- 

 nial about 6 in. high, with creeping roots 



and smooth spreading stems. Leaves 

 pinnate, composed of 7-11 ovate acute 

 smooth leaflets. Flowers in April, blue, 

 sometimes white, drooping, in loose pani- 

 cled corymbs, with wedge-shaped corolla 

 lobes. 



Culture dc. as above. 



COB JEh (Cups and Saucers). — A 

 small genus of smooth oKmbing plants, 

 having alternate pinnately cut leaves 

 with terminal tendrils. Pedimcles long, 

 1-flowered, solitary or in pairs in the 

 leaf axils. Calyx tube short, 5- ribbed or 

 winged, with 5 large leafy lobes. CoroUa 

 broadly bell-shaped or cyUndrical, with 

 short spreading lobes. Stamens 5, pro- 

 truding. Disc fleshy, 5-lobed. Capsule 

 ovoid or oblong leathery with 2 or more 

 seeds in each cell. 



C. scandens. — A beautiful Mexican 

 climber having leaves composed of 3 

 pairs of elliptic sUghtly eiUated leaflets, 

 the lower pair near the stem, and some- 

 what lobed on one side near the base. 

 Flowers from May to October, large beU- 

 shaped, with a short, dark purple tube, 

 and short roundish spreading lobes. There 

 is a beautiful form with variegated 

 foliage. 



Culture and Propagation. — This 

 attractive plant is a well-known orna- 

 mental greenhouse climber, but in mild 

 southern parts it wiU stand the winter if 

 not too severe. In the course of the 

 season it will cover a good deal of space 

 and may be used with effect on arbours, 

 trellises &c., or over walls. I have known 

 plants to survive mild winters iu the 

 Thames Valley, although the stems were 

 cut down to the ground. As it is very 

 easily raised from seeds sown in gentle 

 heat in spring, it may be treated as an 

 annual in most parts of the country, 

 being planted out at the end of May or 

 begiiming of June, and left till cut down 

 by the frost. Any ordinary garden soil 

 vnll suit it. 



LXXVII. HYDROPHYLLACEiE— Nemophila Order 



An order of annual or perennial herbs with radical or alternate, rarely oppo- 

 site, entire, toothed, or pinnately, rarely palmately, lobed or dissected leaves. 

 Flowers hermaphrodite, regular, chiefly blue or white in one-sided cymes or 

 racemes, mostly without bracts, and coiled from the apex when young. 

 Calyx inferior, deeply divided, with 5, rarely more, lobes or segments. Corolla 

 gamopetalous, funnel-, salver-, or bell-shaped or rotate, with 5, rarely more,
