102 FUMITORY FAMILY 



Sepals united into a cap, which falls off as the flower opens. 

 Capsule 1-celled, many-seeded. 



Our well-known Poppy blooms as an annual in warm sand 

 near Bridal Veil Falls, where seed has doubtless been acci- 

 dentally introduced, and also occurs, in a perennial form, at 

 Wawona, where it is apparently native. It is the same spe- 

 cies which is so common and beautiful at lower altitudes. 



2. PLATYSTEMON. 



1. P. californicus Benth. Cream-cups. Leaves chiefly 

 basal, elliptic to oblanceolate, ^ to 1 in. long, the upper ones 

 narrower and smaller. Flowers cream-yellow, V\ to nearly 

 Yi. in. long, on pedicels 3 to 5 in. long. Sepals 3. Petals 6, 

 withering and closing about the forming fruit. Pistil break- 

 ing up at maturity into 6 to 20 separate parts. 



The Cream-cup is a hairy annual with many spreading 

 branches from the base. It grows sparingly in the Yosemite 

 with the Poppy and may be expected in warm soil along our 

 lower borders, since it is very plentiful throughout the foot- 

 hills and valleys of California. 



FUMARIACEAE. Fumitory Family. 

 Glabrous perennial herbs with compound finely lobed 

 leaves and irregular perfect heart-shaped flowers. Sepals 2, 

 small. Petals 4, the inner pair narrower than the outer and 

 united by their tips over the stamens and style. Stamens 6. 

 Ovary superior, developing into a 1-celled capsule. 



1. DICENTRA. 



1. D. formosa DC. Bleeding Heart. Leaves all from the 

 creeping rootstock, compound and many 

 times cut into acute lobes, 3 to 9 in. 

 long and nearly as wide, the petiole 4 

 to 12 in. long. Flowering stems ex- 

 ceeding the leaves, naked, terminated 

 by a narrow panicle of rose-purple 

 flowers. Corolla flattened, ^ in. long, 

 cordate at base; tips of outer petals 

 slightly spreading, ]4 in- long. — Shaded 



woods at low altitudes: Merced Grove; Yosemite Valley. 



2. D. uniflora Kell. Leaves all from a cluster of fleshy 

 tuber-like roots, compound, the leaflets divided into obtuse 

 lobes, 2 in. or less long, the petiole 1 to 3 in. long. Flowering 

 stems 1 to 4 in. high, naked, terminated by a single (rarely 2)
