globular in form, erect, on a thick, rigid stalk. Three outer sepals yellow 

 inside, and the three inner entirely yellow, as well as the petals and stamens. 

 Jn. Jl. (Nymphaea MX.) 



2 N. Kalxniana Ait. Floating Ivs. with base lobes approximate, submersed Ivs. 

 membranous, reniform-cordate, the lobes divaricate, margin waved, apex retuse ; 

 sep. 5 ; stig. 8 12-rayed, crenate. A smaller species, with small yellow fls., 

 growing in similar situations with the last, Northern States. Dr. Robbins, from 

 whose MSS. the above is quoted, thinks it wholly distinct from N. lutea, (Smith) 

 or any other species. Petiole slender, subterete. Upper Ivs. 2 3' long 1 2^-' 

 wide ; lower Ivs. 3 4' diam. Jl. (Nuphar lutea /3 Kalmiana Torr & Gr.) 



3 IT. sagittaefolia Ph. Lvs. elongated, sagittate-cordate, obtuse ; sep. 6 ; pet. ; 

 anth. subsessile. In slow waters, N. Car. to Ga. (Savannah). Rhizome erect. 

 Lvs. large, 10 to 15' long. Fls. as large as in No. 2. Outer sep. green; inner, 

 yellow and petaloid. 



VICTORIA regia is also a member of this Order, a gigantic "Water Lily, 

 native of the rive.rs of Brazil and Guiana, and successfully cultivated here. Its 

 earliest leaves are linear, then hastate, next sagittate ; its late ones become ovate 

 with a deep slit at base. Thence they gradually become circular and centrally 

 peltate, exhibiting by a distinct line the union of the base lobes. When full grown 

 they are 4 6f diam. (or 8 12f in their native rivers), with upturned edges and 

 prominent veins beneath. The expanded flowers with numerous petals and sepals 

 are If in diameter, 



ORDER X. SARRACENIACE^B. WATER PITCHERS. 



Herls aquatic, in bogs, with fibrous roots, perennial, and with the leaves all radi- 

 cal, urn-shaped, or trumpet-shaped, and large flowers on scapes. Floral envelops 

 4 10, imbricated, the outer greenish, sepaloid. Stamens CO, hypogynous. Carpels 

 united into a several-celled capsule. (Figs. 174, 175, 176.) 



A carious order, chiefly remarkable for the leaves which are of that class called asctdia (308). 

 It embraces at present 8 genera and 6 or S species; the Heliatnpbora of Guiana, the Darlingtonia 

 of California and 



SARRACENIA, Tourn. PITCHER PLANT. (Named in honor of Dr. 

 Sarrazen of Quebec.) Calyx of 5 colored sepals, with 3 small bracts at 

 base, persistent ; corolla of 5, incurved, deciduous petals j stigmas 5, 

 united into a large, peltate, persistent membrane covering the ovary 

 and stamens ; capsule 5-celled ; seeds very numerous, albuminous. 

 Lvs. holding water, with a wing on the front side and a hood (lamina) 

 at top. Scapes 1-flowered, fl. large, nodding. 



Lamina inflected over the throat of the tube IsTos. I, 2. 



Lamina erect or nearly so, throat open.* 



* Leaves ventricous, never spotted with white No. ?. 



* Leaves trumpet-shaped, very tall, often mottled and spotted above .No. 4. 



1 S. psittacina MX. Lvs. short, reclined, with a broad semi-ovate wing : fls. deep 

 purple. Bogs, Ga., Fla. to La. Lvs. 3' to 5' long when the plant is in flower, 

 6 10' when in fruit, slightly mottled with white on the back. The tube is 

 small and nearly closed by the hooded lamina, which gives to the whole leaf 

 the semblance of a parrot, whence the specific name. Scape If high. PI. 

 rather smaller than that of S. purpurea. March. 



2 S. variolaris MX. Lvs. elongated, nearly erect, mottled with white on the 

 back, the wing lance-linear; fls. yellow. -Bogs in pine barrens, S. Car., Ga. 

 (Feay and Pond) and Fla. Lvs. 12' to 18' high, remarkable for their white dia- 

 phanous spots near the top. Tube somewhat ventricous above, nearly enclosed 

 by the strongly inflexed hood ; wing 6" to 12" wide. Scapes shorter than Iva. 

 Fls. about the sizo of the last. Mar., Apr.
