612 UMBELLIFEUiE. Neuropiiyllum. 



Described by De Candolle from sperimens (without mature fruit) collected 

 in the garden of the London Horticultural Society. Hooker asks wliether it 

 may not be Cicuta maculata in a luxuriant state. 



13. EDOSMIA. NiM. mss. 

 Atasnia, Hook. ^ Am. 

 Margin of the cah'x distinctly 5-toothed ; the teeth lanceolate, persistent- 

 Petals broadly obcordate, with a long inflexed point. Stylopodium small, 

 depressed. Styles filiform, deflexed. Fruit oblong or roundish-ovate, 

 laterally compressed. Carpels Avith 5 filiform equal slightly prominent 

 ribs ; the lateral ones marginal. Intervals filled with single thin vittae. 

 Commissure narrow, Avith 2 vittEe. Carpophore free, 2-cleft. Seed semi- 

 terete, nearly plane on the face. — Glabrous perennial herbs ; the root bearing 

 several oblong edible tubers. Stem terete, slender, with few ternately or 

 simply pinnately divided leaves ; the segments narrowly linear. Involucre 

 none or minute. Involucels very small, of several setaceous leaflets. Fruit 

 resembling in taste that of Cicuta maculata. 



" Allied to Carum, particularly to C. Bulbocastanum." Nutt. — We have scarcely 

 a doubt of the identity of this genus and Ataenia of Hooker and Arnott ; but wo 

 know not how these acute botanists ovei'looked the vittte (which in our specimens 

 are abundantly distinct), unless they examined very immature fruit. The name 

 Atsenia being therefore altogether inapplicable, we have felt obliged to adopt 

 that proposed by Mr. Nuttall ; trusting that our esteemed friends who first des- 

 cribed the genus, will accord with us as to the propriety of doing so.

 1—2 (in p. 3—4) oblong-cylindrical tubers, which are sometimes pendulous by 

 a narrow neck." Nutt. Stem 1^-4 feet high, in the tallest specimens 

 scarcely as large as a goose-quill at the base, somewhat branched above, the 

 upper part nearly naked, very smooth and even. Lower leaves on petioles 

 of inoderate length, which are somewhat dilated and sheathing at the base ; 

 the upper ones often undivided : segments almost filiform-linear. Umbels 

 on long slender peduncles ; the rays 6-12, an inch or more in length. Invo- 

 lucre either none, or consisting of several short subulate leaflets. Involucel 

 of 7-9 leaflets, about two-thirds the length of the pedicels. Flowers white, 

 slightly tinged with yellow or red. Fruit rather more than a line long (in /?. 

 longer), contracted at the commissure. Vittte broad, filling up the whole 

 space between the ribs, in p. often tumid.
