in any form we have yet seen, while even the lower ones are broader than in H. laciniatum, DC, which we 

 consider a mere variety of this species. 



1. Ferula fmniculacea. Nutt Hook. Fl. Bor. Am. 1. p. 268. 



Hab. Snake Country. Mr Tolmie. 



2. F. macrocarpa ; pedalis, puberulo-glaucescens, foliis ternatim compositis, laciniis 

 lato-linearibus decurrentibus basi angustatis apice acutissimis, involucro oligophyllo 

 caduco, involucelli vix dimidiati foliolis oblongo-lanceolatis arete reflexis, fructibus ovato- 

 oblongis pedicello longioribus. 



Nearly allied to the larger specimens of F. fteniculacea, from Carlton House, but the leaves are much less 

 compound, and the ultimate segments longer. 



3. F. caruifolia; acaulis, glabra, virens, foliis latissime vaginatis supra decompositis, 

 laciniis lineari-acuminatis, petiolo perbrevi, scapo folio paullo superante, involucro nullo, 

 involucello magno monophyllo 10-12-partito, laciniis obovatis coloratis venosis erectis 

 umbellam floriferam obvallantibus, fructibus lato-ellipticis. 



A very remarkable species, quite free from glaucescence, with extremely large sheathing bases to the leaves, 

 the divisions of which Tesemble those of Carum Carui, and with an involucellum large in proportion to the 

 umbels. The disk of the back of the fruit is much broader than the wing, whereas, in the two preceding 

 species, they are pretty nearly equal. 



4. F. parvifolia; subcaulescens, glabra, foliis radicalibus petiolum subsequantibus 

 circumscriptione deltoideis tripinnatifidis, laciniis ovatis acuminatis incisis patentibus, 

 caule subnudo foliis 3-4-plo longiore, involucro oligophyllo vel nullo, involucello sub-8- 

 phylio, foliolis lanceolato-subulatis erectis, fructibus late elliptico-obovatis. 



The leaves are small, not more than an inch and a half long, on slender petioles of the same length. The 

 flowers are bright yellow. The disk of the fruit is scarcely so broad as the wing. We may here notice, that 

 F. Palmella, Hook. Fl. Bor. Am., is Cyncopterus glomeratus, Nutt.

Nuttall (PI. Rocky Mount, p. 27) refers this to Eulophus, but the fruit seems very different. He describes 

 there two species, one glabrous and caulescent ; this, although not figured in the Flor. Bor. Am., was considered 

 a mere form of S. triternatum ; the other of Nuttall seems only to differ from our plant by being puberulous, 

 while the true S. triternatum is quite glabrous. 



1. Caucalis microcarpa; piloso-hispida, foliis tripinnatifidis, umbella 4-5-radiata, 

 involucri foliis sessilibus folia caulina simulantibus, umbellse radiis fructiferis 3-4-plo 

 brevioribus, umbellulis 5-7-fidis, involucelli foliolis 3-4 linearibus, fructibus oblongo- 

 ellipticis parvis, aculeis brevibus apice uncinatis. 



This has much the appearance of Anthriscus vulgaris, but wants the beak to the fruit ; it resembles like- 

 wise C. daucoides and leptophylla, but the fruit is much smaller, and the leafy involucre is a peculiar charac- 

 ter. Some of the young specimens are only two or three inches high, but one in fruit is upwards of a foot.
