fruit than the Asiatic ones, but they are probably hardly varie- 

 ties. Flowers yellow, as in the rest of the species. 



Giant-fennel-Mke Prangos. Clt. 1752. PI. 1 to 2 feet. 



S P. CYLINDRA'CEA (D. C. prod. '4. p. 239.) leaves supra- 

 decompound, rather hairy ; segments or leaflets linear, diva- 

 ricate ; leaves of involucra and involucels undivided, linear; fruit 

 cylindrical, expanded into membranous, entire, subundulated 

 wings ; mericarps 5 times longer than their diameter. 11 . H. 

 Native of Calabria. Cachrys cylindrica, Guss. in litt. 1829. 

 Fruit an inch long ; the section of the mericarps are not semicir- 

 cular, as in P. ferulacea, but somewhat depressed on the back. 



Cylindrical- fruited Prangos. PI. 1 to 2 feet. 



4 P. ui6pTERA (D. C. prod. 4. p. 239.) leaves decompound, 

 glabrous, with the petioles trichotomous ; segments or leaflets 

 linear ; leaves of involucra and involucels linear, spreading ; fruit 

 ovate, with very curled membranous wings. I/ . H. Native of 

 Persia, on rocks at Seidhodzi, in the province of Aderbeidjan, 

 where it was collected by Szowits. Allied to P. ferulacea, but 

 evidently distinct from it in the fruit being one-half smaller ; in 

 the wings being much more curled and white, and in the umbel- 

 lules being more dense. 



Curled-winged- fruited Prangos. PI. 1 to 2 feet. 



5 P. THAPSIOIDES (D. C. prod. 4. p. 340.) leaves supra-de- 

 compound, glabrous : leaflets or segments subulate, stiffish, shin- 

 ing ; leaves of involucra and involucels 5-7, undivided, deflexed ; 

 fruit ovate : having the ribs expanded into thick wings. Tf.. H.

 Thapsia Laserpitii, Spreng. in Schultes, syst. 6. p. 613. It dif- 

 fers from Laserpitium in the petals being yellow, not white, ob- 

 long, not emarginate. Ribs of fruit few. 



Thapsia-j brmed Prangos. PI. 2 to 3 feet. 



6 P. ANISOPE'TALA (D. C. prod. 4. p. 240.) plant glabrous ; 

 leaves decompound : lobes or segments linear, short ; stem 

 nearly naked ; leaves of involucra and involucels ovate-lanceo- 

 late, acute, entire ; mericarps of fruit compressed from the back, 

 oblong : with the ribs expanded into wings, the 3 dorsal ribs 

 attenuated at the base, and somewhat concrete, the 2 lateral ones 

 marginating and broader than the rest. 1. H. Native of 

 Syria, near Nazareth. It is allied to Cachrys odontdlgica, but 

 differs in being glabrous, and in the fruit being winged. Calyx 

 with 5 short teeth. 



Unequal-petalled Prangos. PI. 2 to 3 feet. 



7 P. FCENICULA'CEA (Meyer, verz. pflanz. p. 131.) plant quite 

 glabrous; leaves supra-decompound ; segments setaceous ; leaves 

 of involucra and involucels lanceolate ; wings of mericarps flat : 

 furrows naked. If. . H. Native of Caucasus, among rocks or 

 in stony places, on the higher mountains of Talusch, at the ele- 

 vation of 2000 or 3000 feet. 



Fennel-like Prangos. PI. 2 to 3 feet. 



Cult. The species of Prangos are of easy culture, but grow 

 best in a dry soil. They are only to be increased by seeds, 

 which should be sown in the autumn.

LIN. SYST. Pentandria, Digynia. Margin of calyx entire. 

 Petals oval, entire, involute at the apex. Stylopodium depres- 

 sed, hardly prominent in the fruit. Transverse section of fruit 

 oval ; mericarps compressed from the sides ; commissure narrow, 

 furnished with 2 vittae. Mericarps expanded into 5 vertical 

 membranous wings on the back, with the furrows between the 

 wings broadish, and furnished with one vitta each. Albumen 



involute. Perennial glabrous herbs. Stems acutely triquetrous, 

 at length somewhat spirally twisted. Leaves pinnatifid ; lobes 

 broadly oblong, toothed. Umbels and umbellules of many rays. 

 Leaves of involucra and involucels many, undivided. Flowers 

 golden yellow. This genus, according to Lagasca, in obs. apar. 

 p. 26. is easily distinguished by its character and habit. Perle- 

 bia is a name given to a genus by Martius, and is therefore 

 already preoccupied. Colladonia of Sprengel is a species of 

 Palicourea.

LIN. SYST. Pentandria, Digynia. Margin of calyx with 5 

 very short teeth. Petals ovate, with an inflexed acumen. Stylo- 

 podium 2, distinct, conical, permanent, exserted ; styles subu- 

 late, diverging. Fruit ovate, didymous ; commissure narrow. 

 Mericarps semi-terete, with 5 obtuse fungous ribs, which are 

 muricated with prickles. Seed girded by copious vittse. Albu- 

 men involute, with the central area empty and orbicular. A 

 perennial herb, with the appearance of a species of Angelica. 

 Root a fascicle of tubers. Leaves glabrous, triternate ; leaflets 

 ovate, coarsely toothed. Umbels of many rays, without invo- 

 lucra ; rays unequal, angular. Umbellules of 10-15 flowers; 

 involucels of 5-8 subulate leaves. Flowers white, some of them 

 in each umbellule sterile.

LIN. SYST. Pentdndria. Digynia. Margin of calyx obsolete. 

 Petals obcordate, with an inflexed point. Fruit ovate, villously 

 tomentose ; mericarps with 5 thick, very blunt ribs, and narrow 

 furrows. Seed covered all over .with numerous very fine vittae, 

 convex on the outside, and with a deep involute furrow on the 

 inside. Perennial herbs, hoary from villous tomentum in every 

 part ; referrible to Hernias or Heracleum in habit. Leaves pin- 

 nate ; leaflets lobed : lobes ovate, toothed, decurrent. Umbels 

 and umbellules many-flowered, involucrate. Flowers white. 

 This genus is easily distinguished at once from Cachrys, in the 

 petals being white and obcordate.
