UMBELLIFEB^. 259" 



1. Tuberous Bunium. Bunium flexuosum, With. 

 (Eng. Bot. t. 988.) 



The perennial stock consists of a glohular tuber, known by the name of 

 Harthnut or Pignut ; the annual stems erect, slender, glabrous, 1 to near 2 

 feet high, with a few forked branches. Kachcal leaves few and decaying 

 early, with 3 long-stalked segments, each once or twice pumate ; the idtimate 

 divisions short, narrow, pomted, entire or 3-lobed. Stem-leaves few, ■with 

 narrow-linear divisions; tlie central lobe of each segment much longer 

 than the lateral ones. Umbels terminal, or one opposite the last leaf, of 

 6 to 10 rays. The ribs and vittas of the fruit are scarcely perceptible. 



In woods and pastures, chiefly known as a west European plant, possibly 

 extending eastward to the Caucasus, but there is some uncertainty as to 

 the identity of the eastern species referred to it. Much more common in 

 Britain than the tuberous Carum, which is also known under the name of 

 Pignut. Fl. summer. 



XXXII. CHERVII.. CHJEKOPHYLLUM. 



Leaves dissected. Umbels compound, with partial involucres of several 

 bracts, and white flowers. Frmt narrow-oblong or linear, contracted at 

 the top, and sometimes forming a beak alwaj'S much shorter than the seed. 

 Carpels with 5 ribs, sometimes only apparent at tlie top, either without 

 vittas or with one vitta under each interstice. Seed marked with a longi- 

 tudinal furrow on the inner face. 



A considerable and rather natural genua, widely diffused over the north- 

 em hemisphere without the tropics. It is usually cUvided into two, ChcBro- 

 phyUum, with a vitta between each rib ; and -Ire^/i/'j-scifs, without vittas, and 

 the ribs themselves scarcely visible, except at the top, when the fruit is 

 beaked ; but the distinction is purely artificial. 



Umbels on short, lateral pedonclea. Fruit short, hispid 3. Burr C, 



Umbels terminal. Fruit long, glabrous. 



Lobes of the leaves rather obtuse. Ribs and vittas of the fruit conspi- 

 cuous when dry t 1. Hough C. 



Lobes of the leaves pointed. Fruit very smooth, without ribs or vittas 2. Wild C. 



The garden Chervil (C sativum, Eng. Bot. 1. 1268 ; Antkriseus Cerpfolium, 

 Brit. FL), a native of south-eastern Europe, may occasionally be found in 

 waste places near where it has been cultivated. It is a more slender plant 

 than the tvild C, the leaves more dissected, with shorter segments, the umbels 

 mostly lateral and sessile, and the fruit evidently beaked. 



1. Rough Chervil. Chserophyllum temulum, Linn. 

 (Eng. Bot. t. 1521.) 



An erect biennial, 2 to 3 feet high, and rough with short reflexed hairs. 

 Leaves twice pinnate or temate, with ovate or wedge-shaped, piunatifld or 

 toothed segments, more or less hairy, especially on the upper side ; the lobes 

 short and rather obtuse, never elongated and pointed as in the ioild C. and 

 the sweet Cicely. Umbels of few rays, witliout a general involucre ; the 

 partial involucres of 5 or 6 broadly-lanceolate bracts, shorter than the 

 pedicels. Outer petals of the umbel rather large. Fruit the size of that of 

 the wild C, but with 5 obtuse ribs and vittas between them.
