The spathes are white and green, 

 and somewhat resemble those of 

 A . nepentltoides in shape. {Bot. Mag.

ARISARUM {aris, and aron, Greek 

 names for Arum). Nat. Ord. Aroi- 

 dece. — A small genus of curious, 

 hardy, herbaceous perennials with 

 tuberous root-stocks and long-stalked 

 rounded hastate or sagittate leaves. 

 The only species of any note are 

 A. prohoscidenm {Bot. Mag. t. 6634), 

 which is a native of S. Italy, and has 

 greenish spathes; and A. vulgare 

 {Artim Arisarum) from S. Europe, 

 with livid-purple spathes {Bot. Mag. 

 t. 6023). They both grow in well- 

 drained peaty soil, and may be in- 

 creased by division or seeds. Only 

 fit for botanical collections. 



ARISTOLOCHIA {nristos, best ; 

 locheia, parturition ; in reference to 

 its supposed medicinal characters) 

 BiRTHWORT. Nat. Oi-d. Aristoloch- 

 iacese. — This genus consists of 

 several species, some of which have 

 tuberous root-stocks. The flowers 

 are remarkable for their peculiar, 

 more or less triangular cup-shaped 

 forms and strange colourings — some 

 blossoms being a foot and more 

 across, and 18 to 24 ins. long, while 

 others like those in the Dutchman's 

 Pipe {A. Sipho) are comparatively 

 very small. Some species like the 

 British A. ClematUis, and the N. 

 American A. Sij^ho, and A. tomentosa 

 are quite hardy ; but most of them 

 require the protection of a warm 

 greenhouse or stove. The stems 

 are climbing, and in some kinds 

 attain great lengths. The leaves 

 are usually heart-shaped or lobed. 

 Most of them flourish in a compost 

 of sandy loam and peat, and may be
