ment of the growing season, and should be executed with 

 judgment, so that it will last three or four years, as the 

 roots dislike being disturbed. The potting' soil should 

 consist of one-half chopped sod, the balance of equal 

 parts leaf-mold, peat and live chopped sphagnum moss, 

 well mixed together; about one-third of the pot room 

 should be devoted to drainage potsherds or charcoal, 

 covering the same with a little rough material to keep it 

 open. When the large, fleshy roots are carefully dis- 

 tributed the material should be worked in firmly about 

 them, leaving the base of the plant on a level with the 

 rim of the pot when finished. Water sparingly until 

 the new growths appear, when a more liberal supply will 

 be necessary, but never enough to keep the soil con- 

 stantly wet, or the new roots are liable to decay and the 

 foliage to become spotted. Stock is increased by remov- 

 ing the old pseudobulbs, potting them up in small pots and 

 giving them a little more heat and moisture until they 

 start new growth action, when they may be removed to 

 their proper department. ROBERT M. GREY.

CYNANCHUM (Greek, dog poison). Asclepiaddcece. 

 About 20 species in S. Eu., Africa, Asia and Australia, 

 herbaceous or sometimes half woody at the base, twin- 

 ing. Lvs. opposite, entire. Plant very like Vincetoxi- 

 cum, but the fls. differ in having a scale or ligule on the 

 inside of each of the 5 parts of the crown. 



acuminatifdlium, Hemsl. ( Vincetdxicum acumindtum, 

 Decne. V. Japdnicum, Hort. ). MOSQUITO PLANT. CRUEL

 ing a somewhat twining habit: the stems grayish and 

 more or less angular: Ivs. opposite, broadly ovate and 

 acuminate, short-petioled, strongly pinnate-veined, en- 

 tire, usually conspicuously gray-pubescent beneath : 

 fl. -clusters lateral (1-2 between the Ivs.), shorter than

 weed-like follicle. Japan. In the flowers, mosquitoes 

 and other insects are caught, much as they are in other 

 asclepiadaceous plants. The native Amsonia Tabernce- 

 montana is sometimes sold as this plant, and it has 

 been figured as such. L. H. B.
