may be grown as faf north as Philadelphia. C. Thomsonae is also 

 planted for ornament in Bermuda and is seen in cultivation in the 

 West Indies and Trinidad. It may be grown from seed or pro- 

 pagated by cuttings and deserves a high rank among ornamental 

 plants for its showy and decorative inflorescence. 



Mrs. Thomson's clerodendron is a strong-growing vine, reaching 

 ten to twelve feet, with stout, fleshy stems ; its leaves are large and 

 petiolate, often six inches in length, opposite in pairs, with entire 

 margins, smooth and glossy, of a dark rich green. The flowers grow 

 in large loose cymes, hanging alternately in regular clusters. The 

 calyx is nearly an inch long, five-parted and persistent, pale yel- 

 lowish green, changing to pure white when in flower and becoming 

 a faded rose-color when in fruit. The corolla is tubular at base 

 with a brilliant, cardinal red, five-parted limb, which is unequally 

 split with the four stamens exserted from the fissure; these are in 

 two pairs of unequal length and long-exserted. The ovary is four- 

 parted and the fruit a glossy black externally with a brilliant red 

 aril uniting the four carpels.
