 ventricose, with long black spines all over the stem, and a handsome head of 

 very fine foliage; the leaves, 9 to 12 feet long, are gracefully drooping. The 

 abundant round fruits are yellowish brown and 2 inches in diameter. The 

 pulp of the fruits and kernels of the seeds are edible, and a valuable oil is ob- 

 tained from the latter. Handsome walking sticks are made from the stems.

51744 to 51747. Aconitttm spp. Ranunculaceae. Monkshood. 



From Edinburgh, Scotland. Seeds presented by Dr. Isaac Bayley Balfour,

51744. AcoNiTUM FEROX Wall. 



A plant with an erect stem 3 to 6 f^t high, rounded, palmately trifid 

 leaves cut into irregularly indented lobes. The large pale-blue flowers 

 are in a terminal dense-flowered raceme. The mass of the root sold by 

 Indian druggists as aconite is derived from this species. The active prin- 

 ciple in the root is an alkaloid, pseudoaconitine. It is used as a narcotic 

 sedative, as an external application for neuralgia, etc., and internally 

 chiefly in the treatment of chronic intermittent fevers. (Adapted from 

 Watt, Dictionary of the Economic Plants of India, vol. 1, p. 87, and Na- 

 tional Standard Dispensatory, p. 98.)

51745. AcoNiTUM riscHERi Reichenb. 



As a garden plant this is at once one of the best, and well worth grow- 

 ing in any collection of hardy plants. The growth reaches 4 to 6 feet, 

 terminated by a fine panicle of large, showy pale-blue flowers. It is an 

 autumn-flowering species from Siberia and Kamchatka. 



Medicinally, this plant is known as Japanese aconite and is imported 

 quite largely into Europe, frequently finding its way to the United States. 

 The Japanese aconite contains as its active constituent an alkaloid called 

 japaconitine, which is now generally believed to be identical with aconi- 

 tine (the alkaloid in A. napellus). (Adapted from Flora and Sylva, vol. 

 1, and National Standard Dispensatory, pp. 98 and 101.) 



51746. ACONITUM SEPTENTRIONALE Koello. 



A plant native to the Himalayas from Chitral to Kumaon, mostly in 

 forests, locally abundant at altitudes of 5,000 to 12,000 feet in Kashmir. 

 The root is perennial, elongate; the stem erect. 3 to 6 feet high, much 

 branched. The fiowers are pale yellow or dull purple, with a short-beaked
