61. LOGANIACEiE. 



[Shychnos, 



A large deciduous tree, attaining 100 ft. iu height, spinous, sometimes 

 without spines. Bark thin, grey, smooth or rough with minute open 

 lenticels, sometimes exfoliating in thin, curly scales. Green cells developed. 

 Wood brownish grey, hard, durable with a bitter taste. Pores of 2 classes, 

 large branched ducts and small pores in irregular ramified or branched 

 patches, joined by concentric, irregular bands of white tissue. Medullary 

 rays moderately broad and fine, distinct. Weighs 60 lbs. to the cub. ft. 

 Seeds yield the poisonous alkaloid strychnia. This tree is common on 

 laterite along the sea-coast where it exists protected by its poisonous 

 qualities. The Haigas in North Kanara do not use the branches of this 

 tree for leaf manure as the strong, sharp, short axillary spines wound the 

 feet of the cattle in the cattle sheds.
