 hitlierto recorded tor the State. (1) Calainlrinia cauleacens H.B. et K. var.

 rear Young (R. NLxon, Sept., 1913), Hawkesbury Agi-ieultural College, "Intro- 

 duced with American hay" (C. T. Musson. Oct., 1917), Deniliquin (W. C. Went- 

 worth, Oct., 1920) and Canoblas, "It produces small shiny black seeds in such 

 quantity as to cover the ground under the plants. Stock eat it and at the stage 

 when it is well ripe they seem to eat up the seeds as well". (W. C. Clark, Oct.,. 

 1920). (2) Sisymbrium altissimum L., "Tumbling Mustard;" a tall twiggy plant 

 belonging to Cruciferae, from Cudal. When mature, the stems break off near the 

 surface of the ground, and the plants are tumbled about by the wind, hence the 

 vernacular name. The first botanical record tif this plant is from tlic northern 

 shores of the Mediterranean Sea, but it is now common throughout Europe, 

 Northern Africa, Western Asia, the United States of America and Canada. Ii. 

 these countries it is a very troublesome agricultural weed, and every effort is 

 being made to eradicate it. (3) Orthocarpus purpurascens Benth. (4) 0. 

 prianthus Benth., family Scrophulariaceae. Both plants are indigenous to Cali- 

 fornia. They were first brought under notice by Mr. C. T. Musson, of the 

 Hawkesbury Agricultural College, in 1916, having come up in the vicinity where 

 stock had been fed on American hay. The former has been collected from the 

 same locality by Mr. W. M. Came this year, and also from Trangie Experiment 

 Farm (C. A. Linden.).

 Araceae, a native of Tropical America, with perforated leaves (c.f. Aponogeton

 edible when ripe, and the plant can be grown near Sydney.
