232 Rhodora [November 



Furthermore Muhlenberg, in the same work, h;is descriptions of both 



D. sanguinalis and J), filiformis, the only other species which his 

 description could apply to, so that all told it seems probable that he 

 was describing the plant we have known as I), hum if it.su. Conse- 

 quently I am accepting Schreber ex Muhlenberg as the authority for 

 1). I acinic mum which is without question the correct specific combina- 

 tion for the plant recently treated as I), hum if una. 



Echinochloa CRUSGALLi (L.) Beauv. forma vittata forma nov. — 

 Differt a typo foliis inter nervos virides flavo-viridibus. New Bruns- 

 wick: Shediac Cape, August 19, 191b, house yard, F, Tract/ Hubbard, 

 no. 7(i3 (type, in Herb. Hubb.). Massa< HUBETTS: Stoughton, 

 September 15, 1912, waste ground, in yard, S. F. Blake, no. 4039. 



This plant is at once noticeable on account of its almost golden 

 leaves veined with rather dark green. Otherwise it seems to show no 

 variation from the type. 



Setaria lutescens (Weigel) comb. nov. Pauicum glaucum Auct. 

 non L. P. lutescens Weigel Obs. 20 (1772). S. glauca Auct . as to plant. 

 Chaetochloa lutescens (Weigel) Stunts in I T . S. Bur. PI. Ind. Inv. Seeds 

 & PI. Imp. 31: 36, SO (1914).— As pointed out by Stuntz in the above 

 mentioned article Pauicum f/laucum L. should be applied to the pearl 

 millet which has been called Pennisetum americanum (L.) K. Schum., 

 but now becomes Perm, glaucum (L.) R. Br. The oldest available 

 name for the plant known as S. glaucum is Panicum, lutescens Weigel, 

 •consequently the correct name of our plant is S. lutescens. S. glauca 

 (L.) Beauv. and Chaetochloa glauca (L.) Scribn. are typonyms of Pen- 

 nisetum glaucum. 



Setaria viridis (L.) Beauv. var. Weinmannii (R. & S.) Brand in 

 Koch Syn. Deutsch. PI. ed. 3, 3: 2(590 (1905); Fernald & Wiegand in 

 Rhodora 12: 133 (1910). S. viridis var. brcriseta (l)oell.) Hitchc. in 

 Rhodora 8:210 (1900); Hitchc. in Gray Man. ed. 7, 119 (1908).— 

 As pointed out in Am. Journ. Bot. 2: 181 (1915) it seems undesirable 

 to separate var. breviseta from var. Weinmannii and as the latter is 

 the earliest varietal name which we can apply with certainty to this 

 form it replaces var. breriseta. 



Setaria italica (L.) Beauv. [sensu amplissimo] Agrost. 51, 170, 

 178 (1S12). — This species is most readily distinguished from *S. viridis 

 by the fact that the spikelet in the latter is articulate below the glooms; 

 the complete spikelet shelling out leaving a cup-like receptacle whereas 

 S. italica has the spikelet articulate above the glooms; the fruit only 

 shelling out leaving the glumes and sterile lemma behind. For a 

 complete treatment of 8. italica and variations see Am. Journ. Hot. 

 2: 183—196 (1915) of which variations the following have so far been 

 noted within the Manual range: subsp. BTRAMINEOFRUCTA Hubb. 1 

 and its forma BREVISETA (Doell) Hubb. [Golden Wonder Millet, 

 .treated in the Manual as var. gcrmanica\; subsp. STRAMINEOFRUCTA 



l These combinations wore all made in Am. Journ Hoi. 2: 183 106 (1915).
