long been hunting a place for it, first making it a variety of ^9. cordata, 

 then of S. Banlayi, but it seems specifically distinct from both. It is 

 most nearly related tu 6". cordata, but is by no means like it in habit 

 and can always be easily distinguished. It would more likely be mis- 

 taken for .S". discolor. 



Many other forms, especially hybrids, could be noted, but those 

 given will suffice to show the nature and importance of the work. 

 Again would we urge all botanists who are interested in the welfare 

 of their science to communicate with Mr. Bebb in regard to any 

 specimens or notes they may have that would be a help in studying 

 our willows. — J. M. C. 



Leaven Avortliia in S. W. Missouri and N. W. Arkansas.— 



On a recent trip to S. W. Missouri 1 was rewarded by finding a 

 species of Leavemvorthia growing upon the debris of eroded limestone 

 rocks in rich springy soil. Though growing in rocky places it was 

 not found on the top of flat rocks, the situation usually given in the 

 books for them. I have hunted for them upon all the flat top rocks I 

 could find in N. \V. Arkansas and S. W. Missouri and have not found 

 a single specimen in such a habitat. The specimens were growing 

 W\\\\ Arenaria Pitclieri, Sisymbrium canesceus, occasionally a specimen of 

 Draba cuncifolia. Allium striatum, Oxalis violacea, Astragalus Mexicanus 

 and A. distortus. The following is a description of the species as made 

 in the field from fresh specimens: 



Root single, annual and running deep into the soil ; leaves all 

 ra'Mcal and lyrate-pinnatifid ; peduncles radical, one-flowered, elon- 

 gated, sometimes as many as 20 from one root, 2'-^' high. Sepals 

 more or less reddish-brown with a shade of purple ; some were red 

 dish brown the whole length, others have only a reddish-brown tip 

 with a greenish-yellow base, while others are entirely greenish-yellow. 

 Petals vary from reddish-brown to yellow like the sepals. Those 

 flowers with dark reddish-brown sepals have the corolla distinctly red- 

 dish ; some have a white blade and yellow claw, while some are 

 light yellow throughout. The corolla has lighter corresponding 

 shades than the calyx. Silique narrow oblong-linear, elongated after 

 flowering, sometimes i^' long, flattened parallel to partition, straight 

 in perfect specimens ; sometimes torulose in imperfect specimens. 

 Style about as long as the width of the pod and club shaped; pod of- 

 ten shows a purplish tinge. Seeds broadly winged, orbicular, flat, 

 from 1-9 in each cell. Radicle straight, at an angle of 45° or even 

 at a right angle with the cotyledons. I am mclined to thmk the radi- 

 cle becomes more oblique as the seeds mature. 



The characters seem to apply to L. aurea, Torr., as described in 

 the Gazette, March, ;88o. I obtained excellent fruit specimens 

 and fair flower specmiens, but only a limited number of either. I 

 can furnish a limited number of fruit and flower specimens to botan- 

 ists interested in this genus for twenty-five cents, the specimens in- 

 cluding both flowers and fruit and the postage paid. — F. L. Harvey,
