Besmodium uncinatum, Dc., called " Chili Clover", is said by Dr. W. 

 Hillebrand to be valuable for forage. This is a larger plant as com- 

 pared with the last ; its 3-cornered stem is covered with stiff, hooked hairs 

 by means of which it clings to and climbs over bushes ; the flowers are 

 purplish-blue, larger than in other species, being J inch long and more* 



Desmodium gangeticum, Dc. is regarded in India as a febrifuge and 

 anti-catarrhal. This plant grows 3 or 4 feet high ; the leaves instead 

 of having 3 leaflets as usual in the genus, have only one leaflet 3-6 

 inches long ; the pod is notched only on one edge. 



Desmodium gyrans, Dc, which is a native of the East Indies, is also 

 found in Jamaica. It has attracted a great deal of interest from the 

 fact that the two small lateral leaflets make in the course of a few 

 minutes periodic oscillations which are quite independent of the sleep- 

 movement of the large terminal leaflet due to variations in the light. 



THE REPRODUCTION OF THE ORANGE FROM 



SEED. 



By Herbert J. Webber, Special Agent, United States Department of 

 Agriculture, Subtropical Laboratory, Eustis, Florida. 



{Concluded from July Bulletin.) 



Grape Fruit and Shaddock (Citrus decuman a). 



The fruit commonly known in the United States as the Grape-fruit, 

 or Pomelo* a smooth, round fruit, is always reproduced true to the seed. 

 This is so well known to growers of this State, that they never have any 

 hesitation to allow the trees to grow to maturity as seedlings. I have 

 tested the fruit of many seedling trees in all portions of the ^tate, and 

 have almost uniformly found it of good quality. Only a very slight 

 variation can be found commonly between the fruit of such seedlings. 

 The Shaddock, so far as I have been able to learn from growers, also 

 reproduces true, through the seed. 



The Citron (Citrus medica). 



Florida growers have had but little experience with this species, and 

 I have been unable to learn anything regarding its reproduction through 

 the seed. Of this species Gallesio says, " We have seen the Citron tree 

 of the Jews (Citrus medica cedra) reproduced constantly from the seed. 

 It has many seeds, the greater part of which always give Citron trees 

 having constantly the same characteristics in aspect, form, and proper- 

 ties." 



Lemon (Citrus limonum or C. medica limonum). 



This species, while not extensively grown in Florida for commercial 

 purposes, is yet cultivated to a considerable extent. Many growers may 

 be found who have grown lemons from the seed and almost invariably, 

 the testimony is that the fruit from the >eedling is comparatively the 

 sanie as the fruit from which the seed was taken. .No other resuit has, 



*Said by Dr. Morris (Garden and Forezt, 1896, p. 164) to be the Forbidden 

 Fruit of the West Indies — Citrus Paradisi maliformis of Macfadven's class tica- 

 lion.
