Widely planted in gardens, but found wild in a few localities. — Dalzell notes that it 

 occurs wild on Miradonger, near Fen in the Konkan, where it has also been found by 

 Woodrow. I have found it in the Deccan on the banks of the Koina river below 

 Mahableshwar far removed from any habitation. 



The dimorphism of the sexual organs of Ecinwardtia trigijna has been treated of by 

 Alefeld in 13otan. Zeit. (1SU3; p. 28ji. Sir Henry Collett in 1884 made a careful and 

 exhaustive examination of upwards of 100 fresh specimens from tiie hills below Simla, 

 and the subjoined table gives the forms which he has been able to differentiate (MS. 

 in Herb. Kew.). 



A. Long-styled forms. 



Stamens in 2 rows, 3 of the stamens being distinctly longer than the other 2. 

 («) Styles 3 ; stamens about half as long as the styles. 



(h) Styles 4, three long and one short, the latter equalling the longer stamens, 

 (f) Styles h, three long and two short, the 2 shorter equalling respectively the 

 long and short stamens. 



B. Short-styled forms. 



Stamens in 2 rows, three being distinctly longer than the other two. 

 (a) Styles 3, equalling in length the 2 shorter stamens. 

 (/') Styles 3, standing below the 2 shorter stamens, 

 (c) Styles 7, standing below the 2 shorter stamens. 



{d) An abnormal form with all 5 stamens of sliglitly unequal lengths ; the 3 

 styles on a level with the shortest stamen. 



C. All the styles and stamens of the same length. 



Sir H. CoUett's observations make it evident that the species R. tetragyna can 

 scarcely be maintained as a separate one, a fact long since susi^ected by Hooker (Fl. 

 E. I. v. 1, p. 412 under R. tetragyna). 



3. HUGONIA, Linn. 



Scandent shrubs, often tomentose. Leaves alternate, penninerved, 

 stipulate. Inflorescence various ; flowers yellow, the 2 lowest peduncles 

 of each branch converted into spiral hooks. Sepals 5. Petals 5, hypo- 

 gynous, contorted, fugacious. Stamens 10, connate at the base into a 

 short tube, with glandular swellings between the petals. Ovary 5-celled ; 

 ovules 2 collateral in each cell ; styles 5, filirorni, stigmatose at the 

 apex. Drupe globose, fleshy or baccate. Seeds compressed, albuminous ; 

 embryo straight or slightly curved ; cotyledons flat ; radicle short. — 

 DisTKiB. Tropical Asia and Africa ; species 6. 



1. Hugonia Mystax, Linn. Sp. PI. (1753) ]). 675. A rambling 

 scandent shrub; branches yellow-tomentose, with short horizontal 

 branchlets, leafless below and provided near the ends with a pair of 

 circinate hooks. Leaves lv--i by 1-1 i in., elliptic-obovate, obtuse or 

 subacute, entire, reticulatefy veined, the veins conspicuous on both 

 surfaces, glabrous, base tapering; petioles ,L ^^- '""S' hairy; stipules 

 lanceolate-subulate. Plowers at the extremities of the short branchlets 

 1-1^ in. across, terminal and in the upper axils; pedicels short, 1- 

 flowered, clothed with soft yellow hairs. Sepals f'^, in. long, ovate- 

 lanceolate, acute, fulvous-pubescent. Petals many limes longer than 

 the sepals, thin, ovate-oblong, acute or truncate. Styles longer than the 

 stamens ; stigmas capitate. Drupes about | in. in diam., globose, sur- 

 rounded by the persistent sepals ; pulp scanty ; stone bony, grooved,
