terminal umbel, ped. f in., glabrous, bracts small, linear; cal,- 

 segm. linear, acuminate, slightly ciliate, cor. rather over i in. 

 diam., rotate, flat, star-like, lobes shallow, broadly triangular, 

 with a short acuminate tip, surface densely velvety; column 

 depressed, coronal lobes falcate, acute, processes longer, oblong, 

 closely folded over anth. ; follicles 4-4^ in., somewhat divari- 

 cate, linear, glabrous; seeds | in., oval, coma over i in. 



Intermediate region on rocks; very rare. Hewahette (Moon); 

 Kurunegala. Fl. Jan., June ; deep red-purple. 



Endemic (?). 



The fl.-bud is 5-angIed and quite flat, the cor.-lobes being folded down 

 from the base so that the points meet in the centre. Thwaites considered 

 B. campatiidata and B. wnbellata as mere synonyms, but the latter is a 

 stouter plant and has the corolla marked with transverse yellow lines. 



LXXXVL— LOGAN I ACE.E. 



Trees or shrubs, rarely herbs, 1. opp. (or in threes) entire, 

 with or without stip., fl. regular, bisexual, usually in cymes; 

 cal. free, segm. 4 or 5 ; cor.-lobes 4 or 5, valvate or imbricate; 

 stam. 4 or 5, inserted in cor.-tube; ov. superior (or half-inferior 

 in Gaertnera) i or 2-celled, with i or many ovules in each 

 cell, styles i or 2 ; fruit usually fleshy, indehiscent, rarely a 

 capsule ; seeds i, 2, or many, embryo straight, in copious 

 endosperm. 



Annual herb ; fruit a capsule . . . .1. Mitrasacme. 

 Trees or shrubs ; fruit a berry. 

 Ovules numerous in each ov.-cell. 



Lobes of cor. contorted 2. Fagr^a. 



Lobes of cor. valvate 3. Strychnos. 



Ovule solitary in each ov.-cell . . . .4. Gaertnera. 



This family differs from RubiacecB in little but its superior ovary, and 

 even this character is not absolute. Our four genera are more or less 

 parallel to the following Rubiaceous ones : — i. To Oldenlandia, 2. to 

 Gardenia or Randia, 3. to Carissa, not closely, and 4. to Psychotria or 

 Saprosma. 



We have fourteen species. All those of Strychnos occur in the low 

 country, four being restricted to the dry region and two to the moist, one 

 of the latter extending also into the hill-country. The four species of 

 Gaertnera are all confined to the moist region, two in the low country 

 -and two montane ; one species of Fagrcea also extends into the montane 

 zone ; Mitrasacme is a low-country plant. Of our species five, or perhaps 

 ■six, are endemic.
