celled : calyx glabrous ; segments lanceolate, acuminate : corollas 

 white or pale purple ; petals less than i cm. long : anthers linear, 

 6 mm. long, spurred at the base : capsules subglobose. 



In sandy soil, Georgia and Florida. Summer. 



While collecting along the southern border of Georgia I met 

 this delicate little species of Rhexia at various places. It is related 

 to Rhexia lanceolata but is smaller and all its parts are much 

 more slender. The linear-filiform or filiform leaves, the small 

 corollas and the glabrous calices are all diagnostic characters 

 readily separating Rhexia filiformis from Rhexia lanceolata. 



» COXRADINA PUBERULA 



A much branched shrub, 3-7 dm. tall : foliage cinereous-pu- 

 berulent : leaves numerous, often clustered in axils ; blades nar- 

 rowly linear, 1-2.5 cm - l°ng, obtuse, entire, strongly revolute, 

 sessile : clusters 2-6-flowered, often forming a continuous raceme ; 

 pedicels commonly 1-2 mm. long: calices 5-6 mm. long, puberu- 

 lent, tubes slightly ribbed ; upper lip with 3 ovate or ovate-lanceo- 

 late acute ascending teeth ; lower lip with 2 lanceolate-subulate 

 teeth: corollas 12-15 mm. long; tube as long as the calices or 

 nearly so ; upper lip retuse ; lower lip 3-lobed, lateral lobes 

 rounded, middle lobe cuneate-flabellate, deeply notched : nutlets 

 1 mm. long, globose-oval, smooth and glabrous. 



In sand, Florida. Spring and summer. 



Conradina is not a monotypic genus, for it is perfectly clear 

 that two distinct species have been associated under the name 

 Conradina c ones c ens. Both species are peculiar to Florida, and 

 the one heretofore undescribed is apparently the more widely dis- 

 tributed. Conradina puberula may be distinguished from Conra- 

 dina canescens at a glance by the larger size of all its parts and the 

 Puberulence of its foliage, hirsute pubescence being usually absent 

 and being found, if present, only about the mouth of the calyx. 

 The calyx is longer than that oi Conradina canescens. Prominent 

 characters exist in the corolla, in which the upper lip is retuse and 

 the middle lobe of the lower lip is cuneate-flabellate and deeply 

 notched. In Conradina canescens the upper lip is rounded, and the 

 funded middle lobe of the lower lip is not prominently produced
