slightly expanding and connate with that of opposing leaf; green, 

 beneath paler, with scattered pubescence on both surfaces. Corymb 

 leafy-bracted at base (the primary flowers sometimes not developed) , 

 its secondarj^ branches (one or both developed) long, once or twice 

 dividing and bracted throughout with reduced leaves. Peduncles 

 and pedicels hirsute with yellowish-white dark -jointed hairs. Calyx 

 6 mm. long, the lobes ovate, acute, serrate (with shallow callous- 

 tipped serratures), densely hirsute. Corolla: the posterior lip 

 2-3 mm. long, 4 mm. wide, arched, the two lobes united and hooded, 

 but not to apex (leaving a slit- like aperture into hood), anterior 

 Up 15-21 mm. long, 14-18 mm. wide, narrowed at base, with narrow 

 orifice, hooded almost entire length (sac strongly upcurving against 

 hood); externally pubescent with short hairs on posterior lip, with 

 longer hairs on base of anterior lip, within pubescent at base. Fila- 

 ments very short or not developed. Anthers straight, 4 mm. long, 

 the two sacs separated on two arms of the connective; posterior 

 sac 1.5 mm. long, yellowish, opening throughout, fertile, concealed 

 within hood; anterior sac short, orange-yellow, sterile, projecting 

 into the orifice, the club-like dark connective-arm serving as a lever 

 against which entering insect pushes, thus forcing the fertile sac 

 out through the slit- like aperture of the hood and against back of 

 insect. Style 2 mm. long. Capsule 6 mm. long, globose pyramidal, 

 obtuse, pubescent with glandless hairs. Seeds .6-.7 mm. long, 

 oblong, obtuse, ridge-angled, brown.

18. Fagelia pinnatisecta Pennell, sp. nov. 



Stem ascending, 2-6 dm, tall, little branched, pubescent above 

 with many-celled dark-jointed not or scarcely gland-tipped hairs. 

 Leaves 3-5.5 cm. long; the blades acuminate at apex, pinnatisect 

 (cut nearly to midrib) with three pairs of lanceolate, irregularly 

 serrate -dentate segments, (the odd terminal segment largest) 2-3.5 

 cm. long, 2-3 cm. wide; each on a petiole 1-2 cm. long, narrowly 

 winged, somewhat hirsute, proximally slightly expanding and con- 

 nate with that of opposing leaf; green and pubescent above, beneath 

 pale, and hirsute pubescent on the main veins, sparsely so over sur- 

 face. Corymb leafy-bracted at base (the primary flowers not
