MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



the terminal more than 2 mm. long, the lower successively short- 

 ened, all acuminate and acute, gray-hairy. Calyx white, densely 

 pilose, broader than long. Stigmas exceeding the bracts, stout, 

 recurved, pinnately many-parted, bright purple. 



At Canamina, 4,000 feet, 0. E. White, July 30, 1921, without 

 number. "10 to 15 feet high, the juice milky." Species very 

 near A. Douilleana. Named in allusion to the strong contrast, 

 in the spike, between the purple stigmas and Avhite cahrx. 



Acalypha vermifera 



Young portions minutely downy. Stems much branched, the 

 branchlets elongate, slender. Stipules 3 to 5 mm. long, sul)ulate, 

 consisting chiefly of a long awn-like attenuation. Petioles 2 to 

 5 mm. long, very slender. Blades 3 to 7 cm. long, 1 to 2 cm. 

 broad, lanceolate, with rounded base and acuminate and acute 

 summit, sharply short-serrate, thin, deep-green, the slender 

 venation very prominent on the lower surface, the secondaries 

 about 5 on each side, strongly ascending, the reticulation very 

 loose. Spikes numerous, 1 to 2.5 cm. long, 1 mm. thick, subses- 

 sile, the pistillate flower solitary at the base, the stigmas plumose 

 and about as long as the calyx. 



Huachi, 1,800 feet, 0. E. White, September 2, 1921 {no. 944). 

 No. 6688, collected by the author at the same place, September 

 22, "a small tree in cultivated ground," appears to be the same, 

 although the spikes are much smaller and closely sessile. Name 

 in allusion to the caterpillar-like appearance of the inflorescence. 



Acalypha heteromorpha 



(Pistillate plant.) Petioles, etc., minutely papillose, the 

 upper leaf-surfaces sparsely short-strigose, the lower sparsely 

 puberulent. Stems stout, green, irregularly sulcate. Petioles 

 1.5 to 2 dm. long, strongly sulcate. Blades 12 to 18 cm. long, and 

 nearly as broad, ovate with subtruncate or slightly cordate base 

 and a short acutish terminal point, shortly serrate-dentate, with 

 obtuse teeth, very thin, deep-green, all the venation slender, 

 prominent on the low^er surface, the secondaries about 12 on 

 each side, including a nerve-like pair from the base, connected by 

 few straightish tertiaries, all branches connecting to form a 

 strong line close to the margin. Spikes slender, subsessile, soli- 

 tary in the axils, much shorter than the petioles, the pistillate 

 flowers all of one form or of two forms in the same spike, those
