300 PROCEEDINGS OP THE AMERICAN ACADEMY 



Florida; and am disposed to think the same of A. pedunculare, 

 HBK., or what passes for that species. 



A. Jacquini, Don, {Lavatera Americana, L., Sida abutiloides, 

 Jacq. Obs. t. 7, aS'. crassifolia, L'Her. Stirp. t. 60, Abutilon lignosum, 

 A. Rich. Fl. Cub., and Griseb., to which may be added A. hypoleucum, 



long, little shorter than the yellow corolla : carpels 5, or not rarely 6 to 10, obo- 

 vate-oval after dehiscence, the sides soon obliterated: seed puberulent. — S. Ari- 

 zona to Texas, Wright, Thiirber, Havard. 



A. ABUTILOIDES. Taller and stouter, 3 or 4 feet high, canescent, and branches 

 with some loose hairs : leaves all cordate, crenatelj'^ serrate, caudate-acuminate, 

 uppermost lanceolate : calyx 2 or 3 lines long, the lobes broadly ovate and apicu- 

 late: petals 4 or 5 lines long, obovate, yellow changing to pinkish in drying: 

 carpels 5 to 7, when mature 2 lines high and less deep, obscurely umbonate, 

 septicidaliy separating almost whole, the diaphanous inner walls tardily break- 

 ing up and uncasing the puberulent seed, the permanent dorsal portion deep- 

 cymbiform, thin-membranaceous with thicker and firmer summit, disposed to 

 split down the back into two valves. — Santa Catalina Mountains, S. Arizona, 

 Pringle, 1882, distributed as " A. pentaschista " and as " Sida Beiiandieri, var." 



§ 3. Cleistanoda. Seed (wholly smooth and glabrous) completely and per- 

 manently invested by a firm corrugate-reticulate or at length clathrate (doubt- 

 less endocarpial) arilliform covering: habit, flowers, and pubescence of § 2. 



A. PARViFLORA, Cav. Ic. V. 19, t. 431. Petals "yellow," but in dried speci- 

 mens seeming ratlier to be purplish : radiate summit of fruit liirsute-pubescent, 

 and with short cusps or points ; dorsal and permanent portion of carpels com- 

 paratively firm in texture with a stout midrib below, or basal part reduced to a 

 very stout rib. — Mexico. Structure of the fruit ascertained from specimens 

 which were cultivated in the Paris Garden in 1814. Also indigenous ones from 

 northern part of Mexico, i. e. in Chihuahua near Batopolas, Palmer, and near the 

 city of Chihuahua, Pringle. 



A. RETICULATA, Watsou, Proc. Am. Acad. xvii. 368. This species, in which 

 the arilliform covering of the seed was first discovered by Mr. Watson, has 

 smaller and more lobed leaves, an at length elongated naked raceme of flowers, 

 small and " blue " corolla, and a different fruit from that of A. parvijlora. The 

 carpels are more erect, wholly muticous, barely puberulent, at maturity with 

 exocarp bivalvular, thus dividing the capsule into 10 narrowly oblong almost 

 membranaceous and barely concave valves, liberating the still attached coarsely 

 reticulated husks, Ccach filled by a seed. 



A. CRENATiFLORA, Ort. Dec. viii. 96. Not having this part of Ortega's De- 

 cades, I cannot say if Cavanilles rightly referred this species to his A. parvijlora. 

 If so the name has a year's priority in publication ; but the petals being entire, 

 the name may be passed by as false for this species. 



A. INCARNATA, HBK. Nov. Gen. & Spec. v. 266, described from a plant culti- 

 vated in the Botanic Garden of Mexico, has not been identified and perhaps is 

 not of the genus. 



A. puBESCENs, Schlecht. in Linnaea, xi. 218, from Mineral del Monte, Ehren- 

 berg, is not made out.
