PLANTS COLLECTED IN ECUADOR

The cited specimen agrees excellently in detail with the type and only previously 

 known collection, Mathews 1442 , from the Department of Amazonas, Peru. In no. 

 1697 the corolla has a fugacious white puberulence as well as the characteristic 

 and more persistent brownish glandular hairs, this being the only difference noted 

 between it and the type. 



Macleania recumbens A. C. Smith, sp. nov. 



Frutex subrecumbens, ramulis gracilibus subteretibus brunneis glabris mox de - 

 corticantibus; petiolis rugulosis 3-5 mm. longis superne angulatis; laminis sub- 

 coriaceis in sicco fusco-olivaceis ovatis, (3.5-)7-ll cm. longis, (2-)3-7 cm.

 gradatim angustatis raro tantum breviter acuminatis, margine integris leviter 

 recurvatis, supra glabris, subtus dispersim et minute glanduloso-strigillosis, costa 

 et nervis utrinsecus 2 vel 3 ad 2 cm. supra basim orientibus adscendentibus supra 

 impress is subtus valde elevatis, venulis subimmersis; floribus axillaribus solitar- 

 iis bracteis pluribus papyraceis deltoideis subacutis circiter 1 mm. longis subtentis, 

 pedicellis gracilibus striatis (forsan 5-sulcatis) sub anthesi 8-9 mm. longis basim 

 versus minute bibracteolatis; calyce turbinato sub anthesi circiter 9 mm. longo et 

 apice 6 mm. diametro, tubo elongato circiter 7 mm. longo basim versus obscure 

 pallido-glanduloso-strigilloso alis carnosis circiter 1.5 mm. latis manifeste 

 5-alato, limbo erecto minutissime 5-denticulato, sinibus complanatis; corolla 

 carnosa cylindrica circiter 25 mm. longa et basim versus 5 mm. diametro, faucibus 

 contracta, intus apicem versus albido-pilosa alioqui glabra, lobis 5 oblongis sub- 

 acutis circiter 3 mm. longis; staminibus 10 circiter 11 mm. longis, filamentis in 

 tubum glabrum submembranaceum circiter 5 mm. longum connatis, antheris 7.5-8 

 mm. longis, thecis 4.5-5 mm. longis basi inflexis, tubulo unico 2.5-3 mm. longo 

 conic o, rima ovali subaequilonga; stylo filiformi corollam subaequante truncate 



El Oro: In Moro-Moro region (about 21 miles west of Portovelo), 3,400-4,200 ft. 

 elev., Oct. 7, 1944, Camp E-627 (TYPE US 1,988,986; dupl. NY) (plants subre- 

 cumbent, with some branches to 1 m. long, in dense rain-forest; flowers solitary in 

 axils of leaves; corolla deep coral-red). 



The new species is probably most closely related to M. floribunda Hook., dif- 

 fering in its larger and longer-acuminate leaf-blades and its essentially glabrous 

 (rather than distinctly castaneous-glandular-strigillose) flowers. The species in 

 this section of Macleania (i. e. the species numbered 1 to 6 in my key in Contr. 

 U. S. Nat. Herb. 28: 360. 1932) are fairly close and are not well represented in 

 herbaria; an eventual reconsideration of specific lines will certainly be desira- 

 ble. Within this alliance, the new species is close only to M. floribunda and M. 

 angulata Hook., being distinguished from the latter by having its leaf-blades more 

 definitely narrowed at both ends, its flowers solitary and with much shorter pedi- 

 cels, and its corolla cylindric rather than angled. 



Macleania sleumeriana A. C. Smith, Contr. U. S. Nat. Herb. 29: 367. 1950. 



Pichincha: Western slope of the cordillera, along the road from Quito to Sto. 

 Domingo de los Colorados, about 6,000 ft. elev., Camp E-1735 (NY only) (terrestrial 

 shrubs 0.4-1 m. high; leaves deep green above, pale beneath; upper part of pedi- 

 cels and hypanthium bright red-orange at anthesis, later fading to cream-yellow, 

 with only the wings red -tinged; base of corolla reddish coral, the upper half 

 deep green). 



The species {Anthopterus ericae Sleumer, non Macleania ericae Sleumer) 

 appears to be rare; this is only the third collection known to me, all being from 

 northern Ecuador.
