MARCH 19, 1021 BLAKE: AMERICAN SPECIES OF MAXIMILIANS A DJl 



This species is readily distinguished by its combination of digitate leaves 

 and single apical anther pore. M. tctrapora, which is said by Hallier to have 

 the leaves occasionally with three leaflets, is easily separated by its much 

 smaller calyx, much narrower lanceolate leaflets, and anthers with two apical 

 pores.

fCochlospermum zahlhruckneri Ostermeyer, Rep. vSp. Nov. Fedde 13: 395. 

 1914. 



Leaves long-petioled, at first sparsely pilose, the leaflets 5 to 7, rarely 3, 

 verv shortly petiolulate, the blades lanceolate, membranaceous, with a very 

 narrow acumen at apex, attenuate at base, the two basal ones inequilateral, 

 the middle leaflet 10.3 cm. long, 2 cm. wide; peduncles dichotomous, glabrous; 

 pedicels 2.5 cm. long, glabrous; sepals ovate or elhptic, 10 to 12 mm. long, 

 5 to 8 mm. wide, the inner densely puberulous and ciliolate; petals obovate, 

 excised, -i cm. long, 2.5 cm. wide; anthers 3 to 4 mm. long, dehiscing by two 

 ap.'cal and two smaller basal pores; capsule fusiform-subglobose, glabrous, 

 2.3 cm. long, l.S cm. wide. 

 Type Locality: Caipipendi \'alley, Bolivia. 



Not seen; described by Hallier from //t'rsog 1101, collected on dry hills on 

 the left bank of the Pilcomayo at Ibiboba, Bolivia, at an altitude of 400 

 meters, in November, 1910, and Herzog 1242,' from the Caipipendi Valley, 

 altitude 1000 meters, December, 1910. As the material of the former num- 

 ber consisted only of three flow^ers, the latter should be selected as the type. 



The short description by Ostermeyer of his Cochlospermum zahlhruckneri 

 agrees very wxll with the full description given by Hallier of C. tetraponim, 

 and there can be little question that the two are the same. The former was 

 based on material collected by J- Schuel in 1913 in the Province of Jujuy, 

 Argentina, a region very close to the type locality of M. tetrapora. Oster- 

 meyer gives the local name of his species as "palo papel." The reddish 

 brown papery exfoliating bark of Af . tetrapora is likewise mentioned by Hallier.
