The typical form has the leaves somewhat pubescent beneath. The form 



described as var. pohliana by Kichler, with slightly larger and thicker always 



3-lobed leaves, seems unworthy of recognition. Two other varieties, which 



appear sufficiently distinct for recognition by name, are the following: 



Maximilianea regia glaberrima Cliod. & Hassl. Bull. Herb. Boiss. II. 3: SIO. 

 1903. 



Leaves strictly glabrous. 



Described from Hassler 4934, from Nundurucay, and 4392, from the Rfo 

 Capibary, Paraguay. Said to be a shrub 30 to 40 cm. high. 



Maximilianea regia mattogrossensis (Pilger) Blake. 



Cochlospermum insigne var. mattogrossensis Pilger, Bot. Jahrb. Engler 30: 

 176. 1901. 



Leaves densely and shortly cinereous-tomentose beneath. 



Described from Pilger 518, from the upper Cuyaba Valley, Matto Grosso. 

 vSaid to be a shrub with several unbranched stems from a thick rootstock.

Large or small tree; branchlets at first loosely pilose; petioles more or less 

 pubescent, glabrate, 8 to 28 cm. long; leaves usually 54obed, rarely 3- or 

 7-lobed, for one-half to three-fourths their length, 10 to 33 cm. wide, above 

 more or less puberulous along the impressed veins, beneath loosely pilose 

 along the veins and in youth along the chief veinlets, the lobes oblong to 

 oval or obovate-oval, shoit-pointed or abruptly short-acuminate; inflorescence 

 sordid-pubescent, the axis 3 to 9 cm. long, the spreading or ascending branches 

 several-flowered toward the tip ; pedicels densely puberulous or tomentulose, 

 2 to 3 cm. long; flowers 7.5 to 12.5 cm. wide; two outer sepals ovate to oblong- 

 ovate, obtuse to lounded, sparsely or densely puberulous, 10 to 12 mm. long, 

 the three inner broadly oval, rounded, finely and densely cinereous-puber- 

 ulous, 16 to 22 mm. long; stamens free, the anthers opening by an apical pore 

 and 2 minute basal pores; capsule broadly obovate-oval, 7 to 8 cm. long, 

 about 6 cm. thick, densely griseous-tomentellous, 5-valved, umbilicate at 

 apex; seeds involute-reniform, 4.5 mm. wide, involved in long whitish wool.
