A species strongly characterized by its glabrous, or nearly 

 glabrous, oblanceolate leaves, and by its dense, fascicled, cauline 

 inflorescences. 



SAURAUIA LANAENSIS sp. nov. 



Arbor parva, ramulis petiolisque adpresse setosis, foliis subtus 

 ad costa nervisque adpresse-setulosis ; foliis oblanceolatis, 11 ad 

 20 cm longis, tenuiter acuminatis, deorsum angustatis, basi cu- 

 neatis, margine spinulosis, supra glabris, laevis, nervis utrinque 

 10 ad 12, perspicuis, reticulis distinctis ; cymis axillaribus, pauci- 

 floris quam petiolo brevioribus, plus minusve setosis; floribus 

 parvis, sepalis leviter subadpresse-setosis, circiter 3 mm longis; 

 ovario glabro; stylis 4, liberis. 



A shrub or small tree, 3 to 5 m high, the branchlets appressed- 

 setose with short, brown, lanceolate scales, the petioles and mid- 

 rib on the lower surface with similar scales. Leaves charta- 

 ceous, oblanceolate, 11 to 20 cm long, 3 to 6 cm wide, the apex 

 slenderly acuminate, narrowed to the cuneate base, the margins 

 somewhat spinulose, the upper surface smooth, olivaceous, gla- 

 brous, the lower surface paler, appressed-setose with short scales 

 on the midrib and lateral nerves ; lateral nerves 10 to 12 on each 

 side of the midrib, distinct, anastomosing, the reticulations 

 evident; petioles 1 to 1.5 cm long. Inflorescences of very short, 

 axillary, solitary or fascicled, few-flowered cymes usually 1 cm , 

 or less in length, the rachis and pedicels setose. Flowers white, 

 small, the sepals elliptic-ovate to oblong-ovate, about 3 mm long 

 and 2 mm wide, with few, slender, subappressed setae up to 1 mm 

 in length. Petals narrowly oblong-obovate, about 5 mm long, 2.5 

 mm wide, the apex somewhat inequilaterally retuse. Anthers 

 about 1.2 mm long. Ovary ovoid, glabrous; styles 4, free, 2 

 to 2.5 mm long. 



Mindanao, Lanao District, Camp Keithley, Mrs. Clemens 868, 

 collected at various times on the forested slopes of Sacred Moun- 

 tain, altitude about 800 meters: Misamis Province, Mount Ma- 

 lindang. For. Bur. 4683 Mearns & Hutchinson, May, 1906, in 

 forests, altitude about 700 meters. 



Among the Philippine forms this species is well characterized 

 by its oblanceolate, slenderly acuminate leaves, and its short, 

 few-flowered, axillary cymes, and small flowers.
