APOCYNACE^:. 



CARRUTHERSIA Seeiminn. 



Carruthersia macgregori comb. nov. 



Ellerionia macyrcgori Merrill in Govt. Lab. Publ. (Philip.) 35 (lOOG) 59. 



A reexamination of the type material, and study of additional specimens 

 collected by Mrs. Clemens in Mindanao, no. 756, September, 1906, and without 

 numbers, April and June, 1907, leads me to refer this species to Carruthersia, 

 the second sj)ecies of the genus to be found in the Philippines. It is closely 

 allied to Carruthersia pilosa (A. DC.) F.-Vill., but is readily distinguished by 

 its glabrous leaves. The stamens are very slightly united and the two lobes of 

 the disk alternating with the carpels are present. The genus EUertnnia is thus 

 to be e.x:cluded from the Philippine flora. 



STROPHANTHUS DC. 



Strophanthus erectus sp. nov. 



Frutex erocta^ 1 ad 2 m alta; foliis submcinbranaceis, elliptieo-ovatis 

 vel oblongo-ovatis, breviter acuminatis^ nervis utrinque 5 vel 6 ; cymis 

 paiicifloris, bracteis et lobis calycinis lanceolatis, aciuninatis, staminum 

 aristis antheris o-plo longioribus; corollae lobis ca. 13 cm longis. 



A glabrous erect shrub 1 to 2 m high, the branches brown or reddish- 

 brown, terete, lenticellate, the branchlets slightly compressed. Leaves 

 elliptical-ovate to oblong-ovate, 8 to 13 cm long, 3 to 6 cm wide, submeni- 

 branaceous, glabrous, dull or slightly shining, paler beneath, the apex 

 short-acuminate, the base rounded to acute or somewhat acuminate, some- 

 times slightly inequilateral ; nerves 5 or 6 on each side of the midrib, very 

 prominent, anastomosing, the reticulations lax, distinct; petioles 1 cm 

 long or less. Cymes terminal, glabrous, few-flowered, the bracts and calyx 

 lobes lanceolate, long-acuminate, the latter 7 to 9 mm long. Corolla 

 tube white, slightly yellow within, 2 cm long, about 8 mm in diameter, 

 slightly constricted at the middle, enlarged above, the lobes about 8 mm 

 wide at the base, attenuate into long, slender, drooping, yellowish tips, 

 a1)0ut 13 cm long; appendages about 1 cm long, cleft into two long, 

 slender, acuminate parts. Anthers 3 mm long, sagittate at the base, the 

 filaments very short, somewhat hirsute, the apical awn very slender, 

 about 15 mm long. Ovary glabrous; style cylindrical, about 12 mm 

 long. Follicle woody, oblong-ovoid, about 1(3 cm long, 7 mm wide; 

 seeds lanceolate, 1.5 to 2 cm long. 



Palawan, Puerto Princesa, Merrill 6D5, February, 190.3; also specimens culti- 

 vated in Manila from seeds taken from this specimen, Merrill 5176, March, 190(1, 

 and Cuzner, February, 190S. 



This species diflfers from Strophanthus cumingii DC, in its much longer petals 

 and appendages to the anthers and in other characters; it appears to be more 

 clo.sely allied to S. dicholornus DC, than to ;Sf. cumingii DC.
