320 A FLORA OF MANILA 



lobes not extending beyond the middle of the leaf, the sinuses usually bWad, 

 acute. Flowers axillary, solitary or somewhat fascicled, pink, about 1.7 mm 

 in diameter. Fruit depressed-globo^se, about 7 mm in diameter, the 6 carpels 

 covered with short, retrorsdy barbed spines. (FL Filip. pL SiS, U: muliA- 

 fida.) 



In waste places, fl. all the year; throughout the Philippines. Tropics 

 generally, but certainly an introduced plant in the Philippines. 



yar. siNUATA (L.) Gagnepain. (U. ginuata L.). 



Very similar to the preceding and qertainly not specifically distinct, 

 differing in most of its leaves being deeply and often narrowly subpalmately 

 lobed, the sinuses extending beyond the middle of the leaf, rounded, often 

 narrow. Flowers and fruits as in the species. All interg^rading leaf -forms 

 are often found on the same plant. 



More abundant in the vicinity of Manila than is U. lobata and with the 

 same habitat, and Philippine and'extra-Philippine range.. 



Var. scABBiuscuLA (DC.) A. Gray. 



Similar to the species, but the leaves with very, broad and shallow lobes, 

 both surfaces rather densely hirsute, the lower surface much paler than 

 the upper, the branchlets and inflorescence ferruginous pubescent. 



In waste places near Fort McKinley, fl. all the year. Less common than 

 the other forms in the Philippines. India to Malaya. 



6. MALVAVI8CUS Dillenius 



Shrubs or small trees, more or less hispid or pilose. Leaves variously 

 toothed or lobed. Flowers red, peduncled, axillary, bracteolate. Calyx 

 6-lobed. Corolla exserted, campanulate. Staminal-column long-exserted, 

 antheriferous near the apex. Ovary 5-celled, cells 1-ovuled; style-branches 

 10. Fruit subglobose, somewhat fleshy, tardily separating into 6 inde- 

 hiscent carpels. (From Malva, another genus of the family, and the Latin 

 "offspring.") 



Species about 6 in tropical America, a single one introduced and culti- 

 vated in the Philippines. 



*1. M. PILOSUS (Sw.) DC. Gomamela de China (Sp.-Fil.). 



A shrub 1.5 to 2 m high, all parts with scattered, stellate-hispid hairs. 

 Leaves ovate, 6 to 10 cm long, irregularly toothed, acuminate, base broad, 

 5- to 7-nerved. Flowers in the upper axils, erect, red. Bracteoles about 

 7, linear-oblong, as long as the calyx. Calyx green, 5-lobed, 1 cm long. 

 Corolla about 2.5 cm long, the lobes strongly imbricate. Staminal-column 

 long-exserted, slender. Fruit surrounded by the persistent calyx and brac- 

 teoles, about 6 mm in diameter. 



Occasionally cultivated for ornamental purposes, fl. Oct.-Mar., and 

 probably in other months. A native of the West Indies. 



7. KOSTELETZKYA Presl 



Herbs, often suffrutescent, usually more or less hispid. Leaves orbicular 

 to ovate, more or less toothed or lobed. Flowers axillary, solitary, pe- 

 duncled, the bracteoles 7 to 10, linear. Calyx 5-lobed. Staminal-column 

 entire or 5-lobed, slightly exserted. Ovary 5-celled, cells 1-ovuled; style 

 branches 5. Capsule 5-angled, loculicidally dehiscent. (In honor of V. P. 

 Kosteletzky, a Bohemian botanist.)
