408 ^ FLORA OF MANILA 



2. 0. SANCTUM L. Albahaca (Sp.-Fil.) ; Solasi, Balanoi (Tag.)i Colocogo, 

 Camange (Vis.); Biday (IL). 



An erect, herbacepus or suffri^tescent, branched plant 1 m high or less, 

 the stems and younger parts jubescent with spreading hairs. Leaves 

 oblong-ovate, obtuse or acute, somewhat toothed, 2 to 4.5 cm long. Racemes 

 5 to 14 cm long, sometimes panicled.- Pedicels about as long as the calyx, 

 spreading, curved. Calyx at time of flowering about 3 mm long, some- 

 what larger in fruit, the two lower teeth long-awned, the upper one 

 broadly oblong, the lateral ones very broad, mucronate. Corolla pink 

 6r purplish, but little longer than the calyx. (Fl Filip, pi. t57.) 



Cultivated for its very fragrant leaves, occasionally also spontaneous 

 in waste places, fl. Dec.-Feb.; throughout the Philippines, but certainly 

 not a native of the Archipelago. Western Asia to Malaya, Australia, and 

 Polynesia. 



3. M CSC H OS MA Bentham 



Annual or perennial, erect, branched herbs. Leaves petioled, ovate to 

 oblong-ovate, thin, toothed or entire. Inflorescence axillary and terminal, 

 of rather slender, panicled racemes, the whorls few-flowered. Flowers 

 very small. Calyx ovoid, 5-toothed, the upper 3 teeth the largest, margins 

 not decurrent. -Corolla-tube very short, the upper lip shortly 4-fid. Stamens 

 4, declinate, the filaments free. Nutlets compressed, smooth. (From the 

 musk-like odor of some of the species.) 



Species about 6, tropics of the Old World, 1 in the Philippines. 



1. M. TENUiFLORUM (Bum.) Heynh. (M. polystachyum Benth.). 



An erect, much-branched, nearly glabrous herb 40 to 90 cm high, the 

 stems prominently 4-angled. Leaves long-petioled, thin, ovate. to oblong- 

 ovate, acuminate, toothed, 2 to 6 cm long, the base acute. Racemes 3 to 

 lO cm long, 5 to 6 mm in diameter, densely many-flowered. Pedicels 

 shorter than the calyx. Flowers lilac or pink, about 2.5 mm long, the 

 calyx in fruit spreading or somewhat reflexed, 3 to 3.5 mm long. 



In open places, occasional, fl. Dec-June; widely distributed in the Phil- 

 ippines about towns, but certainly not indigenous. Tropical Africa and 

 Asia through Malaya to Australia, 



4. HYPTIS Jacquin 



Erect, branched, aromatic or not. Leaves opposite, toothed. Inflor- 

 escence various, capitate, in dense spikesj or in remote, few-flowered, 

 paniculate clusters. Calyx straight or oblique, 5-lobed, lobes acute or awn- 

 tippedi Corolla 2-lipped, the lower lip abruptly deflexed, saccate. Stamens 

 4, declinate. Nutlets -various. (From the Greek "laid back" and "under," 

 in reference to the deflexed lower corolla-lip.) 



A large genus of over 250 species, all American, a few now distributed 

 as tropical weeds, 4 in the Philippines. 



1. Strongly aromatic herbs, the flowers in few-flowered, racemosely disposed 

 clusters....- _ _ , 1. H, suaveolens' 



1. Not on but slightly aromatic; heads axillai-y or terminal, solitary, subglo- 

 bose to oblong, densely many-flowered.

 3. Heads very shortly peduncled, peduncles not longer ^han the heads. 



2. H. brevipea 

 3. Heads long-peduncled, the peduncles many times as long as the heads.
