 14. Cassia glandulosa L. 



(Urban, 276.) 



A herbaceous or suffrutescent plant 0.5 to 1.5 meters high; leaves 5 to 8 cm. long; 

 leaflets oblong-linear, membranous; peduncle 1 to 3-flowered; sepals 1 cm. long; petals 

 1.5 to 2 cm. long, yellow; stamens red; legume 3 to G cm. long, 5 to 6 mm. wide. 



In sandy districts near Bayamon; Sierra de Naguabo, on the rocks on Mount 

 Piedra Palada and on the banks of the Rio Blanco; between Aibonito and Algarrobo, 

 along roads; between Aibonito and Coamo, on precipices; near Utuado, on declivities 

 at Pellejas and at Mameyes and in rocky districts at Los Angeles; near Sabana Grande,

Cassia glandulosa has often (as by Linnaeus himself) been confounded with other 

 species, but it can be distinguished from Cassia chamaecrista in that its petiole bears a 

 stipitate gland between the lowest pair of leaflets (and sometimes several below the 

 upper pairs) and in that the pairs of leaflets are usually much more numerous. Cassia 

 chamaecrista has sessile depressed glands. 



Local name, tamarindillo , hcdiondilla. 



15. Cassia mirabilis (Poll.) Urb. 

 (Urban, 276.) 



Stem suffrutescent, glabrous; leaves pinnate, 2 cm. long; petiole 1.5 cm. long, with 

 two stipitate glands; leaflets 10 to 17-jugate, 5 mm. long, 1 mm. wide, oblong, rounded 

 at both ends, papyraceous, glabrous on both sides, shortly petiolulate, mucronate; 

 stipules lanceolate, acuminate, 3 mm. long; flowers yellow; legumes 2 to 2.5 cm. long, 

 3 mm. wide, brown, glabrous, papyraceous, apiculate. 



Near Manati, in sandy soil on the edge of Tortuguero Lagoon at Campo'Alegre; 

 between Manati and Vega Baja in sandy soil; near Dorado, in the meadows of the 

 coast. 



16. Cassia nictitans L. 



Urban, 276.) 



Annual, herbaceous or suffrutescent, pubescent, with curved hairs, or glabrescent; 

 leaflets 12 to 25-(rarely 5-) jugate, 0.4 to 1 cm. long, oblong-linear, mucronulate, slightly 

 oblique at the base, penninerved, striate with veins; petiole bearing a stipitate gland 

 below the lowest pair; stipules exceeding the insertion point of the gland, acuminate 

 from a lanceolate, oblique base; peduncle l-(to 3-) flowered, much exceeded by the 

 leaves; stamens 5 to 7 (or even 10); legume bearing scattered curved hairs; petals 0.6 

 to 0.8 cm. long. Variable in the petiolar glands, which are long-stipitate or subses- 

 sile.
