ORCHIDACEiE 



H.jaliscana fleshy oblong appendages at base, 1^ lines long; stigmatic pro- 

 cesses 1 J lines long. Rio Blanco in moist bottoms; August. (343). 

 — Flowers greenish yellow. This (as the following) may be some 

 one of the species named by Richard h Galeotti,but their descrip- 

 tions certainly do not apply to the specimens." Wats. loc. dt. 



H.jaliscana resembles H. Schaffnerl In the mature flowers, 

 however, the spur is much more slender than in H. Schaffneri 

 and about 3 cm. long. The anterior divisions of the petals are 

 unusually long, as is shown in the specimen from which Richard 

 prepared his drawing of H. alata. 



Pringle's no. 4508 as represented by specimens in my herbarium 

 agrees in almost every detail with the type of H. alata Rich. & 

 Gal., preserved in the herbarium of the Museum d'Histoire Na- 

 turelle de Paris. Richard's material is in excellent condition for 

 comparative studies. The specimens collected by Galeotti at 

 Mirador give the following measurements. Dorsal sepal about 

 6 mm. long, orbicular-oblong, acute. Lateral sepals 11 mm. long, 

 4.5 mm. wide. Petals: posterior division 8 mm. long, 1.5 mm. 

 wide, falcate-linear; anterior division 13 mm. long. Middle lobe 

 of the labellum 14 mm. long. Lateral lobes basal. (Plate 74.)
