Sec remarks under plate 2891. Botb this and S, bogotcnse, Iluber, 

 have somewhat peculiar petioles ; the upper part next the blade and 

 between the glands is channelled or furrowed and extends downwards 

 for a short distance as a closed tube, whilst the lower part of the petiole 

 is solid. Untortunately this peculiarity is not well brought out in 

 the drawing. — W. Bottixg Hemsley,
