FLORA OF THE GALAPAGOS ISLANDS. 181 



superiori instructs; spinis circa 20 inaequalibus 1.5 cm. non superanti- 

 bus non pungeiilibus plus minusve arcuatis flavo-fuscis ; glochidiis paucls 

 (circa 50) iu summa parte areolae sitis et non arete pungeutibus apice 

 obtusis ; spinis lateralibus glocbidiarum non emiuentibus ; ovario paulo 

 quam 3 cm. longiore turbmato tuberculato ; areolis quam illae articularum 

 non miuoribus et a lano modice copioso tectis et a spinis capillaceis 

 modice laxis ad 2 cm. longis flavo-fuscis munitis ; perigonio 3-3.5 cm. 

 maximo diametro ; lobis exterioribus subulatis, 3 mm. longis, sequenti- 

 bus late ovatis acutis mucronatisve verosimiliter flavo-viridibus, intimis 

 subobovatis fere 2 cm. longis ; staminibus fere iu fundo infimo floris 

 crateriformis insertis permultis ; stilo 2 cm. longo crasso ; stigniatibus 

 6 erectis incurvatis carnosis percrassis." — Wenman Isl. : Snodgrass & 

 Heller, no. 917 (hb. Berl. & lib. Gr.). "Note. — The relatively large 

 flower brings this species near 0. myriacantha, AVeb., from which it 

 differs in the mode of growth, smaller articles, and uon-puiigent spines."

Opuntias also occur (ace. to field notes of several collectors) upon 

 Abingdon, Barrington, Bindloe, Chatham, Culpepper, Duncan, Hood, 

 Narborough, North and South Seymour, and Tower Islands, but as no 

 specimens of them have been secured it is impossible to refer them 

 vvrith definiteness to any of the foregoing species. Dr. Baur^ says of 

 the genus : " Die grosse Opuntia hat eiuen verschiedenen Charakter 

 beinahe auf jeder Insel. Die Opuntia von Barrington, Indefatigable 

 und slid-Albemarle z. B. entwickelt einen sehr hohen Stamm ; die von 

 Hood und Charles besitzt einen verhjiltnissmassig niederen und dickeren 

 Stamm ; die Opuntia von Jervis wiederum einen sehr niederen ; die 

 Verzweigung beginnt schon kurz liber dem Boden ; die Opuntia von 

 Tower hat gar keinen Stamm, die Verzweigung beginnt sofort am Boden, 

 es ist ein niederer Busch, aber- kein Baum. Die Form von Bindloe 

 zeigt Charaktere, die zwischen den Individuen von Tower und Jervis 

 liegen." It seems not unlikely that the low plant on Tower lacking the 

 main trunk may be the same as Professor Schumann's 0. Helleri from 

 the not very distant island of Wenman.
