superiori instructis; spinis circa 20 inaequalibus 1.5 cm. non superanti- 
bus non pungentibus plus minusve arcuatis flavo-fuscis ; glochidiis paucis 
(circa 50) in summa parte areolae sitis et non arcte pungentibus apice 
obtusis ; spinis lateralibus glochidiarum non eminentibus ; ovario paulo 
quam 3 cm. longiore turbinato tuberculato; areolis quam illae articularum 
non mivoribus 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 in fundo infimo floris 
crateriformis insertis permultis; stilo 2 cm. longo crasso; stigmatibus 
6 erectis incurvatis carnosis percrassis.” — WENMAN IsL.: Snodgrass 
ffeller, no. 917 (hb. Berl. & hb. Gr.). “ Note.—The relatively large 
flower brings this species near O. myriacantha, Web., from which a 
differs in the mode of ies smaller articles, and non-pungent 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 
with definiteness to any of the foregoing species. Dr. Baur’ says of 
the genus: ‘Die grosse Opuntia hat einen verschiedenen Charakter 
beinahe auf jeder Insel. Die Opuntia von Barrington, Indefatigable 
und siid-Albemarle z. B. entwickelt einen sehr hohen Stamm; die von 
Hood und Charles besitzt einen verhiiltnissmiissig niederen und dickeren 
Stamm; die Opuntia von Jervis wiederum einen sehr niederen; die 
Verzweigung beginnt schon kurz iiber 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 O. Helleri from 
the not very distant island of Wenman.
